Tagd

Tagd is the identity, provenance, and verification product: bind physical products to verifiable digital identity, then generate, verify, and govern them across regulated and brand-protection workflows.

Signal Tags is the underlying technology and schema concept that powers Tagd — scannable identifiers (QR, NFC, barcode) bound to verifiable identity and provenance. Signal Tags is a capability of Tagd, not a separate product (TAGD-DOC-01/02); @betterdata/signal-tags-schema is a technology reference.
