  1. Analysis as to proceed as Online/Offline or Decline offline is done by terminal and card. Read about terminal risk management, terminal action analysis, issuer action analysis in detail(TAC-Online, TAC-Denial, TAC-Default, IAC-Online, IAC-Denial, IAC-Default). EMVCo Books 3 will help. Based on the cryptogram information data (9F27) terminal comes to know of the cards decision whether it was to go offline, online or decline.

  2. 91, 71, 72 and 9F18
