These days tickets for big music tours and sports events can sell out in a matter of seconds. And not everyone who buys a ticket is planning on going. Touts, scalpers, resellers (whatever you know them as) are using increasingly high-tech ways to snap up all the tickets before real fans get a chance, then selling them on for dizzying amounts.

It’s not just big stars like Taylor Swift and Beyoncé, it’s also huge sports events like the Cricket World Cup, the Superbowl and the Euros.

We hear from Rachel Lee, a reporter in South Korea, and Roxy Gagdekar, a reporter in India, about the scale of the problem in their countries. Plus we speak to Alessandro Moretti, a criminologist who’s spoken to some prolific touts to study their secrets.
