It can. U2 did something similar in Vancouver - you needed to show the credit card the ticket was bought with in order to get in. It created huge lineups (a couple hours long) and a lot of fans missed the opening band (Mumford & Sons) [1]. Eventually they just started letting everyone in without checking credit cards, so they could get in before U2 came on. Maybe it works for the 20,000-seat arenas NIN plays in, but it sure didn't work for a 54,000-seat stadium.
