Ya, but it looks really cool to walk up to the Starbucks teller and tap your iWatch. Until it doesn't work, which happen in front of me at a Starbucks a few months back. Note to all you cutting edge/young ultra uber cool people - it really looks good when it works. Until it doesn't, and then you look like a fool. And you're in my way.
I had the Starbucks Pay app years ago and it kept falling asleep while I was in line. Screw that.
If I can walk by your phone sitting on a table and tap it with my hidden Square tap-to-pay credit card reader and it doesn't wake up or send any kind of 'are you sure?' message please, please let me know where you hang out.
