Abstract
To allow teleshopping to be performed quickly and reliably via the television network, receivers (3) are equipped with smart card readers (4), and the transmitter (2) sends information which is processed in the smart cards by means of the viewers' control devices (6). The result of this process is displayed on the screen and communicated later to the transmitter. This result allows the viewers' reactions to be authenticated.
