# Multifunctional Chip Card

The **Multifunctional Chip Card** is a versatile smart card issued to members of the Universität Greifswald, serving as a primary tool for identification, payment, and physical access.

## Core Functions
- **Identification**: Acts as a [[mitarbeiter-ausweis]] (staff ID) featuring a photo and name.
- **Payment**: Integrates a [[bezahlboerse]] managed by the [[studentenwerk]] for use in university cafeterias.
- **Access Control**: Serves as the credential for the [[elektronisches-zutrittskontrollsystem-ezks]].

## Access Control Specifications
When used for building access, the card operates under the following technical and administrative rules:
- **Update Cycle**: To maintain access to "offline" locks, the card must be updated at an "online" lock (Update Point) at least once every **7 days**.
- **Data Storage**: The card stores a unique ID and access rights; no personal data is stored on the chip itself.
- **Revocation**: Physical access is automatically revoked the day after an employment contract ends, regardless of whether the URZ account remains active.

## Card Loss and Blocking
In the event of loss, the card must be reported immediately to prevent unauthorized access.
- **Hotline**: +49 3834 420 2273 (or +49 3834 420 CARD).
- **Ticket System**: Reports can be made via the [[groupware]] ticket system.
- **Requirement**: The user's URZ username is required to block the card.
