I found an old ticket puncher. Some ones are in using at this times too. This machine are on the public transport, on buses, trams... When somebody buy a ticket, he take on the bus, and he must punch the ticket with it. It make 3 holes to the ticket's 9 number. It has 84 combination. The controllers control the hole combinations, if they come. If somebody don't have ticket, or the ticket don't have good combination holes, the controller chasten.
