Could anyone explain a little more simply about what is ARQC and how to generate ARQC?
Do you know the algorithm VISA and MasterCard uses to generate the ARQC? Thanks for your help in advance.

Each EMV transaction request is supposed to contain ARQC, which is a cryptogram generated from the transaction data. A cryptogram can be thought of as a digital signature on the financial transaction.
ARQC generation steps:
1. Card Key Derivation
2. Session Key Derivation
3. Preparation of Input Data in ARQC Calculation
4. Encryption/ Hashing (the final step that gives the ARQC)
