Very interesting new product i saw last week (sorry for lagging and just now posting this)
It is called Geode icache, and the product has a few interesting features, it combines a fingerprint reader for authentication, a small e-ink screen to display barcodes for purchases, and finally a card you can use in case your vendor needs a mag strip method for purchasing.
Here is the link to the story: http://www.kickstarter.com/projects/1404403369/geode-from-icache?ref=live
I would love to hear your thoughts, so comment away!
here are a couple pictures i snagged:
