Starting with the 2025 series, all Goldback notes include UV-reactive security markings on the reverse side. This authenticator is tuned to the precise 365nm wavelength required to reveal them instantly.
Built for everyday use in the field. The black glass lens, IP68-rated waterproofing, and 1.5m impact resistance mean it survives the environments where Goldbacks actually circulate. At 5.2 inches long and 0.67 oz, it fits in a pocket.
Two output modes:
High (850mW): up to 1.5 hours continuous, 15 to 20 meter beam range
Low (165mW): up to 8 hours continuous, 5 to 10 meter beam range
Runs on one AAA battery (not included). Compatible with all 2025 and later Goldback notes across every state series.
If you're buying, selling, or accepting Goldbacks at the register, this is the verification tool designed for the job.
