A QR code is a machine-readable graphic that contains information, typically a website URL. Your ORCID iD QR code is unique to you and it represents your ORCID iD. Anyone who scans it with a QR code reader such as a mobile phone will be sent to your public ORCID record.
You can download your ORCID iD QR code from Account Settings > Sharing and display it anywhere you want your ORCID iD to be found.
