"Coin is a connected device that can hold and behave like the cards you already carry. Coin works with your debit cards, credit cards, gift cards, loyalty cards and membership cards. Instead of carrying several cards you carry one Coin. Multiple accounts and information all in one place."
Jim Lerman's insight:
I don't usually include commercial products, but this seems exceptionally practical. Pre-order available for $50. Goes to $100 later. Supposed to ship in summer 2014. Seems a bit pricey, but oh, so cool.
Watch the video; that's cool too.
