Whats the most popular iButton accessory?
Nearly 2 million public transit passengers in Istanbul carry their iButton on a plastic key fob. It’s the simplest way to mount an iButton for applications that require only momentary contact. After snapping in the iButton, the fob can be attached to a key ring. Fob types vary to fit the depth of the iButton they will carry and offer the choice of angled or straight shapes.
