What are the differences between a real check and a fake one? This is the fake check that I received by UPS lately. It is guaranteed FAKE. I called the bank and had it verified as fraud. Now, the big question: What are the clues that give this away as being a fake? Does anyone here have any answers? Let's learn together how to prevent fraud.
