Abstract
In one preferred embodiment, a memory device for insertion and retention in a hole defined in a planar identification card having upper and lower surfaces, the memory device comprising: electronic circuitry disposed in a cylindrical housing having upper and lower surfaces; the housing being held substantially within the hole after being snapped thereinto; and the housing having a total height substantially the same as the thickness of the card. In a further aspect of the invention, electronic circuitry in the housing is accessible by temporary attachment to an electronic terminal, the electronic circuitry being powered by a charged capacitor, the capacitor being adapted to be charged by the terminal with a charge sufficient to power the electronic circuitry for only a selected period of time. The capacitor may be charged over a communication line to the memory device. The memory may be disabled if a use limitation stored therein is exceeded.
