On: Detect breaches with Canary credit cards

[posix_compliant]

I’m dying to know how they implemented this. In order to have Visa or MasterCard process this transaction, they’d need to have a bank partner to issue the credit credit card with an issuer processor. There’s usually a large cost to keeping open credit cards on file, even if there’s no line of credit.

Only Amex at the moment.
