Why do they wipe you at airport security?

While it's generally luggage that is subject to swabbing, travelers clothes and hands may also be swabbed. Swabbing is used as a secondary form of detecting explosives alongside full-body scanners. While the process can be a little intimidating, a positive swab test is no need to panic.

The “why you” is pretty simple – it's usually at random. Unless you're on the super-secret list that increases your chances of getting SSSS on your boarding pass, the TSA's machines are said to pick people at random for swabbing. As for the why, they're usually checking for traces of explosives.

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.

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. I find it interesting that they were checking hands—perhaps that's more accurate than some of the other sampling sites they've used in the past.

TSA's purpose is ensure that dangerous articles and substances do not get past the security checkpoint and onto an airplane.
