Apple Pay and fingerprint
New to iPhone and the 6S. I"ve set up ApplePay and everything talks about paying by using your finger/thumbprint. I've set up a 6 digit passcode to access ApplePay/Wallet (still trying to understand both) but can I pay with it using that 6 digit code or do I need to do something with a finger/thumbprint?
Also...we are going to by flying on Delta in a week from now and it says I can use this for my boarding pass. How do I get a boarding pass into the wallet to use it to board the plane?
Thanks...any help would be appreciated
iPhone 6s, iOS 9.3.2
