With the popularity of mobile payments, nowadays many young people travel only with mobile phone.They not only don’t need to carry cash,but also don’t need to carry with NFC card when they go into subway station where has turnstile.Because when the 2d barcode scanner embedded into turnstile with wiegand board for access control,our life are getting simpler.

The fixed mount barcode reader can be embedded into turnstile to read printed or screen barcodes.When we want to go through the gates,only open our mobile phone’s APP application software to generate electronic bar code as tickets.

At first,the turnstiles’ barcode reader reads the electronic bar code from mobile phone.And then the turnstile upload data to the background access management system to identify whether the tickets of electronic bar code are valid.Finally,if the electronic tickets is effective,the wiegand board will respond and open the turnstiles’ door for allowing guests to enter.

What is Wiegand protocol?
The Wiegand protocol is a communication protocol developed by Motorola that applies to card readers for access control.The Wiegand protocol does not define the baud rate of the communication and does not define the data length.Wiegand format is the main definition of data transmission: Data 0 and Data 1 represent the transmission of 0 and 1.Now the most common Wiegand format is 26bit, the others including 34bit, 36bit, 44bit and so on.

How does the barcode scanner module connect with the Wiegand Board?
General turnstile needs to support the Wiegand protocol for access control.But the common interface of barcode scanner is RS232 or USB,so it must be converted to Wiegand output from USB or RS232.Next,I’ll show you how the scanner of the RS232 interface is converted to the Wiegand output by using Wiegand board.

The Wiegand board has seven different colored lines.The green line and white line represent Data 0 and Data 1 of Wiegand data output.The black line and red line connect with 12V power adapter,the black,yellow and brown these three lines of Wiegand board separately connect with black,orange and brown lines of barcode scanner.The black line and red line of 5V power adapter separately connect with black line and red line of barcode scanner.

Barcode Scanner Products Recommended：
RD4600 2d barcode scanner has a interface is USB or RS-232.It read printed or screen barcodes very well. At the same time, with small streamlined design, in addition to the perfect embedding in the various types of self-service machines,it also can be directly placed in the external to use,which is very nice.
