UV Lamps for Use in Fraud Detection Longwave UV is used in a variety of fraud detection applications. Several examples demonstrate the versatility of UV as a fraud detection tool. For example, counterfeit currency fluoresces under longwave UV, while the paper used in genuine US currency will not fluoresce. The same principle is applied, in reverse to credit cards. Many newer credit cards have an invisible imprint on the front, such as "AMEX" for American Express. If no imprint is detected under longwave UV, the card is a forgery. Another example is verifications of legal documents. Most alterations of legal documents are detectable by longwave UV, because even careful erasure or eradication of ink disturbs paper textures. UV highlights such discrepancies in the paper texture of a document requiring verification. Recommended lamps:
UVL-56
Handheld Lamp, 6-watt line cord lamp, can be placed in the optional J-129 lamp
stand for hands-free use. The ML-49 is a
6-watt portable lamp which operates on two power 6-volt lantern batteries. The
4-watt UVL-23 line cord compact lamp, can be
used with the optional J-124 lamp stand. The mini UVL-4
uses four AA batteries. These four models offer a full range of options for
intensity, power sources and portability at the 365nm longwave UV wavelength
required for fraud detection.
