Jawbone is teaming up with American Express to bring contactless mobile payments to its latest fitness tracker, the UP4. The band contains an integrated NFC chip that you can use with any contactless Amex terminal. Pairing is simple too, all you do is use the UP app to sign into your card account, pick your card, and voila! you're ready to go.
The band is based on the UP3 design which features a new set of sensors to give you advanced activity and sleep tracking as well as heart rate tracking. No word on pricing yet, but look for the new UP4 in stores this summer.
