To the best of my knowledge, no major credit card companies allow the use of copied credit cards.
I think Coin will have to have a partnership with them, otherwise, Coin will be doomed from the
get go, because, you see the Coin screen displays the various Logos of credit card companies on the front
when being used, along with the last 4 digits of the credit card number.
If they don't have a partnership; Mastercard, Visa, Discover, Amex, etc, will have to either
license Coin's usage of their logo on the cards, or enforce the trademark rights and sue
Coin or send cease and decist displaying their logo and disseminating confidential magnetic track data
in an unauthorized manner.....
