InternetEvolution points out a legal quandary: many concerts prohibit cameras. Given that iPhones—along with other smartphones—include cameras, could they be banished?
Maybe not, if the phone is kept discreetly in a pocket. But if customers are going to be scanning it with security to gain entrance, it would be difficult for the guards to look away.
This quandary raises even more disturbing issues. What if the customer displays a ticket that is only good for yesterday's concert? The guard can't "take" the ticket and deny access. Would the phone have to be handled by security?
Would consumers be required to hand over their phones for inspection, the way they'd have to hand over a credit card? Or have the phone potentially be taken away?
What if the customer goes to buy some t-shirts and the card number associated with the phone gets rejected as stolen. Standard procedure asks that such a card be held—or sometimes cut up. What are the implications of having data on the phone? Do cashiers have the right to hold and examine a phone as they would a credit or debit card?
