Yes, you can enable Tap to Pay on more than one device, so every staff member can use it on their own mobile.
Once the account owner or manager enables Tap to Pay, staff members can go to Business Settings > Payments & Checkout > Tap to Pay and check if there are any access requirements for their device, such as location, NFC or Bluetooth. Once they enable access, they’ll be able to start using Tap to Pay at Checkout.
