QR Code Attendance vs Bluetooth (BLE) Beacon Attendance

Quick answer

Bluetooth Low Energy (BLE) beacons broadcast radio signals to detect nearby employee phones, but suffer from significant operational flaws: radio signals bleed through walls into parking lots (allowing workers to clock in from their cars), beacon coin-cell batteries silently die every 6-12 months, and mobile operating systems frequently kill background Bluetooth scanning. Free QR Attendance uses visual camera scanning, which works instantly with 100% boundary accuracy and zero battery hardware to maintain.
