MasterCard is envisioning a future of ubiquitous payments, where practically every device has the ability to pay for things at contactless terminals. The credit card company unveiled a new program today with precisely that goal, and it has also lined up a bunch of early partners, including GM and wearable companies Nymi and Ringly. It also looks like MasterCard isn't just looking at typical gadgets -- it even wants payments in things like fashion accessories (designer Adam Selman is another launch partner). It's not hard to see why MasterCard is making this push. Seamless payments are convenient for customers, but it's also essential for MasterCard to gain a foothold in the post-credit card era. And smaller companies will likely need some help if they want to integrate payments (Jawbone, for example, teamed up with American Express for the Up4).
