POS systems is a technology for financial transactions in retail establishments. For example, in a supermarket a POS system includes the hardware and software used for checkouts, or the computer equivalent age of a cash register. The most important difference between POS systems and cash register is communication. When a client
is processing a transaction at the supermarket, automatic response includes an update of the inventory. If necessary, repeat a command to replace the element is processed, the tax record is maintained, and the system of store management is informed.
The main component of POS systems is the computer. It is wise to use the POS computer for business transactions only, reports and inventory control, and isolate POS computer use from activities in general use. Use a separate web surfing. Computer software systems standardized two commonly used for OPOS and JavaPOS
Security is a problem for POS systems. Poorly implemented systems are one of the main causes compromising
credit card data. A well designed system will encrypt wireless transmissions, and not keep the entire tape, code
validation credit card or PIN. All traffic on sensitive public networks must be encrypted.
There are several subsets of point of sale systems, each of which is worthy of further study. Industry-specific POS
system packages is available for auto repair shops, beauty salons, pharmacists, cleaners and more.
The restaurant industry is well served by many POS systems different sales. Kitchen monitors are used to display
commands and manage the operation. Systems are often enhanced with wireless systems that enable communications. This allows servers to send customer orders to the kitchen from anywhere in the restaurant and can be used to make card transactions safer because credit credit card customer is never out of their sight.
A new trend in POS systems, particularly in supermarkets, is self-checkout. In a system of self-service, the customer scans the barcodes on individual items. In the case of a product, a scale is used, and the customer enters a code from a menu. Usually some kind of validation is used to compare the elements analyzed with the weight of the product.
Payment systems is similar to using an ATM. The advantages of this system include reduced overhead costs for
staff, and also reducing the time that the client should wait for your order. RFID (Radio Frequency Identification) is
a promising technology for self-checkout. With this technology, the POS process could eliminate reading
barcodes. Like RFID requires Line of Sight (LOS), the client can bag their purchases as they make their choice,
and no need to remove their items in the bag to make an inventory purchases to compile.
Integration of RFID readers in POS systems is not complicated. The interface is similar to a bar code reader.
Options include barcode readers, card readers, credit and receipt / invoice printers. POS systems are often
offered with modules integrated accounting and inventory control systems. Reports can be generated to include
sales, costs and profits per item, seller, category or time period.
The computer is a great tool for the retail industry. By replacing the cash register with a well implemented
computer system, significant improvements in the operation are possible.
