Buying Guide

Choose test methods you need

Look for detectors that match common security features—UV light for security threads and fluorescent ink, magnetic sensors for magnetic ink, and pen tests for paper fiber differences

Consider form factor and workflow

Pens and pocket UV lights are portable for on-the-go checks, while benchtop units and dual-test devices suit regular counter use and faster throughput

Check power source and runtime

Confirm whether a detector uses batteries, built-in rechargeable cells, or AC power to ensure it fits your point-of-sale setup and expected daily use

Evaluate visibility and inspection aids

LED UV lighting, built-in magnifiers, and clear inspection windows make it easier to spot threads, watermarks, and microprinting under different lighting conditions

Prioritize trusted brands and user ratings

Select models from established manufacturers with consistent user ratings and transparent feature lists to reduce false positives and missed detections
