An interactive system in which information read from two or more tags ( 10, 12 or 10, 12' ) jointly determines a process to be carried out. One of the tags may identify a user by for example his/her store loyalty card number or by a personal identifying tag (or card) in a cordless RF terminal and the other of the tags may be a RF-ID tag storing details of an action to be performed such as the number of credit points to be given to the loyalty card in response to a transaction or provide promotional information to the user. The process may comprise issuing a command to an action server ( 28, 30 ) to provide, or instruct the sending of, output information to a user, by for example over a radio link to a cellular telephone apparatus ( 18, 34, 36 ) or PDA, or displayed to the user on a video display unit ( 38 ).
