The wide application of 2D scanner modules is closely related to QR code decoding technology products, and there are many manufacturers supplying QR code scanner modules on the market, but these manufacturers are mixed, and the functions of the products are also quite different. Therefore, you must be very careful when choosing a QR code scanner module manufacturer, so how to choose?

1. Confirm the qualification of the manufacturer and whether it has independent core technology

At present, some suppliers are not actually manufacturers, they just take goods from other manufacturers and put their own brands on them. There is no effective communication at all when you inquire about technical issues, and there is basically no after-sales guarantee.

So, how to determine whether the manufacturer has the relevant qualifications and independent core technology?

① Understand the company's comprehensive strength, innovation ability and reputation from the industry, and of course, you can also check it on the spot. Many QR code identification module manufacturers do not have their own core technologies, let alone product R&D. Once it involves technical after-sales issues, basically no one understands them, let alone product quality assurance.

② Whether it has obtained the certification of the quality management system, only companies that have passed the relevant quality management system certification can be said to have quality assurance, and such manufacturers can ensure that the QR code scanner module produced has no quality problems.

③ Whether there is a patent certificate or trademark copyright.

2. Do you have any industry experience?

We also need to know whether the 2D code identification module manufacturer has a long industry experience, because this will be related to the technical after-sales problem of the product. If there are experienced QR code scanner manufacturers, they have a more in-depth understanding of the performance parameters of the equipment and its application scenarios, such as reading depth of field, reading efficiency, scanner distance, size, paper code and screen code. Decoding capabilities, etc., make it possible to comprehensively consider the application of various scenarios when recommending products to different customers. If you encounter technical after-sales problems, you can communicate in time, reduce the R&D design and investment costs of embedded integration, and speed up R&D.

3. Is the product line complete?

Generally speaking, the richer the product line, the more innovative R&D capabilities the company has and the more products there are, for example, products ranging from low-end to high-end, from the mass market to the industry market, and each product is tailored to the customer's application scenarios. , there will always be one that meets your needs.

4. Whether the scanner performance is stable and durable

In fact, the performance and quality of many QR code recognition devices on the market are uneven. The price of good scanner performance is too high, and the performance of low price is not good. This is determined by the 2D decoding chip technology it uses. Whether there is a tempered reading window or professional embedded design, whether it can normally read the mobile phone screen code information in the case of reflection, color film, backlight or dark conditions on the mobile phone screen, whether it can be used normally in strong and weak light, high temperature and low temperature environment etc., are the key points to check whether a 2D scanner module is reliable and durable.
