Imagine a shopping trolley in a self-service store equipped with a scanner and a touch-screen computer. You scan the goods, put them in the cart, and the computer gives information on each of the goods and offers additional purchases. The computer constantly shows the amount of the cost of the selected goods, so that you know every minute how much you will spend. Having finished choosing purchases, you go to the self-checkout or cashier. Since the amount of your purchases is already known, and all of them are packed, the waiting time is minimal. You just have to pay for your purchases.
An innovation that provides such a shopping trip is called RFID (Radio Frequency Identification) technology. RFID helps retailers around the world meet the needs of the most demanding customers and thus increase sales. This technology is gradually changing the retail industry, providing sellers with information on the status and movement of goods in real time, increasing warehouse productivity and preventing losses. Many of the world's leading retailers have planned the introduction of RFID technology. This move will affect more than 200,000 manufacturing enterprises and suppliers and direct the global hardware and software market to support RFID.
