Bluetooth is a technology standard for the short-range wireless interconnection of mobile phones, computers, and other electronic devices. One type of Bluetooth technology that consumes significantly less power is called Bluetooth Low Energy (BLE). This type of Bluetooth remains in sleep mode unless a connection is initiated, which translates to much longer battery life. This is ideal for access control systems since it doesn't use as much power. BLE is the wireless technology used in mobile app-based access credential systems.

Even if your employees use the correct credentials to gain access to restricted areas, holding or propping the door open can create a security risk. This is why Door Held Open Alerts were created. This feature is part of an advanced physical access control system.
