Apple Pay Authorization
So somebody help me please understand this: Scenario: I was at Office Depot yesterday and was paying at the counter with my business debit card but I had issues with the new pin I was issued with so I just went ahead and process it as a credit and everything went smoothly.Fast forward couple of hours later, I was checking my personal bank account and saw that whole thing was charged on it even though I didn't even use the card! So I called my bank and my business bank and asked why the transaction happen when i only had one card out and I clearly didn't put my personal card out..turns out Apple Pay processed it without ME PULLING OUT MY PHONE OUT OF MY POCKET NOR SWIPING OR HOVERING IT OVER THE DEVICE and without my authorization or finger print. So somebody please tell me, is this all legal and how is this possible??? I mean I was clearly using a different card and I wasn't even alerted that my apple pay was being used. should I be worried that my cards in my apple pay can be used without my permission and anybody with an apple pay friendly device can scanned it without me knowing it??
P.S. My phone is an iPhone 7 and updated to the latest version.
iPhone 7, iOS 10.3.1
