Iron Maiden have announced that their forthcoming tour is going to be "paperless":
Iron Maiden have announced their new UK tour will be their first in the country to use paperless tickets. Bruce Dickinson’s band are aiming to cut down the amount of tickets listed for “ludicrously inflated” prices on resale websites. Fans will not receive printed tickets for the group’s May arena tour, but will have to present photo ID and a credit card when they arrive at the show. “We do not want our fans being ripped off either by counterfeit tickets or through costly mark-ups on so-called secondary ticketing websites,” manager Rod Smallwood said in a statement.It's the first UK paperless tour - although they did one in the US.
Not clear what happens if your change credit cards in the nine months between buying tickets and the gig, though. Or what happens if you plans change before the gig.
