In the era of mobile payment, the application of bar code scanning module is more and more extensive, and various intelligent self-service terminal applications have appeared in our field of vision, and play an "electronic eye" in the process of realizing the mobile consumption mode of scanning code payment. The role is the barcode scanning module. How much do you know about the module? Let's make a good introduction for our YHD-M300 (2D) with friends!

The YHD-M300 (2D) scanning engine uses the world's leading chip-based intelligent image recognition technology to create a new era of image-based 2D barcode reading engine. Germany's two-dimensional decoding chip combines advanced image recognition algorithms with advanced chip design and manufacturing technology, which greatly simplifies the design difficulty of 2D barcode reading products, and establishes high-performance, high-reliability and low-power of 2D image products. A good benchmark for consumption. The image collector is integrated with the decoder board, which is small, lightweight and easy to integrate. Suitable for use in products embedded in various industries, such as PDA products, POS products, tablet devices, portable devices, etc.

To sum up, the product features of the YHD-M300 (2D) are mainly:

First, the core technology

Using the fifth-generation core decoding technology independently developed, we can quickly read barcodes of various qualities.

Second, high reading performance

Integrated high-performance decoder with fast decoding and high-precision reading capabilities, easy to read mainstream 1D barcodes on the market.

Third, the interface is rich

Four interfaces of USB/RS232/TTL/MICRO USB are provided to meet more interface requirements.

Fourth, high integration

The image collector is integrated with the decoder board, which is small, lightweight and easy to integrate.

Five, green low power consumption

The use of independent core technology greatly reduces operating power consumption and extends equipment life.

So how does the 2D scanning module work?

First, the standard bar code scanning module that is generally produced is equivalent to a bar code scanner without a casing. To use the barcode scanning module, you first need to link the scanning module to the power supply and the host (sometimes the power is directly provided by the host). Before the host connects to the scanning module, it is best to keep the host shut down to avoid damage to the machine and interface; After that, set the communication mode between the reader and the host, and scan it by scanning the barcode on the user manual. After the setting is completed, it can be scanned and uploaded to the computer. Only when connected and set up, the 2D scanning module can play its powerful functions.

In addition, some users connect and set up, or can't read barcodes. What is the reason?

There are several main reasons:

1. It may be that the function of reading such a barcode is not turned on in the setting;

2. It may be that the barcode does not conform to the specification. For example, the necessary blank area is missing, the contrast between the strip and the space is too low, and the width ratio of the strip and the space is not suitable.

3. The device is in direct sunlight and the sensitized device enters the saturation zone.

4. The surface of the barcode is covered with a transparent material, and the reflection is too high. Although the eye can see the barcode, the collector reads

The conditions are strict and cannot be read.

5. Hardware failure, contact your dealer for repair.
