Check Washing
 

Always wondered how they did it! If you pay your bills by check, then you need to watch this film clip. This is VERY interesting -- and you will want to go get a Uni-Ball 207 pen!

Office Max, Wal-Mart, and Office Depot have them. They are marked "Helps Prevent Check Fraud" on the packaging.

Or you could just have a checking account with a bank that has checks that will show markings if it's been 'washed'.
