"What is Apple Pay?
Apple Pay is a brand new way to pay, and Macy’s is proud to be one of the first stores to feature it!
Here’s how it works:
- Add your credit or debit cards to the Passbook app on your iPhone 6 or 6 Plus.
- Visit your favorite Macy’s store and shop!
- Use Apple Pay at checkout—hold your iPhone near the payment pad reader with your finger on Touch ID™.
- Wait for the vibration & beep to let you know payment is complete.
- Provide your signature if your total comes to more than $25.
- It's that easy!
