QR Codes on Sports Memorabilia: Authentication Certificates and Chain of Custody

1. The Forgery Problem

Signed jerseys, balls, and photographs are frequently forged. A QR code on the certificate of authenticity links to a registry showing provenance, the authenticating company, and the chain of ownership.

2. Holographic Certificate plus QR

Many authentication companies pair a holographic sticker with a QR. The hologram provides visual tamper evidence; the QR links to the digital record. Both must be present for full confidence.

3. Blockchain Registry

Some platforms record each ownership transfer on a blockchain, creating an immutable history. The QR links to the public transaction record. The value is only as strong as the initial authentication.

4. Buyer Guidance

Before purchasing, scan the QR to confirm the certificate is genuine, the player details match, and the ownership history is consistent. Any gap or mismatch is a red flag.
