Amazon Go

Other interesting possible implications of this:

1) The inability to pay with cash (or debit, or check, etc..). 2) No need to carry any form of money in the store.

Taken to an extreme where every store runs this way, will people have a need for cash, credit cards, or anything else? Why not just have your bank account attached to your Amazon (and every other account) and have money taken out directly?

As a security guy, that is terrifying.
