The TSA PreCheck program just opened up to the general public. Applicants must provide general personal information, such as height, weight, hair color, address, date of birth and a government-issued ID. If approved, then travelers will receive a Known Traveler Number (KTN) If you think PreCheck will allow you to skip body and bag scans, then it is still required. PreCheck “enables us to focus on the travelers we know the least about, adding efficiency and effectiveness””]
