Counterfeit Bill Detectors

Choose based on the volume of cash you handle, detection technologies needed (UV, magnetic, infrared, watermark, and MG/MT detection), form factor (handheld, countertop, or portable), and integration needs like batch counting or counterfeit alarms

UV detects security threads and inks, magnetic sensors detect magnetic inks and security features, infrared checks paper and print patterns, watermark detection verifies embedded images, and MG/MT sensors analyze magnetic and magnetic thread properties; models combining multiple methods offer broader coverage

Prices vary by features: basic UV/magnetic handhelds and simple countertop units are generally in lower price tiers (often under a few hundred dollars), while multisensor machines and high-speed counters with counterfeit detection fall into higher ranges; the category average price is mid-three figures

Handheld and compact detectors can reliably spot many common counterfeit indicators when used correctly, but full-size countertop or multi-sensor machines typically offer faster processing, more detection methods, and are better for higher volumes

Regular cleaning of sensors and lamps, replacing or servicing UV/LED bulbs as recommended, keeping devices dust-free, and periodic verification with known test notes will maintain accuracy; follow manufacturer instructions for calibration intervals

Many detectors are designed for multiple currencies and detect generic security features, but effectiveness can vary by currency and model; check product specifications for supported currencies or the ability to detect features common across banknotes

Test the device using a variety of genuine notes and counterfeit test samples if available, use verification cards or reference notes provided by manufacturers, and compare results across different detection modes (UV, magnetic, IR) to ensure consistent responses
