General query software provided by touch integrated machine manufacturers: only most of them need extra charge. The function is also very powerful, which can meet the needs of most customers. However, the suggestion is: if you buy with the touch integrated machine manufacturer, you must first confirm the functions required by the software.
If the functional requirements are relatively high and the quantity is relatively large, you can contact a software company to develop a set, which will cost more, but the functions can be customized.
