These cards do not run Java, but CardJava. Yes the syntax may look similar at first glance, but it's a completely different beast with huge limitations. Then - an antenna for bluetooth, NFC and for wireless charging? Combine those and you'll have issues. NFC requires a very small amount of 'wireless power'. Charging a battery requires a more serious amount. Having fried more than one NFC card here at work, I know how tricky it is to work with wireless tech. Good luck managing that. There is no way this technology exists in the form-factor they're presenting or require. The dynamic magnetic stripe sure is possible, but not that small. You also seriously underestimate the cost of all this. For this to work, they need their own silicon - no way around that fact - which is very expensive, certainly because this is clearly not a product that many people will actually order. But from your pov, "just some more silicon" seems to be a walk in the park. I'm not aware of any e-ink displays avaiable with touch like they presented there. That would by the way need another separate controller. Oh look - more silicon! This entire picture is not just a "couple bucks". It contains technology you find in current phones at an even smaller scale, with a much smaller target audience. Really - who is going to pay 155 bucks simply to have a plastic card? To me it all looks like someone dreamed up an utopian payment solution for the US market and built a scam from it. It uses seriously outdated magnetic stripes which is irrelevant to most part of the world, and by the time it would actually be possible to make a stripped down version of this, hopefully NFC/EMV will have replaced this insecure mess and everybody will be paying with their phone. Anyway - keep an eye on Cartes on 4-6 November - which is THE fair for payment related technologies. If it's not there, it doesn't exist.
