This scanning module reads barcodes or 2D codes with a scan speed of 15m/min. With small size and high-efficiency recognition, it is easy to be integrated into various industrial equipment and applications.

The module is equipped with a 0.3megapixel camera and auxiliary lights, white light illumination, and red light focusing, which makes it able to effectively identify codes in low-light environments.

The module automatically senses and scans, identifies the surrounding environment. Once being auto-triggered, it quickly recognizes and reads code. The scanner also has TTL-232 and USB two communication interfaces for more actual scenarios.

It uses CMOS image recognition and core decoding algorithms to quickly recognize various barcodes and QR codes. Plug and play, no need to install drivers. The module is compatible with many mainstream operating systems such as Windows, Linux, Android, and Mac.

In addition to recognizing ordinary QR codes and barcodes, it can also recognize laser codes and other high-density code systems, which is applicable to various embedded environments such as mobile payment, access control, and self-service shopping.
