Metal Detectors Can Detect, Count Your Cash

Think those TSA agents waving a metal-detecting wand at your pockets only know how many coins you're carrying? Think again.

Metal detectors can tell how much cash is on you, too, according to a new study by researchers at the University of Washington's Applied Physics Laboratory in Seattle, the Daily Mail reported.

The handheld metal detectors get signals from the magnetic ink dollar bills are printed with, and the strength of the magnetic signals increases when bills are stacked together.

In other words, don't try smuggling big stacks of cash through airport security.
