Smart electronic door locks are gaining popularity in government, commercial, enterprise, and residential buildings as part of smart city initiatives. These locks feature Bluetooth® Low Energy (LE) connection to smartphones for convenient lock/unlock operations and Near Field Communication (NFC) based credential exchange. They also establish an IoT connection to a central PC for centralized access control and monitoring. Another notable innovation is the hassle-free and contactless charging of the integrated battery through NFC-WLC wireless charging technology.

System Benefits:

  • Wire-free and effortless installation, powered by an integrated battery charged via NFC-WLC technology
  • Exceptional security features include:
    • Secure Bluetooth pairing facilitated by NFC
    • Utilizes Bluetooth 5 and NFC communication
  • Boasts ultra-low power design with a minimal bill of materials (BOM)
  • Offers centralized control and tracking capabilities, such as approval of Bluetooth keys, through an optional IoT backbone (requires an additional router)
  • Optionally designed to meet IP67 dust and waterproof standards




  • Commercial, residential, educational, government, and industrial buildings requiring access control and monitoring
