Abstract
Abstract A Point-Of-Sales (POS) data system includes one or more controllers (100-0; 100-1) at a management centre in a store and a plurality of POS terminals (1-0; 1-1;... 1-n) provided at sales counters in the store, the controller and each POS terminal being interconnected by a closed circuit (L). The controller includes a price look-up unit (PLUU) which includes a price look-up (PLU) memory (M 1) which contains a PLU file comprising a PLU table and a sum table corresponding to the PLU table. When the PLU table is searched by a PLU inquiry signal having an article code designated by a POS terminal, the sum table is correspondingly accessed, based on corresponding address information for the PLU table and the sum table.
