Appendix G. Contactless ATM Requirements
G.2 Requirements
Note: After the reader has returned to discovery processing as described above, the cardholder may:
– Re-present the same consumer device as was used for the original transaction after having performed any necessary interaction (for example, enter their passcode on a mobile phone).
– Choose to present a different contactless card or consumer device.
– Choose to insert a card into the contact reader.
The reader does not retain any card information from the original transaction. If a contactless card is detected, the reader will perform a SELECT PPSE and continue normal processing based on the response from the card. If a contact card is inserted, the contactless reader will be powered down as specified in this document and a normal contact or magnetic stripe ATM transaction will be performed.
G.2.20
Switch to Another Interface Required
Switch Interface Required
If either:
•
The card indicates that the transaction should be attempted over a different interface (GET PROCESSING
OPTIONS response SW1 SW2 = ‘6984’). or:
•
The ATM identifies that the transaction should be attempted over a different interface (as described in sections
G.2.12 and G.2.13
).
The contactless-enabled ATM shall:
•
Power down the contactless interface.
•
Discard all card data captured from the contactlessinitiated transaction.
•
Display the “Please insert card” message (as specified in
EMV Contactless Specifications for Payment Systems) to indicate that the transaction should be re-started using contact chip or magnetic stripe.
Switch Interface: Enable All Other Interfaces
Immediately after the indication to switch interfaces has been displayed, the reader shall enable all interfaces other than contactless (i.e., contact chip and magnetic stripe).
