Essex Libraries introduce key fob membership card (UK)

"New library users in Essex are to be issued with 'fob' devices alongside traditional membership cards, under a new scheme to modernise Essex's book service. The fobs, designed to fit onto key rings, work in the same way as library cards and can be scanned whenever a person checks out or returns a book, CD or DVD. Existing library members can request one of the devices at any of the county's libraries"
