As a goal, I personally think that the app used first needs enough processes; Secondly, there needs to be enough beacon information in it, preferably every second, so as to find business; Thirdly, the functions should be rich, such as bidding, winning bids, enterprises, performance, personnel qualifications and big data analysis. The more of these functions, the better. Of course, the final price should not be too expensive.
Now there is a consensus in the industry. There is a charge for this thing, but I can't accept a member asking for 1w, which is too exaggerated. If it is used by ordinary salesmen, a few hundred yuan is acceptable.
