Which Processors Support Card Verify (FRC 2F)
All EMV-capable American processors now support Card Verify (2F) requests. If you are not on an EMV-capable processor, code results may vary, and an update to the processing platform may be needed.
Note: If Shift4 does not support the Card Verify function for a particular processor, a $1 authorization is requested instead. A response with no errors is received with the response field equal to 'A,' valid AVS, and/or CVV/CSC equal to 'Y.'
