Fallback

Simplify supports fallback to MSR input if the card cannot be read or the card applications are not supported. Status Messages sent by Simplify during fallback processing return a Status Identifier of 023.

If swiping also fails, fallback to manual entry is supported (configurable). Fallback to manual entry is indicated in the response to the POS as follows: Field 54 = 79. Field 57 = 3.
