​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.
