I am working on having our system identify fallback transactions. The Worldpay ISO 8583 Reference Guide V2.25 shows 2 POS Entry Mode values for fallbacks:
What is the difference between the 2 codes? Does a "79" mean that, since there is prior voice authorization, the transaction is not suspicious?
Thanks!
Hi Scott,
It was my understanding that the value of '79' originally meant "fallback to manual entry". In otherwords, the chip could not be read and the mag stripe could not be read, so the card number was manually entered. That being said, when we certified for EMV, we were told that we could not send a value of '79' to Vantiv. What we had to do was, when the device sent us a value of '79' we translated that into a value of '01' (manually entered). so, my current understanding is that '79' is not a valid fallback value that we can send to Vantiv. Hope this helps.
Good Afternoon Scott,
Once a card insert fails at a terminal, its to fallback to a magnetic swipe (Value: 80 - "Fallback from Chip to magnetic stripe"). 79 is used in when manually keying a card # after a CHIP read fail and a MAG Stripe fail, and its been called in (like a referral). I hope this answers your question.
