It's easy. Go into Settings on your eligible Apple‡‡ device, open the Apple Wallet & Apple Pay, and select Add Credit or Debit Card. On your iPhone‡‡, you can open the Wallet app, then swipe down and tap the plus sign. From there, use the iPhone camera to capture the information on your card, or type in the card number. If you already have a credit card registered to your iTunes‡‡ account, you can add it to Wallet by simply entering the card's security code (the three-digit number on the back of the card). If you have more than one Apple device that you are using with Apple Pay, you will need to add your BMO credit or debit card to each device.
You can also sign into the BMO Mobile App and add your BMO Credit or Debit card. Simply choose Apple Pay from the drop down menu and select the card(s) you would like to add. Don’t have the app? Download today
