Set scanned tickets as used

A setting that puts the ticket(s) to 'used' after the barcode is scanned in.

Let’s say that someone bought 3 tickets. They come to the checkin and are only 2. We scan in the ticket with barcode scanner and put in ‘2 used', when number 3 comes and scan his ticket, we mark number 3 as well as used.
Or when the buy 3 tickets, they get 3 different barcodes (tickets).

Today they can pay for 1 ticket and 20 people can use it without any control.
