Always there for you

Mastercard has setup rules for contactless point of interaction transactions across Europe with the aim to improve the cardholder experience.

The requirement is that in case the issuer needs to request Strong Customer Authentication (SCA) and the counter reaches its limit during a contactless low-value transaction, Mastercard requires that the cardholder will only need to enter their PIN at the Terminal without the need to tap again or perform a chip and PIN transaction. This process is called the Single Tap Solution.

It is mandatory that every contactless transaction on appropriate contactless-capable terminals must support the Single Tap service, regardless of the transaction amount or Strong Customer Authentication (SCA) presence.

The transaction will be flagged as non Single Tap supportive in case all of the following three rules are met:

• the terminal is contactless capable;
• the transaction is contactless;
• the terminal does not support Single Tap processing for contactless transactions

The effective date for German, Danish, Norwegian and Swedish merchants is October 1st 2022. For Finnish merchants the effective date is January 1^st 2024.

If you have an agreement with a third party terminal supplier, please contact your partner to agree compliant set-up. If you have internal processes to manage transactions on payment cards, please ensure that these follow the procedures mentioned above.  

You will see these charges appear on your settlement report. 

The Data Element of the transactions will show DE 61 [Point-of-Service (POS) Data], subfield 11 [POS Card Data Terminal Input Capability Indicator] equals a value of 3 or 4.

The Data Element of the transactions will show DE 22 [Point-of-Service (POS) Entry Mode], subfield 1 [POS Terminal Primary Account Number (PAN) Entry Mode] equals a value of 07.

The Data Element of the transactions will show DE 48, subelement 22 [Multi-Purpose Merchant Indicator], subfield 02 [Single Tap Indicator] does not equal a value of 1.
