Samsung and Visa join forces to enable NFC mobile payment at 2012 Olympics

<img alt="" border="1" hspace="4" src="http://img819.imageshack.us/img819/7830/samsungvisa04012011.jpg" vspace="4">From a gadgeteer's point of view, one of the best things about the Olympics is its tendency to bring in new technologies to the hosting city. Take the 2012 games, for example: not only are the London Underground stations getting WiFi hotspots, but news has it that Samsung and Visa are holding hands to deliver NFC mobile payment solutions to the city. In fact, more than 60,000 locations in London are already geared up with contactless payment systems, and right now Visa is negotiating with banks to get its contactless cards and mobile phones approved. For the latter, one such device will be Samsung's Olympic and Paralympic Games mobile handset that comes with a Visa-enabled SIM card, and it'll be made available to sponsored athletes as well as various retailers. Furthermore, this alliance will continue after the Olympics, and Visa is rolling out its mobile payment system in many other countries as we speak, so it shouldn't be long before we hear more Visa handset announcements. <a href="http://www.engadget.com/2011/04/01/samsung-and-visa-join-forces-to-enable-nfc-mobile-payment-at-201/" rel="nofollow" target="_blank">via</A>
