Fast QR Code Scanner Module for Access Control Mobile Payment

Nowadays, QR code scanner is widely used in access control system for mobile payment.

The traditional payment method in metro station is IC card, not barcode payment. But with the development of mobile payment app such as Alipay and we chat, QR code payment becomes popular in many countries, including China, India, Mexico, Brazil, etc.

For access control project, Wiegand protocol is almost the most frequently used communication protocol. However, most QR code reader has USB or RS232 interface, instead of Wiegand. As a leading barcode scanner supplier, Rakinda can solve this problem for you. We can provide a complete set including scanner and Wiegand converter. Below picture shows the converter.

How to transfer data? 

The converter transfer data based on standard RS232 protocol, Baud Rate 9600 N 8 1

When transferring ASCII output data to Wiegand output, most customers transfer data from their own software, for example, sending 1234567890 from COM to our RS232 input interface, so our Wiegand output interface shall output data as Wiegand 34bit, connect to access controller, you can see access control software show a card number: 1234567890. The same application, if a barcode scanner connects to access controller via our converter, so when the barcode scanner output 11223344, so the access control software shall show 11223344.
