The mbracelet

The mbracelet, developed by Studio 5050, is a wrist accessory capable of withdrawing money from prototype ATM machines.


The mbracelet stores, shares and collects information. It has 3 slots that can receive interchangeable iButtons to enable the wearer to customize the information they want to carry with them.

The device has a grid of tri-color LEDs. When the mbracelet is connected to a host unit the grid displays an animation to inform the user that contact has been successfully made. Users can activate a customized color animation on the LED display that changes depending on hand motion.

The mbracelet’s “plug” interface allows wearers to transfer messages to each other by performing a cross handshake. When the two “plugs” mate, the mbracelets poll each other and messages are transferred automatically.
