Buying Guide

Detection methods to prioritize

Choose a detector that includes the tests you need—UV, magnetic ink (MG), infrared, or watermark checks—because no single method catches every fake

Consider form factor and placement

Select between pens for spot checks, compact UV lamps for counters, or multi-function desktop units based on where and how often you'll test bills

Look for multi-test capability

Devices combining UV, MG sensors, and watermark/strip checks reduce false negatives and are more versatile across currencies

Ease of use and speed

Prioritize intuitive operation and fast inspection cycles—especially for retail or front-desk settings where throughput matters

Power and portability

Decide if you need battery-powered or plug-in units; portable, lightweight options suit mobile checks while plug-in units offer consistent power for busy counters
