Data encryption

The service is activated for PSP on request.

The service enables payment card PANs to be converted into stamps, which serve as a secure representation of card data. The stamps can then be used to create File Sets in the Smart Routing service.

Stamps can be generated either from a PAN only or from a combination of PAN + card expiry date).

Using PAN + expiry date provides greater flexibility when configuring rules in the Smart Routing service, such as rules that reject transactions for a card after a specified number of failed transactions. When the PAN + expiry date combination is used, a reissued card with the same PAN but a different expiry date will not be subject to restrictions previously applied to the old card with the same PAN.
