Erasable Ink Scam
Someone goes door-to-door, soliciting contributions to a charity. He prefers a check—it’s safer for you, after all. But he offers his pen for you to sign your check, and the pen is filled with erasable ink. Later, he changes both the payee and the amount, and cashes the check.
This surely isn’t a new scam, but it’s happening in the UK right now. I’ve already written about attackers using different solvents to wash ink off checks, but this one is even more basic—the attacker gives the victim a bad pen to start with.
I thought checks were printed with ink that also erased, voiding the check. Why does this sort of attack still work?
