Square Card Case
3 November 2011
So once you opt-in one time to the geofencing feature in the app, when you (and your phone) are within 100 meters of a Square merchant you can simple [sic] walk into the store, say your name at checkout and you are good to go with the payment. You don’t need to pull your phone out at all or open the app.
Like I said, the future of payments isn’t going to involve little bits of plastic.
