Simple Credit Card Validation rejecting VISA starting with 4366

[tammu]

We are Simple Credit Card validation to capture the order. Under module settings Visa is set to accept starting with 4 any 13 digits or 16 digits.

One of our customer said her card was not being accepted and I was able to replicate it when I tried to place her order thru online. and the only reason being her card number was starting with 4366

any idea why it would say not a valid number

Thanks and appreciate it

Re: Simple Credit Card Validation rejecting VISA starting with 4366

That is very odd. The simple validation module actually just performs a mod10 mathematical test on the number submitted to make sure it is potentially valid. If a card number fails that test, it is rejected. All credit card numbers are supposed to conform to that test. Perhaps they are entering the card number wrong or maybe don't have the card in hand and just noted it down and made a mistake?

You can actually attempt the same mod10 test manually if you want to double check that the card number is invalid; it's time consuming but easy:
