The PSA/DNA Advantage
The PSA/DNA authentication/identification process virtually eliminates the problem of counterfeits and forgeries and allows items to be verified each time they change hands.
- Item is signed in the presence of a PSA/DNA representative.
- Permanent, invisible, synthetic DNA-laced ink, verifiable using a proprietary infrared laser, is used to identify the item.
- Certificate of Authenticity is issued and the item may be tagged with a matching, serialized tamper-evident label.
Together, the non-transferable, tamper-evident PSA/DNA label, matching Certificate of Authenticity, and synthetic DNA used to permanently identify items provide ironclad security.
The chances of replicating the synthetic DNA used by PSA/DNA are 1 in 33 Trillion!
