The iDetector is a quick and easy way to detect counterfeit currency, travelers checks, credit cards and IDs such as drivers licenses and passports. It offers a "triple check" for US currency:
It can check many foreign currencies such as the Canadian dollar, Euro, Peso, and the Yen. Additionally, it can authenticate resident alien and green cards, money orders, passports, credit cards and even drivers' licenses from many states. It is cordless and lightweight so it can be set up anywhere and is easy to use so training time is limited. The iDetector uses 3 AAA batteries (included) and comes with a complete set of instructions.
