Thats pretty cool but the ATM i go to is never that busy and its not all that inconvenient for me. For me personally, i dont see a way that this would benefit me too much besides a cool factor. With that said, i can definetly see how this would help at a busy atm in the city or something. If everyone shaves only 20 secs off their transaction time then every 3 people would save a minute of my time being wasted standing in line lol.
Overall cool product. But i see it more as a "because we can" product haha.
