Radio Frequency Identification

RFID 

What is RFID? Yes, that is the same question I had when I heard about it. Well, as it turns out RFID is a radio frequency identification used to store, read and transmit data located in RFID tags. Ok, so what is a RFID tag? An RFID tag is actually a device which contains a tiny chips and a radio antennas; these devices or tags can be attached to objects such as price tags, shipping labels, ID cards even livestock, cars and computers. These tags can only be read by RFID readers these readers read and transmit data to identify the object with the RFID tag. When an object with the tag is a within the range of the RFID reader , which ranges from two inches to about 300ft or more, it recognizes it and transmits the data in the tag. Each tag is unique and can be identified individually and also data can be updated as necessary. Today many companies and institutions use RFID technology to keep and track data necessary to conduct business, things such as inventory tracking, ticketing applications, mobile payments, package tracking, and even border security.
