To help stop fraud; I added a credit card verification feature that charges then refunds a random amount from $0.01 - $3.00.
I know scammers can easily find fraudulent credit cards to use on the internet, but I feel like having this credit card verification feature helps a lot. Because the scammer would then also need to know the online login information for the credit card to find out what the random amount charged is.
I think this is a good feature to help stop fraud, but do you think scammers could also get login information along with credit card information? Or is this something that is less likely to happen?
