Questions and Answers
COA Scan Frequently Asked Questions
Direct answers about scanning, matching, verification status, copied QR codes, and public access.
What is COA Scan?
COA Scan is the public verification experience for COA Chain. It retrieves the COA.1 registry record behind a QR code or verification link and displays the permitted identity, certificate, product or batch, status, and record-integrity information.
What happens when someone scans a COA Scan code?
The scan opens the related COA.1 record, checks whether the registry record exists, matches the available organization and product or batch details, and shows the current verification status.
What does a verified COA Scan result mean?
A verified result means that the displayed COA.1 record was found and the listed relationships and status checks were confirmed against the COA Chain registry. It does not independently prove scientific accuracy, product safety, or regulatory compliance.
Can someone copy a COA Scan QR code?
A QR image can be copied, but the live COA Scan result can show the registered organization, product or batch, status, and other permitted details. A copied code that is used for the wrong seller, product, or batch can therefore expose a mismatch.
What should I do if a record is not found, inactive, or does not match?
Do not rely on the displayed certificate alone. Review the result details, confirm the product or batch information, and contact the listed organization or COA Chain for clarification.
Do customers need an account or cryptocurrency to verify a record?
No. Public COA Scan verification is designed to be accessible through a normal web browser without a blockchain wallet or cryptocurrency.
Give customers a live verification result—not just a QR code.
Register your organization, create COA.1 records, and connect certificates, products, and batches to a COA Scan result that can be independently reviewed.
