Expressway toll windows are placed outdoors and are often exposed to sunlight. If the selected scanning module does not perform well, it will not be able to scan the code. Therefore, this type of outdoor scanning module must first be able to operate in the sun. Normal use under irradiation.

The second is the interface. Since most of the back-end configurations are serial ports, it is best for this scanning module to have multiple interfaces, such as USB/RS232/TTL, which can meet the needs of different scenarios.

The last is the sensitivity of scanning the code. Due to the large traffic flow on the expressway, the scanning module needs to be sensitive to scanning the code, respond quickly, and can quickly scan the code to pass after charging.

To sum up, XT2003D is a QR code scanning module fully suitable for outdoor use. It has the following advantages:

1. Size: 79*68*53mm, using 640*480CMOS, fast scanning speed for global exposure, using 32-bit CPU, fast computing speed and high scanning sensitivity!

2. It can quickly scan all kinds of 1D codes, 2D codes, mobile payment codes, mobile phones, paper and membership cards.

3. High motion tolerance, up to 2 meters per second.

4. The fill light has the function of automatic dimming, the standby time is dark, and the code reading time is bright. And can automatically adjust the brightness of the light according to the distance of the object.

5. Large window design, wider scanning range.

6. Built-in buzzer, synchronous sound when scanning.

7. The installation is simple, only two screws are needed to fix it.

8. Compatible with a variety of systems, IOSAndroidWindows, etc.

9. Rich interfaces: USBRS232RS485TTL.

Tailor-made for all kinds of outdoor machines (such as vending machines, payment machines, garbage sorting machines), turnstiles, and self-service machines!
