I just happen to go to the San Francisco air port too see off my friends and found there is a separate lane where if you are member of “Clear Card” you don’t have to stand in the big line. There is separate lane, they check your ID do a Scan and you are In.

I quickly grabbed a voucher and here is some more information

- What is the first thing that comes to my mind is ofcourse Money
They say firt year it is $100.00 and TSA fee of $28.00

- How long will it take to get a card
2 to 3 weeks.

- Interesting thing, you can give a Clear card as a gift.
Yes, probably a good one to give some one as a gift.

I would recommend you go to their website and find out more information here
