Three questions before “genuine.”
For jerseys, caps, hang tags, seals and ID cards. The mark is built in layers, and the reader fires a changing sequence of light at it, so a copy has to get every answer right, in the right order.
- Three layers. An overt layer anyone can see under UV, a covert layer that answers only to infrared, and a forensic layer for the lab.
- Challenge and response. One ultraviolet and two infrared colors of light. The reader can change the order every time.
- Brand color, measured. The glow must match the team or brand color within a set tolerance (ΔE in CIELAB).
- Color, spectrum and time. Authenticity rests on at least two of the three, including how long the glow lasts.
- Pass, retest or fail. A match score with two thresholds asks for a second scan when the result is borderline, and every check can be logged.
