RFID BASED SHOPPING TROLLEY
[attachment=22196]
Automatic Identification (Auto-ID) systems have become commonplace in access control and security applications, in industries requiring the tracking of products through the supply chain or manufacturing process, and in industries requiring the identification of products at the point of sale or point of service. Perhaps the most widely recognized Auto-ID system is the bar code system developed during the early 1970’s. More recently, Radio-Frequency Identification (RFID) systems have begun to find greater use in automatic identification applications.
Radio Frequency Identification (RFID) systems use radio frequency to identify, locate and track people, assets, and animals. RFID systems consist of Radio Frequency (RF) tags, or transponders, and RF tag readers, or transceivers. The transponders (tags) themselves typically consist of integrated circuits connected to an antenna. The use of silicon-based microchips enables a wide range of functionality to be integrated into the transponder. Typical functionality ranges from large read/write memories to integrated temperature sensors to encryption and access control functionality. The transceivers query the transponders for information stored on them. This information can range from static identification numbers to user written data to sensory data.
This project aims to develop a device that can be fitted in the shopping trolleys which reads the price of purchased items and displays the total amount in the LCD display attached to it. In the present situation, the customer has to stand in the long queue in the billing counters to know the total amount of purchased items. This process consumes much time and causes uneasiness to the customer. Also the customer cannot purchase the items based on the amount of money he has. The new system avoids the above difficulties by displaying the total amount of purchase when the item is put in the trolley and thereby the user can limit the purchase. This project is implemented using the innovative technology of Radio Frequency Identification (RFID) and Wireless communication. Each item in the shop will be provided with an RFID tag. This transponder (tag) stores the unique id number of the item and related information. The information consists of the item name, price details etc. When interrogated by a reader, it responds with that data over a radio frequency link. The readers are fixed in the shopping trolleys.
