How do I use the ID card in the BankID app?

When you tap “Show ID” in the app, a QR code is generated that can be scanned at the checkout in the store or at the place that needs to check your ID. When you need to generate a new QR code, you must verify yourself using facial recognition, fingerprint, or your phone’s PIN. The QR code is valid for 30 seconds, or until it has been scanned. If it is not scanned within 30 seconds, you must generate a new one.
