ABSTRACT:
An electronic token for use with a prepayment commodity meter such as an electricity meter comprises a key-like device 10 having a head 12 containing an electronic circuit and a body portion 14 for insertion into a keyway in a receptable 40 in the meter. The body portion 14 has grooves 24 which serve to guide the body portion into the keyway, and which contain electrical contacts 28, 30 connected within the device 10 to the electronic circuit. Between the body portion 14 and the head 12, the device 10 is provided with a locating recess 27, which engages a projection 78 in the receptacle 40 when the body portion is fully inserted into the keyway. The receptacle 40 incorporates a combined shutter 98 and spring 102, which serve to close the keyway in the absence of the device 10, and to urge the body portion 12 to one side of the keyway during insertion, such that the recess 27 engages the projection 78 and the contacts 28, 30 engage contacts 68, 72 in the receptacle.
