摘要

An arrangement for reading data recorded in infra-red on the surface of a card upon which may also be recorded a visual representation is disclosed. The reading apparatus comprises scanning means for scanning in the encoded fault tolerant digital form of the data on the surface, means for processing the scanned data and for decoding the data into a secondary digital format and means for outputting the secondary digital format to an output device with which the secondary digital format is usable. The output device presents the data in a human readable form. The data may include text and/or images equivalent to recording a book, newspaper, manual or a database.
