ABSTRACT:
A micro-bar code data processing system is capable of reducing the number of digits to be expressed by the micro-bar code by compressing information to be contained therein. The micro-bar code data processing system includes a receiver for receiving an original data to be contained in a micro-bar code; a reducer for reducing the number of digits of the original data by compressing the received original data; a converter for converting the compressed data into an encoded micro-bar code data; an outputter for outputting the encoded micro-bar code data; a receiver for receiving encoded data contained in the micro-bar code; a converter for converting the received encoded data into a compressed data; a restorer for restoring the original data from the compressed data by decompression of the compressed data, and an outputter for outputting the restored original data. With such a construction, the number of digits of the data can be reduced by compression of the original data so that the required length of the bar code can be shortened.
