What Is RFID?
Radio-Frequency-Identification (RFID) is an identification technology transmitting between an electronic tag (TAG) attached to an object and containing information about that object and a receiver (READER) that identifies itself through the radio frequency. RFID is a system that can form a basic element of easy, fast, error-free data entry, storage and transmission in warehouses in markets and factories and information technology, shortly in every area where a dynamic data can be used or required. The significant issues related to the widespread use of technology are cost and privacy.
THE EFFECTS OF RFID
Information is written on RFID tags, and this information is read when needed by means of radio waves. Passive tags, the most widely used ones, are activated with energy emitted by the RFID reader and send the information on them. RFID readers transmit the information they collect from labels directly or via the network to the computer / software system that will process this information. This information is used or stored according to the operations desired by the user, the same as happens in the barcode systems. Although RFID applications seem costly compared to other applications, according to their functional and cost analysis, they are much more profitable than their counterparts for technological follow-up.
