Magnetic Sensors: TMR Sensors vs. Segmented Magnetic Heads
Counterfeit detection in banknote handling equipment has become increasingly sophisticated—but the core challenge remains the same: authentic banknotes carry subtle, repeatable “signatures” that many counterfeits fail to reproduce consistently. Among the most reliable of these signatures are magnetic features—because they’re hard to imitate with standard printing and materials, and because magnetic sensing can work even […]
