Lucia allows you to anonymously check in at events using QR code based tracing.
New in version 0.2.0-rc1
Version 0.2.0-rc1

Make the app look more authentic
The Lucia app is capable of generating QR codes that users can use to check in at locations while not providing any personal data whatsoever. This is intended to safe-guard your privacy against a security hole in a certain system that might be forced upon you by some institutions.

QR Codes generated by Lucia can be presented to a staff member at the location to scan it from your smartphone. It will be considered valid by the check-in system. It does not, however, contain any personal data about you.
