I am. I have been in SJC by last year and it was 1 backscatter machines at terminals A. I was there during same-day trip. My friend & I went through at checkpoints with an escorted badge. I saw huge new security checkpoints while they renovated it the entire Terminals A. Other temrinals B will have go through at security and its exactly go through the same concourse where you go to another terminals A without rescreening at security. You have to stays in security.
