There are some places lately with online ticket sales - I'm thinking particularly of http://www.dnalounge.com/backstage/log/2013/04/26.html http://www.dnalounge.com/backstage/log/2013/04/26.html - who have begun to demand not ID, but the credit card with which the ticket was purchased. It's an interesting anti-scalping measure.
