Applications 1. Supermarkets: - The use of RFID system assists in better inventory management and enhances customer shopping experience. The RFID system can indicate the type of clothing selling faster or slower, which provide customized advertisement on picked clothes according to the RFID tags. 2. Library: - The RFID tag is programmed with identification and security information and then affixed to books or library materials. When used in conjunction with RFID readers, RFID tags can be read at a distance to identify marked items or to detect the tag's security status. 3. Golf Cart: -As vehicles move into or out of a zone, the fixed RFID readers report the movement to the vehicle tracking system. As vehicles are parked within a zone, the personnel scan the RFID tag with the handheld, capturing both the RFID tag ID and the GPS location, which provides the vehicle tracking system with the exact location of the vehicle within the zone. Any vehicle can be located in mere seconds using the software. 4. Shopping mall: -All the products in the mall will be equipped with RFID tags. When a person puts any products in the trolley, its code will be detected and the price of those products will be stored in memory, its name and cost will be displayed on LCD and will be sent to billing Counter by wireless modules. Comparison Existing System Proposed System Person required to scan the barcode on the product. Automatic sense of RFID tag from product. Line of sight is required for scanning the barcode. No line of sight is required to browse RFID tag. Barcode should be visible on the surface of RFID is placed within the merchandise. product. Short reading space. Long reading space. Readability of barcode is impaired by dirt, moisture, abrasion, or packaging. RFID tags don’t seem to be laid low with such conditions. Barcode doesn’t have a scan and write capability. RFID tag have browse and write capability. Need to pull the trolley. Doesn’t have to pull the trolley. Automatic trolley. Ask the staff about the offer and other details regarding the product. All the details about product are displayed on screen automatically. Doesn’t resolve the problem of antitheft. Resolve the problem of antitheft. Future scope A GPS tracker for tracking the trolley, also the internet facility to use for delivery and also driverless transportation. Personal trolley (adding webcam and using image processing we can make the trolley follow the specific person around). The RFID system which can scan multiple tags at a time with 100% accuracy is still under development. In future it can be also used in hotels and restaurants. Robotic arm can be used for picking and dropping products. There can be voce assistance module to make the trolley more advances.
