Key Fob Transponder KF11 PVC

Key Fob Transponder KF11 PVC

B-Id's low-cost, waterdrop-shaped key fob model KF11 is an interesting alternative to conventional RFID key fobs. Unlike the KF10, the housing of the new model is not made of the fibreglass FR4, but of PVC.

This change makes it cheaper than the KF10, furthermore the KF11 is also available in five colours (white, red, yellow, blue, and grey) for small order quantities. The flat and simple design of the new key ring makes it elegant and easy to transport.
