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.

🛒 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.
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.
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.
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.
Custom splash screens
Display 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 tipping
For 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 recognition
The 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 promotions
Promotional 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 scanning
Customers 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 support
The 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 signing
Where required (for example, fuel delivery agreements or rental authorisations), customers can sign electronically on the terminal touchscreen -- no separate signature pad needed.
Customer engagement features (loyalty, tipping, splash screens, QR scanning) are configured by your Verifone deployment team. Contact your Verifone account manager if you want to enable or customise these features for your site.

How the Terminal Stays Up to Date
Unlike older terminals that required a technician visit or manual USB update to change the software, the M425A can receive software updates remotely -- either through Verifone's cloud management system or directly from Commander on-site.
Via VHQ (Verifone HeadQuarters) -- Cloud Updates
VHQ is Verifone's cloud-based device management platform. When a new version of EVPay or a configuration update is approved and ready, VHQ automatically pushes it to the terminal during a scheduled maintenance window -- typically overnight, outside of trading hours.
Updates are applied automatically -- no action needed from the site operator or cashier.
The terminal waits until it is idle (no payment in progress) before applying the update.
After the update, the terminal restarts and returns to the payment screen ready for use.
All terminals at a site can be managed and updated centrally without visiting each one individually.
Via Verifone Commander (On-Site, On-Demand)
For sites that want to check or update the terminal software on-site, Verifone Commander can also manage EVPay updates directly -- without needing cloud access or a VHQ workflow.
From Commander's configuration screen, an operator can see which EVPay version is currently running on any connected M425A.
If a newer approved version is available, an update can be triggered directly from Commander -- no technician visit required.
The update does not interrupt an active payment transaction.
For most sites, VHQ handles routine software updates automatically. The Commander on-demand update is an additional option for sites that prefer to manage updates themselves or need to apply an update immediately.

Hardware Installation
The setup procedure for the M425A in the following sections:
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).

The 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.
2
Network is configured
The 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.
3
Identity certificate is loaded
A 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.
4
Encryption keys are loaded
For 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.
5
VHQ connection is configured
The 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.
6
Configuration is applied from Commander
Terminal configuration (payment settings, prompts, fleet parameters, etc.) is applied from Commander's configuration client -- the same configuration process used with previous Verifone pinpads.
7
Test transactions are completed
The 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.
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.

Signature Capture
The Signature Capture electronically captures a signature when required for a network sale. See the Signature Capture Feature Reference on the Premier Portal for more information.
When a card is used and a signature is required, the customer is prompted for a signature on the Verifone M425A PINpad.
The printed receipt does not include a signature line, but depending on the configuration settings, may include the signature image.
Signature Capture saves receipt paper by allowing the cashier to decide whether or not to print a merchant and customer copy.
Signature Capture only applies when a signature is required.

Frequently Asked Questions
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.
