I phoned AXS who deal with the O2 shows and they said because my wife had the same surname as me (?!) i could take her card and use my ID. This seems perfectly logical. You have a while to sort it out, i'm sure there will be many in your boat. Ultimately its just to deter touts and shouldn't piss of the ticket buyer. I think its a ridiculous rule personally, especially since Ticketmaster have their own tout site Get Me In! Its ridiculous. Just keep asking, i'm sure it will work out.
