Device Setup
This section outlines the setup procedures for the M424 covering the following segments:
Device Location
The following are guidelines used to select an ideal location for the device.
The device must be used in an attended environment.
Ease of Use
Select a location convenient for both the merchant and cardholder.
Select a flat support surface less than two meters high, such as a countertop or table, or secure the device on a stand mount supplied by Verifone.
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.
Do not use the device near water, including a bathtub, wash bowl, kitchen sink or laundry tub, in a wet basement, or near a swimming pool to avoid shock or damage.
N'utilisez pas l'appareil à proximité de l'eau, y compris d'une baignoire, d'un lavabo, d'un évier de cuisine ou d'une buanderie, dans un sous-sol humide ou à proximité d'une piscine pour éviter les chocs ou les dommages.
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 on the check-in stand in such a way as to block visual observation of the PIN-entry process. Examples include:
Visual shields are designed into the check-in stand. The shields may be solely for shielding purposes or may be part of the general check-in stand design.
Position the device 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 forwards/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.
The following table describes the two preferred mounting methods and the recommended measures to protect against PIN capture in four observation corridors:
Mounting Methods and Protection Measures
Countertop without stand
Use signage behind the PED
Install so that customer is between PED and next in the queue
No action needed
Do not install within view of cameras
Countertop with stand
No action needed
Install so that customer is between PED and next in the queue
No action needed
Do not install within view of cameras
Verifone also recommends instructing the cardholder regarding safe PIN-entry. This can be done with a combination of:
Signage on the PED
Prompts on the display, possibly with a click-through screen
Literature at the point of sale
A logo for a safe PIN-entry process.
You can secure PIN entry by installing a Privacy Shield (optional).
Mounting Considerations
Verifone recommends the use of an approved stand for all mounting situations. Position the device conveniently in relation to power, POS, ECR, and LAN connections. Ensure the M424 device is placed in a manner that allows customers to swipe their magnetic cards or insert their Smart Cards in a smooth and comfortable motion without encountering obstructions. If the unit needs to be swiveled during normal operation, Verifone recommends the use of an approved swivel stand.
