The frequency of an RFID door lock can vary depending on the specific system and technology used. The most commonly used frequencies for RFID door locks are 125 kHz, 13.56 MHz, and 900 MHz.
125 kHz is a low frequency that is commonly used for proximity card systems. These systems typically have a shorter range, typically a few inches to a few feet, and are often used for access control and security.
13.56 MHz is a high frequency that is commonly used for contactless smart card systems. These systems typically have a longer range than proximity card systems, usually up to several feet, and can be used for a wider range of applications, including payment systems and public transportation.
900 MHz is an ultra-high frequency that is sometimes used for long-range RFID systems, such as vehicle tracking and toll collection. These systems can have a range of several yards or more, and are often used for applications where it is not practical or safe to have physical contact with the RFID reader.
2.45 GHz: This frequency is used for RFID systems that require a high read rate and high data transfer rates, such as in manufacturing and supply chain management. The high frequency allows for quick and efficient scanning of large volumes of items.
5.8 GHz: This frequency is used for short-range RFID systems, typically for tracking items within a few inches. It is often used in manufacturing and assembly line applications.
It's worth noting that there are many different RFID standards and protocols that can operate at the same frequency. The specific frequency and protocol used will depend on the requirements of the application and the available hardware.
