A counterfeit detector pen is a felt tip pen containing an iodine solution that can be used to help identify computer generated counterfeit bills. According to United States Secret Service date, funny money generated by criminals using computers and ordinary printers accounted for only one-half of 1 percent of the counterfeit bills confiscated in 1955. By the year 2000, that figure has risen to 45 percent and is still going up. Counterfeit detector pens, although not fool proof, are an effective way to identify computer generated counterfeit bills because the iodine solution in a detector pen reacts with starch, which is commonly found in the wood based copy paper used by most printers.
