SMART SHOPPING USING QR CODE AND RFID SYSTEM

RFID generally encompasses any wireless (or partially wireless) communication that allows for remote retrieval of information associated with a particular commodity, product, component, or other item. In RFID environments, each suitable item is tagged with an RFID tag that includes and (actively or passively) transmits one or more pieces of information including, for example, a unique identifier and such. These pieces of information are requested or retrieved by an RFID reader. Moreover, the RFID often must be manually docked or interfaced with a port such that the collected RFID information can be processed. In many circumstances, RFID technology allows the two devices (the tag and reader) to communicate with one another while not maintaining a line-of-sight in various weather conditions. Extensive research has been carried out on vision based automatic identification technology that recognizes images codes using smart phones to provide various services that can recognize the authenticity of any product We are using Multiplexing and De multiplexing algorithm for recognizing QR code image using smart phones to provide various services that can recognize the authenticity of any product.
