The card generates the ARQC. Its format depends on the card application. EMV does not specify the contents of the ARQC. The ARQC created by the card application is a digital signature of the transaction details, which the card issuer can check in real time. This provides a strong cryptographic check that the card is genuine.
Terminal verification results (TVR) or Tag '95' [1] is an EMV data object . The TVR is a series of bits set by the terminal reading an EMV card, based on logical tests (for example has the card expired). This data object is used in the terminal's decision whether to accept, decline or go on-line for a payment transaction.

A card cryptogram is sent to an issuer bank (smart card, EMV). An issuer bank verifies the PIN or check card cryptogram. An issuer bank makes finance verification (on-time limit, credit limit, ...) An issuer bank sends OK or !OK (+optional command list for EMV card). (The recrypt PIN block process is not included in list.)
