Apple Pay, Apple’s new mobile payments system for iPhones and iPads, launched Monday.
If you have an iPhone 6 or 6 Plus, you can use it to buy stuff in stores that have near field communication (NFC) pads on their credit card terminals.
Here’s a video that shows how you pay with Apple Pay at checkout. You just tap your phone on the NFC pad. Your credit card appears on the iPhone. Then you place your finger on the fingerprint sensor to validate the payment.
