The NFC chip's antenna is designed as a brittle circuit that breaks when the tag is cut, pulled, or peeled. Think of it like a wax seal on a letter—once broken, it can't be restored.

Instead of a removable tag, the chip can be heat-sealed between fabric layers, woven into the garment, or molded into rubber and plastic components. Removal means destroying the item itself.

At manufacturing, high-resolution photos are captured and stored in the NFT metadata—front, back, stitching patterns, tag placement. Buyers compare what's in their hands to what's on-chain.

Each item has measurable unique properties encoded on-chain: thread count at specific coordinates, weight within tight tolerance, UV-reactive security threads, microscopic print variations.

The blockchain records every ownership change with location data. Red flags trigger automatically: impossible geography, unauthorized transfers, suspicious verification patterns.

The original owner must digitally sign the transfer via the TOLDYA app. Without this cryptographic release, the chip still scans—but status shows transfer was never authorized.

Most chips are destroyed during extraction (~80% failure rate). Acquiring one working tag costs $100-$500+ in authentic merchandise. Selling the resulting counterfeit? Maybe $50-$80. The math doesn't work.

For items verified through the official app at point of sale: authenticity guarantee backed by TOLDYA, dispute resolution process, and refund protection for buyers who were defrauded despite verification.
