M425A device's enriching features allow electronic payment transactions to be processed in multi-lane scenarios with combined card payment with a variety of Verifone cloud-based services including Advanced Payment Methods, e-comm capabilities such as Buy Online Pick-Up in Store, and the ability to dynamically configure multi-media driven promotional content at the counter. This payment processing device can scan barcodes, QR codes, and products with the help of an integrated camera. In combination with Verifone Connect digital services, it offers the ability to run Android applications, like loyalty and inventory. It also enables clients to remotely monitor and update their devices using Verifone's estate management solution. The best-in-class M425A device will be able to communicate to the ECR via serial over USB and IP over USB simultaneously and support multiple SAM cards for transaction processing. Verbal Message Supporter is a new significant feature where the user will be able to speak into the terminal microphone to state their issue or raise a question that will be received by the Verifone Support Administrator. It also supports video playback from a serial digital memory interface to play training videos for staff and promotional content to customers at or near the checkout counter or in the lane. It transforms the customer's journey into a simple walk-through by providing different connection options like an external power supply, USB, and Ethernet. ### *M425A Device*
This document explains what is changing, what the new terminals can do, how they look and feel compared to what you have today, and how software updates are managed going forward. It is written for site operators, managers, and anyone who works with or beside these terminals -- not for technical or IT staff. ### Why Is Verifone Upgrading the Terminals? The terminals used at many fuel sites today -- the MX915, MX925, and M400 -- are reaching the end of their supported life. The MX900-series devices reach end of service in 2026, and the M400 devices reach their payment card security expiry (PCI) in April 2026. Once a terminal passes its PCI expiry, it can no longer legally process card payments. The M425A is built on Android and certified to the latest payment security standards (PCI PTS 6 and 7), which will remain valid for many years ahead. Moving to these devices now ensures sites can continue processing card payments without interruption. | Old Terminals | M400 | M450A / M425A (New) | | ----------------------------- | --------------------------- | ----------------------------------------------- | | MX915 / MX925 | M400 | M450A / M425A | | VOS platform (older OS) | VOS2 platform (older OS) | Android 13 -- modern, fast, secure | | ViperPay application | EVPay application | EVPay on Android (VIPA 7) | | End of service: 2026 | PCI expiry: April 2026 | PCI 6/7 -- valid for years ahead | | No contactless on some models | Limited card format support | Full contactless, chip, swipe, fleet, debit PIN | ### Terminal at a Glance The M425A is a high-performance, multi-lane payment terminal designed for retail and countertop use.

### What Is New with the M425A | 📱 Android Platform Runs on Android 13 -- a modern, fast, and secure operating system. Faster screen response and a familiar smartphone-like feel. | 💳 All Card Types Chip, tap-to-pay (NFC), swipe, fleet cards, debit PIN, PIN bypass, digital wallets. Every card your customers carry is supported. | 🎨 Refreshed Payment Screen Completely redesigned UI -- larger fonts, better-sized buttons, cleaner layout. Easier for customers with small or large hands. | | ----------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------- | | 🔄 Automatic Updates EVPay software updates are pushed automatically via VHQ (cloud) or from Commander on-site -- no technician visit needed for routine updates. | 📷 QR & Barcode Scanner Customers can scan digital coupons, loyalty app barcodes, and QR codes directly from their phone screen -- no paper required. | 🛒 Customer Engagement Display custom splash screens, on-screen tipping prompts, loyalty recognition, and online specials directly on the terminal screen. | ### The Refreshed Payment Screen (EVPay UI) The payment screen on the M425A has been completely redesigned based on direct feedback from cashiers and customers at fuel sites. The goal was to make it cleaner, easier to read at a glance, and less prone to accidental taps. | What Changed | The Old Experience | The New Experience | | --------------------------- | --------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------- | | Button size and layout | Buttons stretched the full width of the screen. Customers found them hard to read and easy to tap accidentally. | Buttons are a more natural size -- easy to see and tap precisely, whether you have small or large hands. | | Font size | Text on the PIN pad and payment prompts was small and difficult to read, especially in bright outdoor light. | Larger, clearer fonts throughout the payment flow -- easier to read for all customers. | | Contactless icon placement | The contactless (tap) icon was placed where cards sometimes triggered it accidentally. | The contactless area is repositioned and clearly marked to reduce accidental triggers. | | Scroll bars | Narrow scroll bars were difficult to grab and drag on a touchscreen. | Wider, more touch-friendly scroll bars -- and layouts are redesigned to minimise scrolling altogether. | | Number of choices on screen | Limited options were visible at once, requiring multiple screen taps to complete a simple selection. | More choices visible at once, reducing the number of screens a customer taps through. | {% hint style="info" %} The payment process for customers is unchanged -- 1) tap, insert, or swipe card, 2) enter PIN if prompted, 3) confirm amount. Only the look and feel of the screen has improved. {% endhint %} ### Customer Engagement Features The M425A is not just a payment device. Its vibrant 5.5-inch touchscreen can be used to create richer checkout experiences for your customers -- without any extra hardware.
