This document describes the basic flow for EMV fallback using the ID TECH L2 Common Kernel.


Fallback Flow:

Start EVM Transaction, "Is chip readable?"

if yes, proceed with transaction.

If no look at magstripe-service code for "is chip present on card?"

If yes, EMV_RESULT_CODE_FALLBACK_TO_MSR

if no EMV_RESULT_CODE_SWIPE_NON_ICC

If no magstripe or magstripe unreadable, EMV_NO_MATCHING_APP
