Upgrading to iOS 8.1 was easy enough, but then what do I do with an Apple Pay enabled iPhone 6? You try it out on a break room vending machine, and amazingly Apple Pay worked!
First, I had to setup Apple Pay, associating my iTunes information for payment. Then I walked by the vending machine whereupon Passbook asked if I wanted to authorize a transaction using TouchID. After scanning in my fingerprint for a few seconds, the vending machine told me to make my selection. Out came my Coke Zero, and Passbook notified me of my $1.50 transaction. That’s it, that’s all, and it just worked.
