I understand that we can start to get U of T card starting from June 17, but don’t we have to bring in anything, ie. a letter from U of T to prove that we have officially accepted U of T and U of T has officially accepted us?

I am an American and i have found out that T-cards are available on June 17th. Do I have to be in Toronto to recieve the card or can I register or do whatever it is I need to do in order to get my T-Card online and have it mailed to me? Can i pick it up over the summer? Sigh…
thanks,
a slightly confused little american

where and when do i get my photo id? i went to orientation and wasn’t paying attention when every one was speaking about stuff that mattered to my livelihood.
