E28 80cm-200cm Long Distance 2D Scanning Module
With the development technology , especially the popularization of 5G, the management mode of parking lot tends to be more and more smart and humanized. In the past, the traditional charging mode on parking lots and highways had disadvantages such as slow efficiency and easy congestion, which plagued more and more drivers.
The normal barcode reader only can read the bar code and 2D code at the distance less than 60cm.
TOTINFO is committed to solving these problems for traditional parking lots, we developed a long-distance scanning module E28 which can easily fast decode the phone QR code at the distance of 80cm – 200cm even in dark and luminous environments, help the users quickly complete the entry and exit control.
