I tried to use android pay for a few months. In theory its great (and it's great when it works!) but like 30% of the time it doesn't really work the first time, you have to play around with it on the card reader. Then the phone vibrates like it worked but nothing happens. You look at the phone and it says "please hold the card to the reader again." and despite Subway accepting android pay (and the cashiers insisting that it works for everyone else) whenever I try to use it there I get a message "please insert card." I was never able to figure out the workflow to get it to work on a vending machine. Also the first time I used it I froze the register. So 70% of the time it saves time and 30% of the time it wastes time. Then I broke my phone and bought a replacement without NFC so I don't have the option anymore anyways. It's a great system, however, I think the kinks need to be worked out a little. (I had a Nexus 5x FYI)
