ACCOUNTING METHODS AND SYSTEMS EMPLOYING NON-PREDICTABLE BAR CODES

摘要

An accounting system includes a point of sale terminal (20) to print a transaction receipt (26) having a nonpredictable bar code (36) and human-readable transaction information (34) based upon the transaction data. The point of sale terminal (20) communicates the transaction information to a transaction information system. The transaction information is downloaded from the transaction information system by reading the nonpredictable bar code (36) with a data reader (54).
