RFID stands for radio-frequency identification. RFID mifare ultralight cards are used for applications where tracking or identifying personnel is important or where access control is required. Various RFID frequency bands are utilized in cards today, including 125 kHz low frequency proximity, 13.56 MHz high frequency smart card and 860-960 MHz ultra-high frequency (UHF).
Proximity cards and smart cards are often referred to simply as "RFID cards." The type of RFID frequency band used depends on the application, factoring in security level, read range and data transfer speed requirements.
125 kHz (LF) - Common proximity card format used for employee badges and door and gate access control.
13.56 MHz (HF) - Higher security format used for credit cards and employee badges for physical and logical access control.
860-960 MHz (UHF) - UHF cards have a read range of up to 50 feet used for identification, access control and transaction processes.
