Dedicated UV sunken barcode printer

To test the device's UV barcode scanning capabilities, we use a dedicated UV barcode printer to create some types of UV sunken bar codes of type 1D, 2D and QR codes …. According to the manufacturer , CMOS sensor on this barcode scanner is upgraded from OPN-3002i version. In the actual experience, the UV barcodes we printed for testing were identified almost immediately without any problems.

In addition to UV barcodes, it is also capable of scanning all common 1D and 2D bar codes on materials from boxes, plastic paper bags, reflective labels to curved section objects. like potions, candy, ballpoint pens. Fast scanning speed, almost immediately when the object is placed in the projection area, the machine has finished reading and sound feedback. It can also scan codes in low light or no light (dark) due to the built-in CMOS sensor and built-in LED system.

It can scan well in low light conditions

The OPN-3002n UV can also quickly and accurately read codes on the phone and computer screens in the form of photos and codes integrated in the application or downloaded images. However, in low light conditions, the speed of scanning UV barcodes is a bit slower than the usual new codes. This is due to the fact that UV codes are often imprinted on glossy materials so the code recognition speed will be more difficult.
