3G Proof for Employees

The University of Mannheim has established the Classroom Pass Center (CPC) to check and store the 3G proofs. All employees who work on campus must go to the Classroom Pass Center to verify their 3G proof. Depending on the type of proof, it may be necessary to visit the Classroom Pass Center once, repeatedly or daily. The proof will then be stored in the web application Checkin that is only used by the university.

Please go to https://checkin.uni-mannheim.de and login with your Uni-ID and the corresponding password to check or present your proof. Under “Show 2G/3G status”, you will see your status and the expiration date.