FeatureWhat It Means for Your Site
Custom splash screensDisplay your brand, promotions, or site-specific messages on the terminal screen when it is idle. Customers see your content while waiting to pay, not just a blank screen.
On-screen tippingFor sites that offer tipping (car washes, food service, etc.), tip prompts can be shown directly on the terminal screen. Customers select a tip amount before confirming payment -- no separate tip slip needed.
Loyalty programme recognitionThe terminal can recognise returning loyalty customers and display personalised prompts -- for example, showing a customer their current points balance or a targeted reward offer as they pay.
Online specials and promotionsPromotional offers and digital specials can be displayed on the terminal at the point of payment -- encouraging add-on purchases or informing customers of current deals.
QR code & barcode scanningCustomers can scan digital coupons, loyalty barcodes, or QR codes directly from their smartphone screen. The terminal reads the code instantly -- no paper coupon needed.
Self-checkout supportThe M425A can be used in a self-checkout configuration, giving customers the option to complete their own purchases during busy periods -- reducing queue time without additional staffing.
Alternative payment methods (APMs)In addition to card payments, the terminal is designed to accept alternative payment methods -- such as digital wallets and any payment type configured by your Verifone deployment team.
Electronic document signingWhere required (for example, fuel delivery agreements or rental authorisations), customers can sign electronically on the terminal touchscreen -- no separate signature pad needed.

## Hardware Installation The setup procedure for the M425A in the following sections: * [Device Location](#device-location) * [Environmental Factors](#environmental-factors) * [Electrical Considerations](#electrical-considerations) * [PIN Protection Measures](#pin-protection-measures) * [Inside the Shipping Carton](#inside-the-shipping-carton) * [Device Features](#device-features) * [Connection Ports](#connection-ports) * [MSAM Card](#msam-card) * [Micro SD (TF) Card](#micro-sd-tf-card) * [Powering the Device](#powering-the-device) * [Smart Card Reader](#smart-card-reader) * [Magnetic Card Reader](#magnetic-card-reader) * [Contactless Smart Card Transaction](#contactless-smart-card-transaction) * [M425A Wi-Fi/BT Support](#m425a-wi-fi-bt-support) * Optional Accessories ### Device Location The following are guidelines used to select an ideal location for the device. * Select a location convenient for both the merchant and cardholder. * Select a location near a power outlet, POS, ECR, or computer connected to the device. For safety, do not string cables or cords across a walkway. #### Environmental Factors * Do not use the device where there is excess heat, dust, humidity, moisture, caustic chemicals or oils. * Keep the device away from direct sunlight and anything that radiates heat, such as a stove or a motor. * Do not use the device outdoors. #### Electrical Considerations * Avoid using this product during electrical storms. * Avoid locations near electrical appliances or other devices that cause excessive voltage fluctuations or emit electrical noise (for example, air conditioners, electric motors, neon signs, high-frequency, or magnetic security devices, or computer equipment). * Avoid using the device near water or in moist conditions. * Disconnect the device from its POS device before cleaning. WARNING: Do not use the device near water, including a bathtub, washbowl, kitchen sink or laundry tub, in a wet basement, or near a swimming pool to avoid shock or damage. ### PIN Protection Measures Use the following techniques to provide effective screening of the PIN-entry keypad during the PIN-entry process. You can use these methods in combination, although in some cases a single method might suffice. * Position the device in such a way as to block visual observation of the PIN-entry process so that it is angled in such a way that PIN spying is difficult. * Install the PED on an adjustable stand that allows consumers to swivel the device sideways and/or tilt it forward/backward to a position that makes visual observation of the PIN-entry process difficult. * Position in-store security cameras so that the PIN-entry keypad is not visible. * This risk of shoulder-spying during PIN entry can be significantly reduced by installing the optional approved privacy shield. * Verifone also recommends instructing the cardholder regarding safe PIN-entry or using the Privacy Shield for secure PIN entry by installing a Privacy Shield (optional). ### Inside the Shipping Carton Open the shipping carton and carefully inspect its contents for possible tampering or shipping damage.

Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death. These suggestions apply equally to your device, or any of its attachments or accessories. If your device is not working properly, take it to the nearest authorized service facility for servicing or replacement. For your safety, have this device serviced only by a Verifone-authorized service provider. ### Additional Safety Information The following are additional safety information in using this device. #### Surface Cleaning To clean the device, use a clean cloth slightly dampened with water and a drop or two of mild soap. For stubborn stains, use alcohol or an alcohol-based cleaner. {% hint style="warning" %} CAUTION: Never use thinner, trichloroethylene, or ketone-based solvents -- they can deteriorate plastic or rubber parts. Do not spray cleaners or other solutions directly onto the device. {% endhint %} #### Smart Card Reader Cleaning The Smart Card Reader (SCR) must be cleaned on a regular basis, as dirt accumulation can lead to SCR reading problems. SCR can be cleaned using commercially available card reader cleaning cards or using recommended Verifone cleaning card (PN 02746-02). To clean the SCR: {% stepper %} {% step %} Inspect the device's SCR for presence of foreign objects before cleaning Customer Smart Card. If unit shows no presence of foreign objects, test the SCR function and record results. Proceed to Step 2. {% hint style="warning" %} CAUTION: Send your device to a Verifone authorized repair center if foreign objects are found in the SCR at any time during SCR inspection, test diagnostics, or cleaning process. Removal of foreign objects from the SCR by customers may void device warranty. {% endhint %} {% endstep %} {% step %} Clean the SCR with approved or recommended Verifone cleaning card. It is always advised to use new cleaning cards at all times. {% hint style="info" %} NOTE: If using a commercially available cleaning card use ONLY an approved SCR cleaning card made specifically for POS SCR devices or Petroleum SCR. {% endhint %} {% endstep %} {% step %} Test the SCR after cleaning. 1. If SCR tests out okay as "passing", then the unit is ready for Customer Smart Card use. 2. If SCR tests out as "failing", then send the unit for repair. Provide details to repair center when SCR failed testing, either before cleaning OR after cleaning OR both before and after cleaning. {% endstep %} {% endstepper %} #### Magnetic Stripe Cleaning The Magnetic Stripe Reader (MSR) must be cleaned on a regular basis (daily to once a week, depending on usage), as dirt accumulation can lead to MSR reading problems. MSR can be cleaned using commercially available card reader cleaning cards or using recommended Verifone cleaning card (PN 02746-02). {% hint style="info" %} NOTE: If using a commercially available cleaning card use ONLY an approved MSR cleaning card made specifically for POS MSR Card reader devices or Petroleum MSR card readers. {% endhint %} ## Software Installation EVPay software comes pre-installed on the M425A from the factory. However, a setup visit is still required to configure the terminal for your specific site. A Verifone technician or your designated setup contact handles all of the following steps -- you do not need to perform them yourself, but this overview helps you know what to expect during an installation.
1Operating system is confirmed / updatedThe terminal arrives with the correct Android OS pre-installed. The technician confirms the version is correct for your site type (production) and applies any OS updates if needed.
2Network is configuredThe terminal is set up with the correct network address (IP, gateway, DNS) so it can communicate with the Commander site controller over your local network. This can be done over Wi-Fi or via an Ethernet cable.
3Identity certificate is loadedA digital identity certificate is installed. This acts as the terminal's badge -- it tells Verifone's systems which organisation this terminal belongs to. Without it, the terminal cannot connect to the payment backend.
4Encryption keys are loadedFor debit PIN transactions, encryption keys are loaded onto the terminal remotely and securely via the TR34 standard. These keys are unique to this terminal and are never typed or entered manually.
5VHQ connection is configuredThe terminal is pointed to the correct VHQ instance so it can receive future automatic software updates. By default, petroleum terminals connect to Verifone's PetroHome VHQ instance.
