Radio frequency identification (RFID) uses electromagnetic frequencies to identify markers that can be attached to the item or to put in it. These tags can contain any unique data to which access manufacturer, financial institution or retail store needs during the scan of the object. This is very similar to the system barcodes , but offers a higher level of security. Because of this, many industry refuses to use the identification system for bar codes and instead focuses on the implementation of RFID. These RFID tags can be smaller than a grain of rice, and they are more resistant to accidental damage.

The RFID reader has two main components, the transmitter-receiver for radio transmission and the antenna for its reception. When the transceiver sends a radio signal to the marker, the marker aktiviziruyutsya. Activated marker passes all the information contained in it, which raises the reader through its antenna.

Credit cards use RFID in the form of EMV chips , which are the gold, square chips in many recently released maps. When a credit card with EMV chip card inserted in a terminal, the broadcast occurs within milliseconds ; the disclosure of all information necessary to complete the transaction.
