Networking QR-Code app
A QR code is generated from your personal networking profile in the app. This can be scanned by other app users on site at the convention trade fair, and a link is automatically created between the networking profiles in the app, which can be found under Contacts.
Furthermore, you can export your list of contacts after the fair. Just click on download all contacts
When you make changes, they are not immediately visible in the app. This requires either closing the app briefly and reopening it, or manually updating the app via the drop-down menu - Update data.
