FLEXIBLE EMV-COMPLIANT IDENTIFICATION TRANSACTION METHOD

Identification protocols, such as those developed by EMVCo LLC, ensure worldwide interoperability between POI terminals and chip-based payment applications and devices. These standardized data interactions are very limited, and make the implementation of new functionalities very difficult, and it takes years before the standards are agreed and implemented.An identification transaction method comprising: commencing, by a POI terminal, an EMV-compliant identification transaction with an identification devices; receiving, by the POI terminal, an indication from the identification device that the device may participate in non-EMV compliant identification transactions; responding by either: (a) continuing the EMV-compliant identification transaction with the identification devices if the indication is negative or no indication is received; or (b) commencing and continuing a non-EMV compliant identification transaction with the identification devices if the indication is positive.By implementing such a function selection, new non-EMV compliant functionalities may be quickly added to existing proprietary kernels. By quickly providing new functionalities, the migration to improved ID devices may be accelerated.
