A Radio-frequency Identification (RFID) Tag is a device that can be applied to or incorporated into a product, animal, or person for the purpose of identification and tracking the tagged object using radio waves. An RFID Reader retrieves the identification and tracking information stored in the RFID tag. There are two types of RFID tags: passive RFID tags, which have no battery and convey information to the Reader by reflecting radio waves generated by the Reader, and active RFID tags, which contain a battery and can broadcast information to the Reader on their own power.
RFID Middleware is software that interfaces directly with RFID readers and printer/encoders, filters and formats the read data, and passes the data to a user application that uses the input to drive a decision or complete a transaction. Traditional RFID middleware also often offers some degree of device management, such as remote monitoring or configuration.
A typical use of RFID is in enterprise supply chain management to improve the efficiency of inventory tracking and management.
