Which technology is commonly used in wireless access control systems?

In wireless access control systems, Bluetooth technology is widely utilized due to its capability to establish a secure, short-range communication between devices. It allows for seamless connections, making it particularly effective for scenarios like mobile credentialing where individuals can unlock doors or gain access with their smartphones or BLE-enabled devices.

Bluetooth's low energy consumption also enhances its suitability for battery-powered devices, supporting longer operational life and reducing maintenance needs. This technology facilitates a balance between security and convenience by providing encrypted connections, which is essential in access control systems to prevent unauthorized access.

While other technologies such as RFID, Wi-Fi, and Infrared can also be used in various access control applications, Bluetooth stands out for its specific advantages in wireless environments, particularly where user convenience and mobile access are priorities. RFID is more commonly associated with card-based systems, Wi-Fi can be less energy-efficient, and infrared works primarily in line-of-sight scenarios, making them less ideal for many modern wireless access control applications.
