What is ARQC and Arpc?
This service provides EMV Authorization Request Cryptogram (ARQC) and Authorization Response Cryptogram (ARPC) transaction processing. An ARQC is generated by the EMV card upon request from the point of sales terminal to obtain authorization for payment. Generation of the Authorization Response Cryptogram (ARPC).
What is Issuer Action Code?
