The present invention relates to a POS system and a method for driving the same.
A POS (Point of Sales System) generally means a sale point management system which has a cash receipt and payment registration function and a computer function. For example, the Korean Patent Publication No. 2004-0087586 describes an ordinary POS system.
When such a POS system is used, it is possible to recognize the sale flow of goods by basic items and recognize in details a sale trend and a sold time of new goods and promotion goods as well as a sale trend of poor sale goods, analogous goods or competing goods. A marketing strategy such as a correlation between a sale price and a sale quantity, a key marketing target, an advertisement planning, etc. can be therefore effectively established. In addition, a goods management system such as an inventory, an ordering, a delivery, etc. can be simplified and standardized, which contributes to the saving of prime cost.
Therefore, most of the shops or stores which make profits by selling goods are using such a POS system.
The above-described POS system comprises a database server which is generally configured to perform a goods management, a sale management, etc., and a POS terminal which performs a variety of POS functions in cooperation with a server which supports the POS functions like the server of the VAN (Value Add Network) company which has a function for credit card payment. Here, the POS function comprises a function for collecting and processing a variety of information and data which are necessary for the sake of a goods management, a payment process, a sale amount calculation process and a shop and a store administration.
