Is using a cash register at several locations allowed in Hungary and what is required in such cases?

One of the situations for a retailer that could occur is the need for the usage of a cash register at several locations, for example, with the same cash register operating in one location in the morning and another in the afternoon (variable location), or in one location one day and at another the next. Therefore, the question arises: would these cases be allowed and in what way, as well as should there be any notifications to the tax authorities if permitted?
