This will be awesome for Starbucks! I always hate my phone auto-locking when i am in the drive-through and when I pull my phone out of the cup holder for the girl to scan my barcode. There is a 6 or so step process to get back to that barcode after unlocking.
Ideal yet secure use.
--------------------------
Step 1) Tap StarBucks icon in the lower left corner
Step 2) Be prompted to authenticate with TouchID
result) My Starbucks gift card barcode is displayed
Yes, I drink way too much expensive coffee.
Yes, I am too lazy to get out of my truck and walk inside.
You can already do this in the Starbucks app by setting favorite stores and passbook
