For those who have been in contact with barcode scanning equipment, I believe that they are no longer familiar with barcode scanning guns. They are basically used in the barcode payment industry. From a deeper level, its work mainly depends on the barcode reading engine embedded in the scanner, that is, the QR code scanning module. The type and type of the barcode reading engine embedded in the barcode scanner determines its use and application industry. Therefore, the selection of QR code reading engines in different application fields for scanner manufacturers is also different, but there are A common feature is that the size of the scanner itself is limited, and the two-dimensional code scanning head must be compact. Next, it will introduce in detail from its industry use how to choose a barcode scanning module?
Suitable for barcode reading engine embedded in 2D barcode scanner?
1. Two-dimensional code reading module that can scan the payment code on the screen
This type of barcode scanner is mainly used in payment fields such as supermarket and retail. It is not difficult to consider that such an embedded QR code scanning module must have a good readability of the mobile phone screen code, mainly scanning Alipay and WeChat payment 2D The distance for reading the barcode is about 5cm ~ 10cm. Generally speaking, the red light CCD two-dimensional code scanning module is used. Here I recommend the LV3096 two-dimensional code scanning module, the size is 21 * 14 * 11 (length * width * height), the volume is only 5g and its lightweight, not only can scan the screen code, but also easy for product labels and paper barcodes. Reading; IP54 industrial grade dustproof and waterproof design, the compression performance is very high.

2. One-dimensional code reading module that mainly scans paper
It is mainly used for scanning one-dimensional codes in the fields of warehousing, logistics, express delivery and office automation, such as scanning the one-dimensional barcode on the packing surface and the one-dimensional code on the driver's license. If you do not need to scan a two-dimensional code at all, consider the cost to choose a one-dimensional red CCD bar code scanning module to meet, such as LV1000R, LV12, LV14, FM100, etc. is a good choice; if some need to scan two-dimensional Code, then you must choose a two-dimensional code scanning module, such as LV3096, LV3296, etc. For the requirements of precise laser positioning, you can also choose LV3396.

3. High-density laser two-dimensional code scanning module for scanning irregular barcode surfaces
Compared with the red light scanning module, the price of this type of laser two-dimensional code scanning module will be higher. From a distance point of view, the scanning distance of the general scanning module exceeds 30cm, and the density range of the scanned barcode will be wider, and it can read irregular The barcode surface or transparent tape reading, the reading speed is faster than the CCD, the fuzzy barcode reading effect is good, such as the medical device industry is used more.
Small Lockers
Small lockers for sale here we say are single wide lockers, half lockers, box lockers.
These small storage lockers provide secure storage for the jacket, shoes and personal items.
They can be configured in countless ways with any Standard Metal Lockers in our line.
