In order to facilitate product traceability, the manufacturer will burn the QR code on the product by means of laser engraving or laser coding. Due to the different shapes of the products, for example, the flashlight laser coding is a QR code engraved on the curved appearance, and The flashlight has different colors and reflective materials, which requires very high requirements for the handheld barcode scanner.

The XT6201B developed and produced by Shenzhen Xingtong IOT can scan such laser codes and DPM codes very well.
