Successfully introduced by major brands operating in the logistics and distribution sectors, the RFID system has brought many benefits to the entire production chain, from the purchase of raw materials to the final retail stage. Unlike the barcode, the RFID TAG has higher resistance to external agents: it does not need to be placed in a visible position to be read and can be updated by modifying its data. Its greatest advantage is that it cannot be duplicated. This ensures the full traceability and identification of each product.
The transponder can be produced in countless formats: inserted in labels such as for clothing, as a sticker applied on product cartons, or on cards that are the size of credit cards.
The reader emits an electromagnetic field generating a current in the tag that powers the chip.
The chip powered by the reader transmits all its information via an antenna to the card reader.
The IT system manages the transfer of data to and from the card reader.
The antenna contained in the tag receives a signal, which, by the principle of induction, generates a flow of electric current that feeds the chip. The tags transmit on different frequency bands, defined by ISO standards.
