David Bruno and Tom Seymour's Oyster card wallet concept design uses an LED display on the wallet's surface to show the user's transit card balance. The Oyster card is London's transit card and is used on a number of different travel systems across London.

The Oyster card wallet would make it easy for commuters to know their account balance so they wouldn't show up at the gate only to find that their balance is at zero.
