_Agnos _version 3.5.20 _revision 23770 | Agnos Interface is an abstraction of EMVCo Book I, II, and III. It relies on 3 components: An EMV tags database to store all tags involved in a card processing A set of EMV application selection routines An EMV engine implementing EMV steps and EMV primitives to access internal states and structures
Image Added Pre-contions setup Use tTransactionContext C structure to initialize Agnos → see emvco.c, an example used to implement EMVCo test app required for EMVCo CT L2 TA Use agnSetEMVTag() calls to initialize Agnos
