With the development of mobile payment and intelligent technology, two-dimensional code reading technology is more and more widely used in self-service equipment. Whether it is a vending machine, a self-service ordering machine or a self-service ticket collection machine, etc., barcode reading devices such as QR code modules and embedded barcode readers are installed to facilitate users to scan codes for payment, supporting a variety of automatic identification solutions , not only can scan the QR code, but also can read the mobile phone Alipay, WeChat payment barcode, etc.
Why are QR code scanning modules favored by more and more OEMs and end users?
The code scanning module is an automatic identification technology based on the imaging principle of CMOS image sensor technology to accurately scan and read paper, film, and screen. It has the advantages of high recognition accuracy, fast decoding speed, and low bit error rate.
The main purpose of placing self-service equipment on various occasions is to provide more convenient services. By using barcode reading devices such as QR code modules and embedded barcode readers to read payment codes on highly reflective surfaces such as mobile phone screens, It allows users to complete payment on self-service devices, eliminating the need to use traditional payment methods such as banknote recognition and change, which not only improves the convenience of payment, but also improves the flexibility of applications.
More importantly, compared with other payment methods, the access cost of QR code reading technology is lower. Installing the QR code module can reduce the operating cost of the equipment and save the cost of hardware equipment. At the same time, since the code scanning module technology uses an encryption algorithm, the security of the payment process is ensured and the risk of the user’s personal information being leaked is avoided. Therefore, in terms of security, the use of QR code modules has strong application advantages.
