V68 QR code scanner module is an area imaging engine optimized for mobile payment codes. The V68 embedded barcode module is only used for reading mobile phone screen codes and scanning codes from a distance of 1 meter. V68 does not use a laser light source, only LEDs as decoding indicator lights. The wavelength range and luminous intensity generated by these LEDs under normal usage are safe. Many customers like this remote scanning module. They installed it on a self-service machine, and the iPhone can achieve long-distance scanning of 1-1.5 meters.
