125 kHz RFID cards are low-frequency (LF) proximity cards used for basic identification and access control applications. They provide reliable short-range communication and are widely used in legacy and simple access systems.
These cards are compatible with RFID readers supporting 125 kHz low-frequency proximity technology.
13.56 MHz RFID cards are contactless smart cards commonly used for secure identification, access control, and automation systems. These cards operate using high-frequency (HF) RFID technology and are widely used in building management, industrial control systems, and smart card applications.
Typical standards include ISO/IEC 14443 and ISO/IEC 15693.
These cards are compatible with RFID readers supporting 13.56 MHz HF technology.
