# Personalized Key Cards

At the Universität Greifswald, the [[multifunktionale-chipkarte]] used for the [[elektronisches-zutrittskontrollsystem-ezks]] is a **personalized key card**. 

## Implementation
Personalization consists of printing the following identification markers directly on the card:
- User's full name.
- A photograph of the user.
- The user's [[zentraler-nutzeraccount]] (URZ username).

## Security Rationale
While there is a common perception that printing personal data on a key card reduces security (by identifying the owner to a finder), the university adopts the recommendation of data protection experts that personalization actually **increases security**. This is because it facilitates the immediate identification of the card's owner and encourages the prompt reporting of lost cards.
