For some electronic materials such as IC trays, a barcode label has multi-standard dense small barcodes or QR codes and PDF417 codes. We only need to scan one of the barcodes when we carry out storage and inventory, so how do we choose the barcode? As for guns, let’s answer them separately below:

If you only have 1D barcodes, you can choose a laser scanning gun. The light from this scanning gun is a red laser line, which can clearly shine on the barcode to be scanned, so that there will be no mistakes, and the price is not expensive, such as XT6101 .

However, if you need to scan a QR code in addition to a QR code, or even a bar code on a computer screen, you need to choose a QR code scanner. However, because the QR code scanner uses CMOS imaging technology, the output is a piece of light. There is no way to only take a photo on a certain barcode that needs to be scanned. When there are multiple barcodes, it will scan any barcode. At this time, you can choose a wireless scanner such as XT3001ER or XT6400C. These scanners are all With specific settings, you can only scan the information of the barcode where the cursor is located, which solves the problem of scanning both the one-dimensional code and the two-dimensional code without messy scanning.
