Scanning & Claims

Learn how to add verification claims to product pages using QR codes or manual entry.

What is a Claim?

A claim links a TAGBASE verification to a specific webpage URL. When someone visits that page and opens the extension, they'll see the verification details.

Adding a Claim via QR Code

1. Navigate to the product page where you want to add a verification

2. Click the TAGBASE extension icon in your toolbar

3. Click "Add Claim" to open the scanner

4. Point your camera at the TAGBASE QR code on the product or certificate

5. Review the preview - you'll see the verification details before confirming

6. Click "Add Claim" to link the verification to the current page

Adding a Claim Manually

If you have a verification ID (e.g., vrf_ABC123xyz):

1. Click the TAGBASE extension icon

2. Click "Add Claim"

3. Enter the verification ID in the text field (or paste a TAGBASE URL)

4. Click "Continue" to preview the verification

5. Confirm to create the claim

Verification ID Formats

The extension accepts:

• Verification IDs: vrf_ABC123xyz

• TAGBASE URLs: https://tagbase.io/v/vrf_ABC123xyz

• QR codes containing either format

Managing Claims

• Claims are publicly visible to anyone with the extension

• Multiple claims can exist on the same URL

• Claims cannot be deleted once created (blockchain permanence)

Troubleshooting

Camera not working	Check browser permissions for camera access
QR code not scanning	Ensure good lighting and hold steady
