To prevent fraud, no action is required on your end besides checking in your guests with Ticket Division Scanner. Each ticket is identified by a unique encrypted barcode that Ticket Division Scanner reads and mark as used. Tickets cannot be used twice. And because Ticket Division Scanner synchronizes data and all connected devices in real time, if a ticket is used at two different points of entry using two different devices to check in attendees, the device reading the ticket for the second time will show a warning screen, informing the door person that the ticket has been used already.
