What problems should I pay attention to when placing vending machines?

You should pay attention to all these factors you mentioned.

At present, snacks and drinks machines and adult vending machines are common in the market.

Retail category: closed schools, factories or shopping malls with large crowds.

Adult vending machine:

Try to go at night when choosing the site, because most of the products promoted by the partners are adult products, and the peak purchase time of such products is 6- 12 at night.

Try to choose a place near a lot with a large flow of people, but not in the bustling city center, but in a quiet place in the city center.

Close to a relatively densely populated residential area or through a large number.

Railway stations, bus stations, bus lines, hotels, hotels, entertainment areas, factories, near university towns, etc.

With the help of cluster effect, it is chosen near the traditional adult goods store that has already opened.

I hope the above can help you.
