Abstract
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.
