I have worked with some of the payment gateways like PayHub, Braintree, Balanced. at the time of processing credit cards; I submitted a bunch of credit card
and its details as CVV, expiry date, Name of card holder, address
.
I come across that, through the same gateway, some times the details are being checked but some times not at all. After contacting to support team of gateway, they told me that, the details are checked by banks and varies by each bank.
Can anybody tell, which are the fields that bank compulsory validates?
