Verifone decline Codes

Normally, this means the customer's balance is insufficient or that the CVV on the back of the card was rejected. However, an issuing bank may decline a transaction if there is a certain velocity of transactions taking place on that specific card or if the purchase pattern is out of the statistical norm or it represents an unusual purchase pattern and other aggregated data for that card

It's important to note too that it's the issuing bank that makes the approval or decline decision, as opposed to the merchant processor (Sterling/Chase Paymenttech/First Data?VITAL, etc..) or the Gateway (gotoBilling) who plays no role in the process at all. And to further confuse the matter, every issuer sets their own criteria for the decline process and it varies greatly.

Other examples of "Auth declined 200" are that one issuing bank may decline on an outdated expiration date while another issuing bank may approve a card with an outdated expiration. And a third issuing bank may sometimes decline and sometimes approve in that situation depending on other data points such as the card purchasing pattern that day, the velocity of transactions, etc.
