Charbax has turned up another neat little gadget at IFA. He stopped by the E-ink booth and got Sriram Peruvemba to demonstrate E-ink's latest product.It's a complete battery+screen+chip solution that can be embedded in a standard credit card. It runs on a battery that should last 2 years, and is shipping right now.It's designed to generate a 1-use key each time you use it. There's a number of existing security tools like this now (Paypal have one), and the idea is that the single use PIN reduces the risk that someone might memorize the security info when they copy your card.
The difference between E-ink's solution and the other products is that the others are all a separate object. Paypal, for example, mounted theirs on a keychain (it's about the size of a small flash drive). E-ink's solution removes the need to carry around a second object.
Right now it's mainly used in banking and other high security industries, but there's no reason why it can't be used as a credit card.
Nate Hoffelder is the founder and editor of The Digital Reader:"I've been into reading ebooks since forever, but I only got my first ereader in July 2007. Everything quickly spiraled out of control from there. Before I started this blog in January 2010 I covered ebooks, ebook readers, and digital publishing for about 2 years as a part of MobileRead Forums. It's a great community, and being a member is a joy. But I thought I could make something out of how I covered the news for MobileRead, so I started this blog."
