Brand booth QR opens a capture form on the visitor's own phone. Entries are stored against the code and export as CSV, and a scan limit stops the booth once it has taken as many as it planned for.
A capture form sits in front of the booth's destination: the first scan from a phone shows the fields the sponsor defined, and every submission is stored against that code for the sponsor to read or export as CSV from the panel. The form page is plain and light enough for a festival's choked cell network. Later scans from the same phone skip the form and go straight through to the sponsor's page, each one firing a scan webhook with its time and country.
Free tier includes 1 standard QR code. Upgrade to the paid Eternal tier for blockchain permanence and the recovery key.
