Abstract
A mobile telephone includes a control device, which comprises a receiver to receive an enabling signal and a controller to enable operation of the mobile telephone in dependence upon the enabling signal. An active badge transmits the enabling signal. If the telephone and the badge are separated and the mobile telephone is no longer able to receive the enabling signal, then the controller disables the mobile telephone.
