  • Convenient: After you first add your card to your device, it will be saved for easy access. Your Mobile Wallet can be used anywhere the contactless symbol black and white contactless symbolis shown and – you don’t have to worry about forgetting your wallet. As long as you have your phone, you are good to go.
  • Secure: Your Mobile Wallet is more secure than your physical debit card. Card numbers are never transmitted to the merchant, keeping your information private.
