Loss and Locking of ID Card
If an ID card or the PIN letter get lost or have been accessed by a third party, the ID card has to be locked. You can communicate the loss of your ID card or your wish to lock the ID card by indicating your lock code.
Locking your ID card: https://www.uni-giessen.de/uni/chipkarte/sperrantrag.html, send a fax to the IT Service Centre: 0641/99-13019, or send a letter to the Registrar’s Office, or go to the Registrar’s Office.
You will need to give your lock code, name, address, and – if possible – ID card number. Should your lock code and ID card number not be available, please indicate this in your letter or fax. In this case you should at least give your telephone number.
If you do not explicitly indicate that you only want a temporary locking of the ID card (in case you think it might be possible to retrieve it), it will be finally locked. This necessitates the issue of a new ID card (€ 50, including refundable deposit) if you are responsible for the locking of the card due to loss of the ID card, PIN-letter or damage of the card. The electronic purse cannot be locked. Any person with access to the card can use the electronic purse.
