Radio frequency identification (RFID) technology has been used at a number of festivals around the world, for paperless tickets through to cashless payments on-site. Now the Lollapalooza festival in the US is launching a major initiative using the tech called Lolla Cashless, which will make its debut at its Chicago event in August. People buying tickets will be sent wristbands and given the option of registering their credit cards online. They’ll then be able to buy food and drink by tapping their wrists on payment pads and tapping out a PIN. “We feel like not only will that be big for us, but it will end up spreading across some of the other major festivals,” Patrick Dentler from Lollapalooza producer C3 Presents.
