We said paying for stuff with other wearables other than smartwatches would grow in 2016 in our Wareable 50, and MasterCard has signalled its intent to make this a reality by announcing a partnership with Coin that lets you grab a bottle of water on your run, sans wallet.
While you will have no doubt heard of MasterCard, Coin is a company that's being working on slimming down your wallet with one single card-like device that uses Bluetooth and has NFC tech to enable tap-to-pay to make contactless payments.
The partnership will work with Coin bringing its hardware and software expertise to the table with MasterCard providing its own digital enable service to help bring everything all together.

The first devices to benefit from the partnership have already been revealed and include our 2015 fitness tracker of the year Moov, Atlas Wearables, who make a pretty impressive gym-focused fitness tracker ,and Omate, a company that hit Indiegogo recently with its 3G-enabled Omate Rise watch.
Right now, payments from fitness trackers are pretty rare. The Microsoft Band 2 will let you buy a cup of coffee in Starbucks and the Jawbone UP4 enables mobile payments for American Express Card members.
With Samsung Pay set to spread to more countries this year and Apple Pay's presence continuing to grow, it's going be a big year for ditching the wallet.
How we test

He also regularly contributed to T3 magazine when they needed someone to talk about fitness trackers, running watches, headphones, tablets, and phones.
