What is RFID?
Radio Frequency and Identification (RFID) is an automatic identification method that uses radio waves to remotely read data from tags. The main advantage of RFID is the tag need not be in the line of sight of the reader.An RFID tag is a small object that can be attached to a product or item. It usually contains information about the product or a unique identification number. There can be two types of tags, active and passive. Passive tags require no internal power source, whereas active tags require a power source.