6Configuration is applied from CommanderTerminal configuration (payment settings, prompts, fleet parameters, etc.) is applied from Commander's configuration client -- the same configuration process used with previous Verifone pinpads.
7Test transactions are completedThe technician runs test payments -- chip, tap, swipe, and debit PIN -- to confirm everything works correctly with Commander and the payment network before the terminal goes live.
{% hint style="warning" %} If a terminal is replaced or swapped, the full setup process above must be completed for the new unit. A replacement terminal arrives factory-fresh -- it does not inherit settings, certificates, or encryption keys from the old device. {% endhint %} ## Configuration This chapter describes configuring the Verifone M425A.

Do I need to do anything differently when a customer uses the new terminal? No. The payment steps for customers are identical. The screen looks cleaner and is easier to read, but customers follow the same prompts -- tap, insert, or swipe their card and enter PIN if prompted. No retraining is needed.
Will the terminal accept all the cards my customers use today? Yes. The M450A and M425A accept chip cards, contactless tap (including Apple Pay and Google Pay), magnetic stripe swipe, fleet cards, debit PIN, and PIN bypass. All payment types in use today are fully supported.
Can customers scan their loyalty app or digital coupons? Yes. The terminal has a built-in scanner that reads QR codes, barcodes, and PCR codes directly from a customer's phone screen -- no paper coupon needed. Ask the customer to open their loyalty app or coupon and hold it near the terminal.
How will I know if the terminal is receiving a software update? The terminal may display a brief notification during an update. Do not power off the terminal during this time. Updates complete automatically and the terminal returns to the payment screen when done.
Does the terminal support Apple Pay and Google Pay? Yes. The M425A / M450A fully supports all NFC contactless payments -- Apple Pay, Google Pay, Samsung Pay, and other digital wallets. Customers hold their phone or watch near the contactless symbol on the screen.
Will we need to reconfigure Commander when the terminals are replaced? No. Commander configuration for payment settings remains the same as with your previous Verifone pinpads. The configuration client works in the same way -- your existing Commander configuration does not need to be rebuilt.
What if the terminal shows an error code I do not recognise? Note the error message shown on screen and contact your Verifone support line. Take a photo with your phone if possible. Do not attempt to reset or reconfigure the terminal yourself -- error codes require trained support staff to diagnose.
Is the terminal safe from tampering? Yes. The terminal is fitted with tamper-evident labels and built-in tamper detection. If someone attempts to physically open or interfere with the device, it disables itself automatically. It contains no user-serviceable parts -- do not attempt to open it.
Do I need to do anything when the terminal restarts after an update? No. The terminal restarts automatically after an update and returns to the payment screen on its own. If a customer was in the middle of a payment, the update waits until the transaction is complete before applying.
What happens to my existing M400 or MX900 terminals? They are replaced with M450A or M425A terminals as part of your site's upgrade. Old terminals are decommissioned after the new ones are installed and tested. Your Verifone account manager can give you the timeline for your specific site.

