Why do they wipe your hands at airport security?

TSA officers swab your hands with a cotton cloth to collect explosives residue for testing in an Ion-Mobility Spectrometer (IMS), the machine they put the cloth in that determines if you go to your gate or to a private security screening for a pat down and metal detector.

Does airport swab test for drugs? They are not testing passengers' DNA, testing for viruses or illnesses, and the testing equipment does not test for narcotics. But be warned — an additional search that turns up drugs can get you into trouble, and refusing the swab test can get you referred for additional screening.

Those are things like explosives or knives made out of materials other than metal, like ceramics, says Malvini Redden.

Can you see a tampon during an airport body scan? This is a frequently asked question on Google, and if it's something you're worried about, you can breathe a sigh of relief. Airport body scanners can't see inside the body and therefore can't detect a tampon on a TSA female body scan image.

Various nitrates are often used in the making of explosives (e.g., trinitrotoluene, a.k.a. TNT) and they're checking to see if you've been handling any recently.

The TSA largely looks for physical evidence that a passenger could be a threat, so they'll generally have no reason to search through the data on your phone. After all, they're the Transportation Security Agency, not a detective agency. Even if they did have reason to want to access your phone, they'd need a warrant.
