The technology featured in two interviews hosted by mytreo.net is nothing new. Cards that let you pay with virtual currency just by being near a sensor have been used in places like Singapore for some time now. It was obvious that Mastercard and visa would look to integrate digital credit with smartphones and PDAs, since more and more people are buying them.

But these videos are still great because they clearly show that both credit card companies are serious about this. It's even clearer that paying with our mobiles and handhelds is an inevitability. Not to mention video is always a great way to see stuff in action.
