A plurality of embedded devices with scanning functions usually have insufficient compatibility with various scanning heads such as one-dimensional scanning heads and two-dimensional scanning heads, so that the application range of the product is single, if the application scene changes, the performance of the product may not meet the requirements, and different scanning heads have to be re-developed and adapted to meet the requirements of different users.

Thus, in at least one embodiment of the present invention, the barcode information includes a one-dimensional barcode and a two-dimensional barcode.

The reading distance of the UHF module in the existing hand-held terminal equipment is divided into short distance, medium distance and long distance, the UHF module is applied to different scenes (medical industry, rail transit industry, logistics industry and the like), the common embedded equipment cannot be compatible with the modules with the three identification distances at the same time, the universality is not strong enough, and the application range of products is limited.
