I assume it's easier in the sense that your waiter could add your card to his Coin, then immediately go buy a TV at the store with it. Not having to make a fake card or needing the address of the card holder to use it online.

As with some other people in cousins comments to your post, I think you may not realize that that attack is already perfectly feasible today. By "feasible" I mean real criminals already do this today, not merely that some academics hypothesize that it may be possible. It's all very off-the-shelf stuff. If you're worried about this attack, the solution isn't "don't use Coin someday in the future", it's "don't use anything with a magnetic strip, today".

Its a bit hard to read the mag stripe by eye - unless your a mutant in which case call in Phil Coulson's team stat

The majority of credit cards still have actual numbers on them.

Except that the CVV from the magstripe is missing - wich means ypu can only use the printed CNP CVV, ie. only use the card data for internet transactions.
