First of all, let's take a look at the reason why the scanner of the cash register can't read the data. The reason is found. It is much easier to get the right medicine.
The reasons for this are as follows:
1. Direct sunlight, the photosensitive device enters the saturation zone;
2. The bar code does not conform to the specification. For example, the necessary blank area is missing, the contrast between the bar and the space is too low, and the width and width of the bar and the space are not suitable;
3, the surface of the barcode is covered with transparent material, the degree of reflection is too high, although the eye can see the barcode, but the collector has strict reading conditions and cannot read;

3. For the surface of the bar code covered with transparent material, the reflection degree is too high, refer to the first solution;
4. If you do not open this function, open it in time to avoid delaying normal work.
