2.9 inch Inventory Patrol E-ink Tag Wireless Dynamic QR Code Electronic Label

The SETPB0290N_XG is a 2.9-inch inventory patrol e-ink tag specifically designed for equipment inspection, patrol check-in, and on-site verification.

By utilizing dynamic QR code technology, this device effectively prevents inspection fraud and ensures that patrol personnel must be physically present at the inspection location.

The label supports automatic dynamic QR code generation for inspection and patrol applications. As time changes, the system automatically regenerates a new QR code at a preset interval, ensuring each scan is unique and time-sensitive.

The dynamic QR code mechanism is designed to eliminate inspection cheating. Only personnel who arrive at the actual inspection point can scan the current QR code and complete the patrol check-in, ensuring authentic, traceable inspection records.

The label supports remaining battery level indication, allowing operators to monitor power status and plan battery replacement proactively.

With an e-paper display that consumes power only during refresh, the device is optimized for long-term deployment. The standby time is not less than 18 months.

The device supports time synchronization via mobile App. After battery replacement, users can perform a one-time time sync through the App, ensuring accurate QR code updates without manual calibration.
