Device Setup
This section outlines the setup procedures for the M400, covering the following segments:
Terminal Location
Following are guidelines used to select an ideal location for the terminal.
Ease of Use
Select a location convenient for both the merchant and cardholder.
Select a flat support surface, such as a countertop or table, or mount it on a mounting stand supplied by Verifone.
Select a location near a power outlet, POS (Point-of-Sale), ECR (Electronic Cash Register), or computer connected to the terminal. Do not string cables or cords across a walkway for safety.
Environmental Factors
Do not use the unit where there is high heat, dust, humidity, moisture, caustic chemicals or, oils.
Keep the unit away from direct sunlight and anything that radiates heat, such as a stove or a motor.
Do not use the terminal outdoors.
The terminal is not waterproof or dustproof. It is intended for indoor use only. Any damage to the unit from exposure to rain or dust can void any warranty.
Le terminal n'est ni étanche ni étanche à la poussière. Il est destiné à un usage intérieur uniquement. N'importe lequel les dommages causés à l'appareil par l'exposition à la pluie ou à la poussière peuvent annuler toute garantie.
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).
Do not use the terminal near water or in moist conditions.
Disconnect the device from its POS terminal before cleaning.
Do not use the terminal 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 le terminal à proximité d'eau, notamment d'une baignoire, d'un lavabo, d'un évier de cuisine. ou une cuve à lessive, dans un sous-sol humide ou près d'une piscine pour éviter les chocs ou dommage.
Contactless Considerations
Avoid having metallic objects in proximity of the contactless antenna. If you need to mount the terminal to vertical or inclined surfaces, use a flat, non-metallic mounting plate.
Using an enclosed metal frame or mount may negatively affect contactless performance.
L'utilisation d'un cadre ou d'un support métallique fermé peut affecter négativement les performances sans contact.
PIN Protection Measures
Use the following techniques to provide effective screening of PIN-Entry Devices (PEDs) during the PIN-entry process. You can use these methods in combination, although in some cases a single method might suffice.
Position the terminal on the check-in stand in such a way as to block visual observation of the PIN-entry process. Examples include:
Visual shields were designed on 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 terminal 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 terminal 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.
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 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 queue
No action needed
Do not install within view of cameras
Verifone also recommends instructions to 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
Ensuring User Privacy
Use the following guidelines to protect the user's privacy when he enters his personal identification number (PIN):
The area of visibility should not be larger than a cone taken from the number 5 key at an angle of 45° and covering an area of 270° directly in front of the user.
You can secure PIN entry by installing a Ensuring User Privacy (optional).
Mounting Considerations
Verifone recommends the use of an approved stand for all mounting situations. Position the terminal conveniently in relation to power, POS, ECR, and LAN (Local Area Network) connections. Ensure the M400 device is located 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 will be swiveled during normal operation, Verifone requires the use of an approved swivel stand.
Inside the Shipping Carton
Open the shipping carton and carefully inspect its contents for possible tampering or shipping damage. The terminal is a secure product. Tampering causes it to cease to function or to operate in an insecure manner.
Unpacking the Shipping Carton
Do not use a tampered or damaged unit. The terminal comes equipped with tamper-evident labels. If a label or component appears damaged, please notify the shipping company and your Verifone service provider immediately.
