Buying LCS Tickets.

I would like to know how exactly the Will Call works for LCS Tickets. I do now have a credit card, but my father is going to pay for my ticket, but I'll be driving there. Do I need my fathers ID/Credit Card to confirm it's my ticket? I'm just a bit confused on how this works, never went to LCS, only 2013 World Semifinals. Any info will help. :)
