What do MG, UV and IR stand for?
There are 3 main counterfeit detection techniques used in the majority of discriminators and detectors:
- MG – Magnetic Feature Detection – US currency uses specific magnetic ink at exact locations to provide a unique magnetic signature on each denomination note. By scanning each bill for the presence and location of these features, the Signature is capable of detection the minute magnetic signals present on these bills and will flag any notes that do not have these features present, in the correct locations. Certain counterfeit notes do not have the same features and will be rejected by the Signature as ‘SUSPECT’
- UV – Ultraviolet Feature Detection – Certain features are hidden to the naked eye on all US currency. In order to detect these features, the Signature has special ultraviolet emitters and sensors capable of detecting the exact ultraviolet anti-counterfeit features built into each denomination note. These are referenced against known-genuine currency and used to flag any notes that do not display the correct UV features on the suspect notes.
- IR – Infrared Feature Detection – Similar to UV, US currency contains hidden infrared features that can only be detected by infrared illumination and detection. The Signature scans each bill for the presence and accuracy of these features and fails any bills not meeting these criteria as ‘SUSPECT’.
