To start paying with your Curve Card via your Fitbit device you have to add it to the Wallet section of the Fitbit app:
- With your device nearby, tap the Today tab, and tap your profile picture.
- Tap your device image, then tap the Wallet tile.
- Follow the on-screen instructions to add a payment card. In some cases, your bank may require additional verification. If you’re setting up Fitbit Pay for the first time, you may be prompted to set a 4-digit PIN code for your device. Note that you also need passcode protection enabled for your phone.
- After you add a card, follow the on-screen instructions to turn on notifications for your phone (if you haven’t already done so) to complete the setup.
