Now this new little invention is pretty handy! The UP4 is the newest addition to the Jawbone family, and boy has it made an entrance. The UP4 tracks all fitness, activity and heart data as the other Jawbone trackers do, but in addition to all that you can use the UP4 to pay for your shopping while you’re on the go as it links with your credit card. That’s right, when you’re out and about everything you need is right at your fingertips (well, wrist) and we couldn’t be more impressed! Need a cool beverage after that intense run? No worries, pay with your UP4.
So, you are probably wondering how it actually works? Well if you are an American Express cardholder you can simply connect your card to your Jawbone using the UP application. From there log all your usual Amex details (which, by the way, Jawbone does not have access to, so security is the same as using your card in a store). And tap away - you don’t need your smartphone, you don’t need to press any buttons…just a simple tap.
