What is Authentica?
Issue a branded, numbered Certificate of Authenticity with a QR code anyone can verify. No NFT, no crypto.
Authentica issues a Certificate of Authenticity for every item sold, automatically. Each certificate carries its own serial number, a private QR code, and a cryptographic signature and fingerprint, all hosted on a verification page on your own store. Buyers, and any future owner, confirm an item is genuine with one scan. No wallets, no crypto, no blockchain, and never a fee per certificate.
How Authentica works
Install → pick a category and design the certificate in the drag-and-drop editor → every paid order issues a signed, serial-numbered certificate with its own QR verification page → buyers verify instantly, transfer ownership on resale, or report a problem → a refund revokes the certificate automatically.
