I remembered the only startup I'd ever backed called Plastc. It promoted a black credit card with an E-Ink display where the name and credit card number would normally be. The idea was a user could scan regular credit cards, loyalty cards, etc., into the memory of the Plastc card. So at check-out, the user would enter their pin and then select which card to pay with. They then swipe or insert the card and the data from the selected card is read into the machine. Not sure what happened to it, whether the company was mismanaged or if the product just wasn't viable, but it was such a cool ideas.
