If a passenger has metal implants, such as artificial knees or hips, he or she should inform a Transportation Security Officer (TSO) before screening begins. Passengers can use TSA’s Notification Card to communicate discreetly with security officers. However, showing this card or other medical documentation will not exempt a passenger from additional screening.

Many passengers with metal implants that regularly alarm a metal detector prefer to be screened by imaging technology in order to reduce the likelihood of a patdown being necessary. A passenger can request to be screened by imaging technology if it is in use and available at the checkpoint.

If a passenger cannot or chooses not to be screened by imaging technology or the passenger alarms a walk-through metal detector, the passenger will be screened using a thorough patdown procedure.
