A method of operating apparatus for value, the apparatus being connected to a telecommunications channel, includes the steps of transmitting a forward message from the apparatus to a remote location via the telecommunications channel; receiving a corresponding return message from the remote location via the telecommunications channel; verifying the return message to determine whether it is authentic; and, if so; permitting the operation of the apparatus; and, if not; inhibiting the operation of the apparatus. A method of charging for the operation of apparatus connected to a telecommunications channel is also disclosed including the steps of; receiving a forward message from the apparatus via the telecommunications channel; verifying the forward message to determine whether it corresponds to a predetermined apparatus; and, if so; transmitting a return message to the apparatus via the telecommunications channel; and generating a charge to an entity associated with the apparatus. |
