Nowadays, there are more and more payment methods for smart vending machines. Among them, QR code payment on mobile phones has been popular for a long time, and it has continued until now. At this stage, most vending machines in most sales markets still support QR code payment. This integrated technology must install a 2D code scanning module, and use the embedded CMOS photosensitive device and special lens module to realize barcode scanning technology for various self-service systems, solve the problems of mobile phone Alipay, WeChat payment barcode scanning, etc., and bring a new scanning experience .

QR code scanning modules have been widely used in vending machines, but currently there are very few terminals that use the scanning module to swipe Alipay and WeChat payments on mobile phones. The payment can only be completed by "testing back and forth" in the sensing area of the module. In this situation, Shenzhen RAKINDA has launched various OEM embedded QR code scanning module application solutions such as an upgraded version of the embedded mobile phone QR code reader (RD4500 series) to help vending machine manufacturers innovate Change, while providing customers with a comfortable and convenient scanning experience. Now we have found a self-service terminal equipped with Shenzhen Envision Technology RD4500R series QR code scanning module, and tested the performance of the scanning module through a number of tests.

Let's take a look at how this QR code scanning module works. The scanning module is embedded in the position of the two-dimensional code reading window. When the mobile phone two-dimensional code (such as QR code, payment code, etc.) is close to the scanning window, the device starts up instantly and performs fast reading, that is, through the international advanced smart chip algorithm. Complete the quick decoding, and form the corresponding electronic data and send it to the terminal to realize the reading of the 2D code information.

In the test of the RD4500R in complex application environments such as insufficient light and color film on the screen, every time the QR code of the mobile phone is aligned with the scanning window, the code scanning and reading are very smooth, and the specific process will not be demonstrated. After actual testing, the decoding speed of the RD4500R series 2D code scanning module is extremely fast, and supports the reading of mainstream 1D and 2D paper codes and mobile phone screen codes on the market. Realize the intelligent supplementary light effect under strong light and weak light conditions, and ensure easy reading of barcodes.

Through the above tests, it is not difficult to find that the RD4500R series QR code scanning module adopts a unique 2D reading engine, which can scan quickly and accurately. It is optimized for mobile phone screen code scanning, and is more suitable for mobile phone Alipay and WeChat payment barcode scanning.
