**InvisiInk – Smartphone-Resistant Ink for Secure Writing**


InvisiInk is a novel dual-reactive ink technology designed to resist smartphone camera capture while remaining fully visible to the human eye. It offers a new class of privacy-enhancing writing and printing applications ideal for secure signatures, confidential notes, examination documents, and financial records.

This innovative ink temporarily shifts its optical properties when exposed to light in the 380–450nm range and mild heat (35–40°C), disrupting digital sensors without requiring any special filters or readers. It can be applied using standard pens or printing methods and is particularly valuable for organizations handling sensitive printed information.

The technology is protected as a trade secret and has been timestamped for verification. Technical documentation and composition details are available under a signed NDA.

**We are seeking:**
- Licensing partners
- Joint development with R&D institutions or pen manufacturers
- Potential acquisition offers
