A communication system comprises a card (10) (having generally the same dimensions as a credit card) and a reader/programmer (14). The card carries audio and/or visual data messages that are read by the reader/programmer and reproduced audibly and/or visually as required. The data messages are transferred by presenting the card to the reader via electrical contacts (13) and (15). In use, the data messages are typically for advertising and promotion of products, or for instruction or educational use. However, embodiments of the invention can be applied to fulfil a wide range of applications. The reader/programmer (14) can be arranged for example to transfer audio and/or visual messages to the card (10) (from an external source such as a personal computer or the Internet) and the card (10) then used to carry the message, by mail say, to another user who uses his own reader/programmer to interpret the message data. |
