RFID Systems

RFID systems consist of numerous specialized components, such as tags, rfid readers, edge servers, middle ware, and software. An RFID system allows for data to be transmitted from the tag to the reader, which in turn processes it for a particular use. The data sent can include identification, location information, price, color, and date of purchase. Radio Frequency Identification systems can also be employed for tracking purposes, which some point out as an invasion of privacy.

An RFID system works in stages. Items are equipped with a tag, which has a transponder that is assigned a unique electronic product code. The accompanying antenna has a transceiver and a decoder, which emits a signal and activates the tag. Once activated, data can be read and written to the tag. If a reader is in range, it decodes the data being transmitted by the tag’s computer and relays it to a host computer for processing.
