Generate and verify ARQC

An Authorization Request Cryptogram (ARQC) is a cryptogram generated by an EMV chip card (or digital equivalent such as a mobile wallet) during a payment transaction. The ARQC cryptographically validates the card and ensures the integrity of the transaction data. It incorporates card data, terminal data, and transaction-specific data to produce a unique value for each transaction.

AWS Payment Cryptography supports two ARQC operations. You can generate an ARQC for development and testing purposes, and you can verify an ARQC for production transaction authorization flows.
