Single Tap
Only supported for Visa and Mastercard.
When a card issuer responds to a contactless payment attempt, with specific response codes the cardholder must enter/re-enter the Online PIN.
| CardScheme | Response Code |
|---|---|
| MasterCard | 65 (Additional customer authentication required) or 55 (Invalid PIN) |
| Visa | 70 (PIN data required) or 55 (Invalid PIN) |
If the POS device supports Single-Tap the cardholder will only need to subsequently enter the Online PIN at the terminal PIN entry device (PED) without the need to tap again or perform a chip and PIN transaction.
Merchants that have POS devices that support Single-Tap should indicate this in all contactless authorization requests initiated from those devices.
Notice
In order for Single-Tap to work the card issuer must also support this feature. It will be indicated in the authorization response.
-
To indicate that a POS device supports Single-Tap, use parameter SingleTapSupported = 1 in the authorization request.
-
To indicate that the card issuer supports Single-Tap, the parameter SingleTapSupported = 1 will be included in the authorization response.
If the card issuer supports Single-Tap, the merchant initiates the subsequent authorization and includes Online PIN data (PinBlock and PinBlockKeyIndex) , SingleTapSupported = 1, SingleTapFollowUp = 1 and the TransLCID from the original response if available.
The merchant should not reuse the MsgID from the original request.
