Paper-Money Testing Devices TRIZ Cases
- Anti-Counterfeiting Object With Composite X-Ray Signatures
An optical marking pairs with a multiphase authentication volume to create a difficult-to-replicate X-ray diffraction signature.
- Paper Sheet Handling Drive Unit Sensors for Predictive Replacement
Sensors and property memory track drive-unit degradation in paper handlers, helping predict failures and reduce unproductive downtime.
- Valuable Document Foil Authentication With Dual-Wavelength Infrared Signature
Dual infrared wavelengths and a spectral foil layer help detect composed document forgeries.
- Value Document Luminescence Testing with Rank-Based Measurements
Rank-based luminescence checks reduce distortion from printing and soiling.
