2.3.6.4.2. What is Contactless card payment?
The contact payment allows a cardholder to make a purchase without having
to hang over, swipe or dip a payment card. To make payment the cardholder
simply present the payment card in front of the contactless landing zone of
the terminal, defined by the logo:
A payment contactless will normally be an offline authorized chip transaction, the card can
be removed 500 milliseconds (ms) and the transaction will be completed in less than one
second.
In certain local markets and for international may be required after the card has been
removed.
2.3.6.4.3. The advantages of Contactless technology
Contactless technology offers several advantages:
Short transaction time: the ease of card to reader presentation and a high speed of
data transfer reduce considerably the transaction time. Because the transaction
time is reduced, business can increase speed and generate more revenue.
Reliability and lower costs: there is no mechanical contact between the card and the
reader so the damages of both card and reader are reduced. Thus, contactless
technology is reliable and reduces the maintenance cost of reader.
Vandal protection: Contactless technology increases protection against vandalism.
Whereas the contact slot of contact reader is often the target of vandalism acts,
contactless reader will not exposed to these problems.
Security: The use of contactless smart cards with a microprocessor allows for a high
level of transaction security and these cards are very difficult to duplicate.
2.3.6.5. SAM readers
The access to the SAMs is protected. It is located under a removable trap.
SAMs are identified by marking on casing “1” and “2”.
An optional third SAM is available. A SAM3 label identifies this option on the right of the
reader.
