If code was related to a payment-system then I would agree that the tag was useful.

Credit cards are not a payment system though, so none of those questions would qualify.

payment-system would be things like Moneris, EFT, Paypal, etc. I would expect the tag to relate to the Wikipedia entry at least a little bit:

The payment system is an operational network - governed by laws, rules and standards - that links bank accounts and provides the functionality for monetary exchange using bank deposits

I don't believe any Code Review questions referenced in the question have anything to do with payment systems, other than the following:

• Thread-safe wrapper around WCF ServiceModel.ClientBase subclass
• Secure CURL to & handle response from Payment Gateway

The rest have to do with shopping-cart and validation.

I don't believe the questions above have enough content specifically related to payment systems to make the tag worthwhile.
