That’s actually very interesting. Thanks.

Do they do this via a partnership with MasterCard or something? Basically similar to prepaid cards?

They should be using an issuing processor (a financial institution that works with Visa or MasterCard) to issue card numbers. Issuing processors can easily generate card numbers programmatically + on the fly.

Thanks for the info. I haven’t heard the term issuing processor before.
