Why it’s getting harder to spot counterfeit cash

When a woman stepped into a Great Clips salon last year in Tracy, California, with her two children in tow, manager Julie Rudnick didn’t suspect a thing.

And when Rudnick used a counterfeit detector pen on the $100 bill the woman paid with, the ink stayed clear — the mark of a genuine bill.

It wasn’t until she took the money to the bank a couple of days later that she was told the bill was a fake.

Harder to detect, easier to make: This is the challenge posed by advancing technology in counterfeit money.
