What is ARQC

---

---

Each EMV transaction request is supposed to contain ARQC, which is a cryptogram generated from the transaction data. In the context of EMV, a cryptogram can be thought of as a digital signature on the financial transaction. A valid, verifiable cryptogram tells you two things:

• the financial message originated from the source that it claims to be from
• the contents of the message have not been altered
  

There are two cryptograms used in EMV: ARQC (Authorisation Request Cryptogram) and ARPC (Authorisation Response Cryptogram). The first one, ARQC, is generated by the card (after taking some values from the terminal), and hence it's part of a request message. The second one, ARPC, is generated by the issuer and hence it's part of a response message.
