Data storage and communication system for public use - uses pre-recorded memories available to public and containing various data read when memory is plugged into microprocessor based reader

摘要

The system is used for data which is periodically accessed by the public, such as tourism, leisure, and day by day information such as transport timetables. The data storage system includes a set of memories (1) which can be periodically obtained from set locations. The memories are pre-loaded with data which is correct for a set period. The associated data reader (3) comprises an enclosure (4) containing a socket (5,6) for the output connector; and a microprocessor which reads the data (8) and delivers data to a second set of terminals (12) which couple to a, pref. liquid crystal, display panel (10). A rechargeable battery (15) is mounted on the board containing the microprocessor and its display.
