ABSTRACT:
A system and apparatus for compressing a binary data message generated by a digital input device is disclosed wherein a data message generated in a data terminal device as part of a merchandise transaction is examined on the basis of information content with all data relating to redundant information previously generated or known being deleted together with encoding of preselected portions of the non-redundant data results in the compression of the data to a minimum amount without losing the informational content of the original data thereby allowing the compressed data to be stored in a relatively small storage unit located in the data terminal device. A compressed data record is generated including an encoded start of record character which may signify, in addition to the start of the compressed data record, the type of merchandise transaction being processed. Other non-redundant data which can be determined by knowing the corresponding data of a previous data message are also deleted with only that data required in order to reconstruct the original data generated being retained in the storage unit.
