With the popularization and development of barcode technology, we have unknowingly come to the era of code scanning. In such an era, subway gates scan code to check tickets, smart access control scan code to open the door, and self-service machine scan code to pay... Knowing that these were very rare in the past, and now we are accustomed to their existence, but there are embedded QR code scanning modules in them. I wonder if everyone knows it. It doesn't matter if you don't know, the editor will introduce the barcode scanner next.

What is a barcode scanner?

A barcode scanner is a device specially used to collect and identify 2D codes, and it also has the function of data transmission. There are many aliases for QR code scanning modules, such as QR code scanning modules, QR code readers, QR code recognition engines, and barcode scanning heads.

The volume of the QR code scanning module is much smaller than that of a handheld scanner or scanning platform. It has the function of system integration. In simple terms, it can be installed inside the machine for use, such as self-service machines, subway gates, QR code access control, high-speed toll stations, assembly lines, etc., all have embedded QR code scanning modules.

How to choose barcode scanner_QR code scanning module?

There are many types of QR code scanning modules, and their choices are also confusing to many people. They often do not know where to choose. Based on years of experience, Shenzhen Xingtong IOT said that the following five aspects can be considered first:

1. Performance: The performance of the QR code scanning module is related to the efficiency of the module. If the performance is good, the scanning efficiency will be fast; if the performance is poor, the scanning efficiency will be slow.

2. Function: The QR code scanning module can not only realize the scanning effect, but also realize the functions of payment and electronic ticket verification. According to your own needs, choose the appropriate QR code scanning module.

3. Size: The QR code scanning module has different sizes. When purchasing, choose the QR code scanning module based on the space prepared by the application.

4. Model: There are many QR code scanning modules, and the models are also varied. When choosing, you need to pay attention to whether the model can achieve the effect requirements.

5. Price: Different models of QR code scanning modules have different prices. Take the hard decoding module and the soft decoding module as an example. The former has a higher price, but its performance is better and more stable. Although the latter is low in price, it is prone to errors.
