A non-contacting transaction system for ticketing is described which consists of a hand-held transmitter (10) which contains information unique to the user and which, when actuated by the user, generates a wireless signal which is picked up by a receiver (12). In a preferred arrangement, the transmitter (10) contains the user's code and has a keypad (17) for the user to insert a personal identification number (PIN) code. This PIN might be a series of digits or the owners telephone number, car registration number o r any code preferred by the owner. The detectors of the receiver are coupled via a transmission line to a local system where the user's code and PIN number and details of the purchase, received from the vendor, are registered against the user's number so that billing can be carried out subsequently. The local system can include a means for checking and for rectifying the correctness of the code and PIN number prior to transmitting the data via the modem to the central system. The device is flexible and the PIN number could be required for all transactions to minimize fraud. Each transmitter may be provided with a terminal to allow an input to the memory for changing details of the user's account and charge number. |
