This book can be used for good or evil. The title suggests it is tempting people to cheat on their expense reports, however the best way to catch a cheater is to know how they cheat. The choice is yours, however it is really meant as a tool for people who approve expense reports to catch bogus claims. I knew no one would buy a book on how to catch cheaters, thus the title of the book. Numerous magazine, newspaper, and television stories have spot-lighted this book. Key software makers, travel websites, and payroll processing companies have used my book to improve their detection systems.
