The PSA/DNA Advantage

The PSA/DNA In-the-Presence authentication process virtually eliminates the problem of counterfeits and forgeries and allows items to be verified each time they change hands.

  1. PSA/DNA representatives witness the item being signed, guaranteeing the authenticity for life.
  2. The item is tagged with permanent, invisible, synthetic DNA-laced ink, verifiable using a proprietary infrared laser.
  3. A Certificate of Authenticity, which contains an embedded logo hologram, is issued and a matching, serialized tamper-evident label is affixed to the item.
  4. Pertinent information including the signer, the type of item, signing location, date, and any notes are logged into the online database for verification.
DNA Ink

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!
