I slipped my workspace ID card into the case for my iPhone 6s Plus, since I usually have my phone out when I get out of the elevator anyway. This works well, I wave my phone at the reader next to the door and it opens.

But I notice the Apple Pay screen comes up too when I do that.

Does that mean its NFC chip is the same as my ID card, and a clever app could emulate my card?
