I rode the UTA Trax line today (Utah Train System) and they have this "tap on tap off" system, where to board the train all you have to do is scan your phone at a terminal and hop on, then scan again when you get off. It is very handy when a train is at the station and it is about to leave and you don't have a ticket. Just tap and go. To check tickets, the authorities hop on your train randomly with a little device with NFC built in, so you just tap your phone and it tells them whether you have paid or not. I have noticed though that of the 5 times I've used the tap on tap off system, I've never been charged for the ride, (Google Wallet always says "unknown status") and when the authorities came to me for my ticket today and scanned my phone, a red "ERROR" message appeared on his device and he said "That seems about right" and walked away. It was pretty funny. Dunno what's up, but hey, free train ride.
One thing that bugs me though, is that living in Salt Lake City, I hear about this ISIS wallet thing constantly and how it's so "revolutionary" and you need a special SIM card to use it and blah blah blah. I love having Sprint, because I can still use Google Wallet. All the Verizon users are blocked from using Google Wallet and have to use ISIS. I went to Verizon a couple days ago and they had a vending machine for "Susie's Lemonade" (teehee) and the text scrolling across the price thing said something about being an ISIS only machine, and you needed a representative to get a demo... so I pulled out my phone, tapped it, got my lemonade for a cent. The employees were kinda stunned. So I bought another one. Susie's Lemonade sucks, though. Unless you like straight lemons.
