Abstract
A smart card, a non-passive, secure, microprocessor based data storage medium, is used for the storage of a plurality of data messages and is read by a video telephone terminal equipped with a smart card reader to provide transmission of a data message, comprising video image data, either in still frame or full motion format, to a remote video telephone terminal. The use of the smart card for storage of a data message provides a secure, transportable message that is available for transmission from any video telephone terminal having smart card reading capability.
