What is IAD in EMV?
Issuer Application Data. Contains proprietary application data for transmission to the issuer in an online transaction.
What is ARQC failure?
• The online ARQC is invalid or chip validation fails. These failures occur for a variety of reasons, including: – Key-related issue: Keys or key-related data from the card and in the issuer’s hardware security module (HSM) do not match.

What is an EMV card?
With an embedded microcontroller, chip cards have the unique ability to securely store large amounts of data, carry out their own on-card functions (e.g., encryption and mutual authentication) and interact intelligently with a card reader. All EMV cards are chip cards.
How are the terminal verification results (TVR) coded?
The Terminal Verification Results is coded according to Annex C.5 of [EMV Book 3]. Status of the different functions as seen from the reader/terminal. For EMV mode transactions, all of the TVR bits sent online to the acquirer shall be set to 0b. Status of the different functions as seen from the terminal.
