react-innovatielab-identity-qr

Introduction

A React component for generating a QR code that represents a question about someones InnovatieLab identity. Questions are registered on the innovatielab.nl domain. For each question an ID is generated which should be included on the questioners page. Based on this ID a QR code is generated. The user will scan this QR code with his Innovatielab identity App (follow this link on your Smart Phone). If the user agrees to the information exchange, the questioner will receive (part of) the users identity.

Creating a question happens after authentication, so the questioners identity is assured. Scanning a QR code by the user also happens after authentication, which assures the users identity. So both parties know for sure who they are dealing with.
