Encoded medical data are made available to a mobile unit/terminal via a central server in a network. A request is sent to the central server; encoded medical data are generated in the server; encrypted data are transmitted from the server to the mobile unit/terminal, after authentication by a user; the encoded information is stored and protected in the mobile unit/terminal; upon authentication by a user, encoded information is sent to the server for decoding; and a picture containing user-readable text is sent to the mobile unit/terminal.
