::Sigh:: It sounds exciting.. but so did/do all the others trying to do the same or similar things. Unfortunately, banking regulations and reluctance to push technological boundaries at the risk of being liable or losing money are the big hurdles to clear here. Another slightly smaller hurdle is being able to design a product that is high enough quality and durable enough to survive without costing way too much. The first one I ever heard about was back in 1999, PocketVault from Chameleon Networks. They lingered with a website that was updated every couple of years promising a release soon. Next came the iCache. That one did a Kickstarter and actually made it out to market... sorta. I have one, but the company ran into huge manufacturing issues and folded under very odd circumstances. A few others I've kept an eye on are: Dynamics, Inc. Card 2.0 -- Was supposed to come out with exactly this product.. ended up doing a very reduced feature set that lets you just select A or B rewards. Protean Echo -- Same concept. Originally promised 2013 but recently updated saying they weren't ready yet. There was another that was a similar concept company/site, but I can't find a link to it or remember the name at the moment. :/ There is also a recent company that had a successful Kickstarter: Loop. Rather than a programmable credit card, they are hacking the magnetic readers themselves by making a mobile phone case or dongle that emits a magnetic field that tricks the reader into registering a card swipe. Pretty neat stuff to compete with the struggling NFC solution, but unfortunately, it isn't 100% compatible with all swipe readers, and totally incompatible with dip readers.