## Troubleshooting Guidelines This chapter lists typical examples of malfunctions that you may encounter while operating your device and the steps that you can take to resolve them. The troubleshooting guidelines provided in the following sections are included to assist successful installation and configuration of the device. Please read these troubleshooting examples if you are having problems operating your unit. Contact your local Verifone representative for assistance if the problem persists even after performing the outlined guidelines or if the problem is not described. {% hint style="info" %} NOTE: The device comes equipped with tamper-evident labels. It contains no user-serviceable parts. Do not, under any circumstance, attempt to disassemble the unit. Perform only those adjustments or repairs specified in this guide. Contact your local Verifone service provider for all other services. Service conducted by parties other than authorized Verifone representatives may void any warranty. {% endhint %} {% hint style="warning" %} CAUTION: All units require use of a power supply. Use only a Verifone-supplied power pack. Using an incorrectly rated power supply may damage the unit or cause it not to work properly. Ensure that the power supply used to power the unit matches the requirements specified on the back of the unit (see Specifications for detailed power supply specifications) before troubleshooting. If not, obtain the appropriately rated power supply before continuing with troubleshooting. {% endhint %} ### Device Does Not Start If the device does not start: * Ensure that the device is plugged into a dedicated power source. * Check power cable connector is plugged in properly. ### Device Display Does Not Show Correct/Readable Info If the device display does not show correct/readable info: * Check all cable connections. If the problem persists, contact your local Verifone representative for assistance. ### Blank Display When the device display is blank: * If the device display is dark, tap the screen with the stylus or your finger. If the unit was in screen-saver mode, the screen will turn on when touched. * If the display does not show correct or readable information, check all cable connections. If the problem persists, contact your local Verifone representative for assistance. ### Keypad Does Not Respond If the keypad does not respond properly: * Check the device display. If it displays the wrong character or nothing at all when you press a key, follow the steps outlined in Transactions Fail to Process. * Refer to the user documentation for that application if pressing a function key does not perform the expected action to ensure you are entering data correctly. * Contact your local Verifone representative if the problem persists. ### Transactions Fail to Process There are several possible reasons why the unit may not be processing transactions. Use the following steps to troubleshoot failures. #### Checking Magnetic Card Reader To check magnetic card reader: 1. Perform a test transaction using one or more different magnetic stripe cards to ensure the problem is not a defective card. 2. Ensure that you are swiping cards properly (see Magnetic Card Reader). 3. Process a transaction manually using the keypad instead of the card reader. If the manual transaction works, the problem may be a defective card reader. 4. Contact your local Verifone representative if the problem persists. #### Checking Smart Card Reader To check smart card reader: 1. Perform a test transaction using several different smart cards to ensure the problem is not a defective card. 2. Ensure that the card is inserted correctly (see Smart Card Reader). 3. Ensure the MSAM cards are properly inserted in the slots and are properly secured (see MSAM Card). 4. Contact your local Verifone representative if the problem persists. The following steps cover the most common issues a cashier or site manager might notice. For anything beyond these basics -- or if the issue persists after following the steps below -- contact your Verifone support representative. {% hint style="warning" %} The M450A / M425A contains no user-serviceable parts. Do not attempt to open or disassemble the terminal under any circumstances. The device is fitted with tamper-evident labels -- physical tampering will disable the terminal and void any warranty. Only authorised Verifone service personnel may service the hardware. {% endhint %} | Symptom | What to Check | If It Persists | | ------------------------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------- | | Terminal does not power on | Confirm the power cable is plugged in firmly at both ends. Ensure the terminal is connected to a dedicated power outlet -- not a shared power strip with other equipment. | Contact your Verifone support line. Do not attempt to open or repair the unit. | | Screen is blank or dark | Tap the screen with your finger -- if the terminal was in screen-saver mode, the screen will turn on when touched. Check that the power cable is connected. | Check all cable connections. If the screen remains blank after touching, contact Verifone support. | | Screen shows incorrect or unreadable information | Check all cable connections. Restart the terminal by holding the power button (if available) for a few seconds. | Contact Verifone support -- do not attempt to reconfigure the terminal yourself. | | Keypad does not respond | Check whether the on-screen display shows the correct prompts. Try a different function or step in the payment flow. | If pressing keys produces no response or wrong characters, call Verifone support. | | Card transactions failing -- chip read errors | Try a different chip card to confirm it is not a damaged card. Ensure the customer is inserting the card correctly (chip end first, face up). Try a second or third card. | If multiple different cards also fail, the chip reader may be faulty. Contact Verifone support. | | Card transactions failing -- magnetic stripe | Try a different card. Ensure the customer is swiping smoothly in one direction at an even speed. Try swiping the card the other way. | If multiple cards fail to swipe, the magnetic card reader may be faulty. Contact Verifone support. | | Tap to pay not working | Ensure the customer is holding their card or phone within 2-4 cm of the contactless symbol on the screen. Ask the customer to unlock their phone or open their wallet app before tapping. | If tap payments consistently fail with multiple cards/phones, contact Verifone support. | | Terminal not connecting to network | Check that the Ethernet cable is plugged in (if using a wired connection) or that the terminal is within Wi-Fi range. Confirm the network is active. | Contact your Verifone support line -- network configuration issues require trained staff to diagnose. | {% hint style="info" %} When calling Verifone support, have the terminal serial number ready. It is printed on a label on the back of the terminal. The support team may also ask for the error message shown on screen -- take a photo with your phone before calling if possible. {% endhint %} --- # Agent Instructions This documentation is published with GitBook.
