The FHWS Card

The Julius Maximilian University of Würzburg, the University of Music Würzburg and the University of Applied Sciences Würzburg-Schweinfurt introduced a multifunction card with joint functions in co-operation with the Studentenwerk Würzburg in the winter term of 2011/12.

The multifunction card combines the following functions:

  • Student ID card
  • Library card (FHWS and university library)
  • Electronic purse of the Studentenwerk Würzburg (formerly canteen card) (means of cashless payment)
  • Electronic access to the participating institutions
  • Semester ticket VVM (only for students of the department in Würzburg)
  • Print and copy card

Advertisers: Sparkasse Mainfranken, Mainpost, WVV

The chip card contains a DESFire chip (RFID) and thus is a non-contact card. It does not require any contact strips. 
The validity period of the card is printed on its front side and is electronically saved on the chip.

The validity period and the semester ticket will be printed on the thermo read write strip (TRW) on the front side of the card.

The imprinting process is carried out by validation machines. At the beginning of each term, the card must be validated at one of these validation machines.

Once the card has been inserted, the machine will first check the validity of the card, then scan the background system and imprint the TRW strip with the new validity date and the semester ticket. The latter is only applicable for students of the department in Würzburg. The machine will simultaneously update the data on the chip.

The process takes about 2-3 seconds / card

Locations of the validation machines

  • Röntgenring 8, building B in the foyer
  • Münzstraße 12, in the foyer in front of the ALDI theatre
  • Sanderheinrichsleitenweg in front of the cafeteria


  • Behind the auditorium (left and right), first floor

In the upper right corner you see the electronic chip. Stemming from the chip, the antenna wires are placed along the frame of the card.

  • Please keep your card in a solid card case. It is not advisable to keep the card inside your wallet - the card might get bended out of shape. In this case, the ring-shaped antenna or the chip could get damaged. Diagonal bending can be very damaging.
  • Do not expose the card to high temperatures (of over 60° celcius)
    (extremely critical e.g. glove compartment and on top of the car dashboard panel). The validity date can become illegible or the card can lose its shape.
  • Chip cards, which have been exposed to high electromagnetic fields (e.g. amplifiers, speakers at the club) also run the risk of being damaged or destroyed.
  • Should the card become unusable due to improper handling, a fee of € 20.00 will be charged. Please treat your FHWS-Card with care.

Note: In the event of loss, the money is lost as well.

The card is a chip card, which is based on MIFARE DESFire technology. On the card and when communicating, current cryptographic algorithms (3DES) are being used.

The University of Applied Sciences Würzburg-Schweinfurt saves the data in line with the administration of students. Regarding the external use, e.g. means of cashless payment (canteen), the respective institutions can only read the data saved on the card.

Each card has its own card serial number, which is being saved in the system for all so-called cash point transactions. In addition, only a personal code number (student, employee, guest) and a university code number (Studentenwerk, University of Würzburg, University of Music, University of Applied Sciences Würzburg-Schweinfurt) are saved on the card.

The Studentenwerk or the University of Würzburg has no access to personal data (e.g. name, address, student ID number) and does not need this information either.

On the premises of the University of Applied Sciences Würzburg-Schweinfurt, access data will not be registered.

The card contains the following data:

Imprinted on the card:

  • Picture
  • Surname, name
  • Student ID number
  • FHWS library user number as bar code
  • FHWS library user number in plaintext
  • Chip card serial number
  • Validity date (varies)
  • Semester ticket (varies)

Electronically saved data:

  • Chip card number
  • Electronic purse of the Studentenwerk Würzburg
  • Personal code number for the electronic purse (student, employee, guest)
  • Validity date
  • FH library user number
  • Right of access
  • Complimentary credit management for printing / copying payment

Jede Karte hat eine eigene Karten-Seriennummer, die bei allen Vorgängen in den sogenannten Kassentransaktionen im System abgespeichert wird. Weiterhin ist auf der Karte lediglich ein Personenkennzeichen (Studierender, Mitarbeiter, Gast) und ein Hochschulkennzeichen (Studentenwerk, Universität, Hochschule für Musik, Hochschule Würzburg-Schweinfurt) hinterlegt.
Auf personenbezogene Daten (wie Name, Anschrift, Matrikel-Nummer) hat das Studentenwerk oder die Universität Würzburg keinen Zugriff.

Im Bereich der Hochschule Würzburg-Schweinfurt erfolgt keine Registrierung der der Zugangsdaten.
