The TSA Notification Card allows travelers with disabilities to discreetly inform airport security personnel about any medical conditions, disabilities, medical devices on their person or medications that might impact the screening process.

A doctor's note for airport security is a formal, signed letter from a medical professional that explains why a passenger is carrying specific medical equipment or medications that might otherwise be restricted. This is particularly important for carrying liquid medications over 3.4 ounces, syringes or needles (for insulin or other injectables), and specialized devices like CPAP machines, oxygen concentrators, or internal pacemakers. While the TSA and international security agencies (like the UK's CAA) generally allow these items, a doctor's note serves as vital "proof of necessity" to prevent confiscation or prolonged questioning. The note should ideally be on official letterhead and include the passenger's name, a brief description of the condition, and a list of the required medical items. In 2026, it is also recommended for those with internal metal implants (like hip replacements) to carry a medical card to explain why they might trigger a metal detector, ensuring they are treated with dignity and potentially offered an alternative screening method like a pat-down or a body scanner.
