It says in the FAQ "Your government issued photo ID MUST match the name on the credit card", and on the presale entry page it said "The ticket purchaser must be present at the time of entry, and must attend the event". This seems to be a strict rule so I really doubt they would let you in with your wife's card - I definitely read that you wouldn't be allowed access with a parent's card, even though the surname would be the same. Good luck though!
