Why now

The EU Digital Product Passport mandate.

EU DPP mandate

Required for textile, battery, and electronics products entering the EU market from 2026. Tagnetix Trace is built for this compliance use case.

Target customer signal

"We need to comply with EU Digital Product Passport" or "we need product authentication via NFC." Immediate Tagnetix opportunity.
