A terminal unit, to which commodity information is input, processes the input commodity information. The terminal unit includes a first conversion unit for converting transaction information including at least the input commodity information into information corresponding to a high density bar code, the transaction information being information regarding the transaction of one or a plurality of commodities, and a bar code printing unit for printing the high density bar code on a sheet based on the information obtained by the first conversion unit. The terminal unit may further includes a reading unit for optically reading the high density bar code, printed on the recording sheet, representing the transaction information and for outputting the transaction information represented by the bar code, the transaction information being processed by the terminal unit.

SYSTEM AND METHOD OF OPERATION OF HOST AND TERMINAL UNIT HAVING FUNCTION FOR CONVERTING TRANSACTION AND COMMODITY INFORMATION INTO BAR CODE FOR PRINTING ON JOURNALS AND RECEIPTS AND READING THEREFORM FOR INPUT TO SYSTEM

A terminal unit processes commodity information relating to each of one or more commodities involved in a transaction and transaction information defining the transaction. The terminal unit includes a first conversion unit for converting the transaction information for a transaction, including at least the input commodity information for each commodity involved in the transaction, into a corresponding high density bar code pattern which is supplied to a printer which prints the corresponding high density bar code pattern on a recording sheet. A bar code reader optically reads the high density bar code pattern, printed on the recording sheet, and outputs the corresponding transaction and related commodity information for processing by the terminal unit. The bar code reader distinguishes between a first bar code pattern read from the commodity and a second, higher density bar code pattern printed on and read from a recording sheet.
