YouTube icons Gierige Gasten have once again devised a lucrative way to visit a festival cheaper. This time they have found a "leak" in a ticket system, allowing multiple people to visit the festival by using just one ticket.
In the video below, they claim that visitors who have the same ticket scanned will pass the ticket check within 5 seconds without facing any problems.
The unique barcode or QR code is sent to a server as soon as the ticket is scanned. Processing this takes a few seconds at some ticket providers. However, this processing time depends on the internet speed and server settings. During this processing time it is possible to scan two tickets with the same barcode.
The ticket provider can set whether each ticket is only approved after the processing time. This can take approximately five seconds. This can hinder a rapid flow of visitors, which is why many ticket providers do not apply this method. This means that the scanners accept tickets that have not yet been fully processed in the server, which causes a "leak".
It is and remains a calculated risk for visitors to apply this method. At large events, precise timing of scanning is practically impossible. This means there is always a risk of getting denied to the event.
It is possible to rent local terminals at our hardware partner (R&S). These terminals can be used to speed up the process time of the scanners. This makes this method unusable since the precisely timing becomes impossible.
In addition, the scanners of Eventtool are connected to each other, allowing both online and offline scanning. So the tickets are registered, even if the internet connection is lost. And last but not least, the ticket is linked to the scanner, allowing the employee to see whether the same ticket has recently been scanned by another colleague.
