I'm not sure a typical bank card detail form include an address. Usually it's card number, expiry date, CVV/CSC and (optional, as some cards don't have it!) cardholder's name. Not sure about Heroku and too lazy to remember a password and log in there to check right now.

Heroku may have address fields for invoices and stuff, but I really doubt they can validate it (except for country/state) with bank, as addresses are real mess. At the very least, not automatically. So, this probably won't work for abuse prevention.
