It is widely used for contact identification (badges, cards …), traceability, production line, library, industry … The exchange of data between the reader and the tag is done in the neighborhood (a few centimeters) .
BF: Means “Low frequencies”. In RFID, there are two frequencies for the BF, 125KHz and 134.2KHz, known as ISO 18000-2 both of these frequencies are widely used for chip readers to identify domestic and farm animals, they are also used to access control (badges, cards …). The exchange of data between the reader and the tag is made on contact.
