ECUS (Electronic Card University of Stuttgart) is the University of Stuttgart’s student ID card. This is a plastic chip card with a passport photo that is issued during enrolment. The card has a RFID chip that can be used for a range of applications and is valid for one semester, issued in tandem with the ECUS stamp.
The ECUS is valid for one semester and is validated with the ECUS stamp, which must be printed out after enrolling/re-registering for the relevant semester on C@MPUS. The VVS semester stamp, which can be printed off from the SSB ticket shop, is also needed to use the ECUS as a VVS ticket after 6 pm until close of operations and at weekends and on public holidays.
There are three versions of the ECUS:
- Current version 3: Since the summer semester 2018, all newly enrolled students will be given an ECUS with the new corporate design and the chip “Mifare DESFire” (see above).
- Version 2: Until the winter semester 2017/18, all newly enrolled students received the earlier version of the ECUS with the chip “Mifare DESFire”. This version of the ECUS either has the chip name next to the photo, or a dot after the word “Semestermarke”.
- Version 1: Until the end of 2013, the ECUS was fitted with the chip “Mifare Classic”. This version of the ECUS was not marked and after the end of the summer semester 2013, this version was only issued as a replacement.
You will receive your student ID (ECUS) by post (if you do not already have one) as part of the enrollment process. However, your ECUS card will only be shipped within Germany. We will only send it once you have entered your German address as your correspondence address (university address) in C@MPUS.
ECUS is valid as student identification in conjunction with the ECUS semester stamp, which you must print from your C@MPUS account each semester after you have successfully enrolled and received confirmation of your enrollment.
The ECUS functions have already been activated for the current semester. If you wish to continue to use the functions digital wallet and key card for buildings you must extend the card’s validity at the beginning of each semester. You must re-register to be able to extend the card’s validity. The ECUS can thus only be validated after you have successfully re-registered for the next semester. A further requirement is that the ECUS is not bent, damaged, dirty and is free of stickers.
Please be aware: The ECUS version 1 must be pre-coded before first use so that all functions can be used. This is not necessary for ECUS versions 2 and 3.
Further information about precoding and validation can be found in the "functions" window.
ECUS in combination with an up-to-date ECUS stamp identifies you as a University of Stuttgart student. At the university, this can be used as an identity card, but it is not a replacement for your official identity documents!
Thanks to its integrated RFID chip, the ECUS can be used for the following applications:
- Digital wallet for the canteen, cafeteria and photocopiers ("paying by chip")
The ECUS can be used as a digital payment method in the canteen and cafeteria, as well as for scanning, copying and printing on machines from the company Konica-Minolta. In the canteen and cafeterias at Studierendenwerk Stuttgart, all checkouts are equipped with white scanners. To pay, simply lay the ECUS on the scanner until payment has been completed. Photocopiers from the company Konica-Minolta are also equipped with scanners that read the ECUS.
Please note: The wallet function on ECUS version 1 must be pre-coded by Studierendenwerk Stuttgart. This can be carried out at the Studierendenwerk info-points in the canteens on the Vaihingen and Stadtmitte campuses. Precoding is not necessary for ECUS versions 2 and 3.
Further information about validation, initialization and topping up your ECUS wallet can be found on the Studierendenwerk webpage (under the headline "Information for students and staff of the University of Stuttgart" at the end of the website).
- Library ID card
With the ECUS, you can also borrow books from University of Stuttgart libraries. In order to borrow books from the university library, your UB account number is saved on the ECUS chip, for the libraries belonging to the various institutions the ECUS is used as a form of photo ID.
Furthermore, if you display a current ECUS card with a ECUS stamp at many other libraries, e.g. the Württembergischen Landesbibliothek, you will also receive a free library card.
- Key card for buildings and rooms at the university (ECUS-/KABA access system)
The ECUS has an access application from the company KABA that allows the card to be used as a key card for buildings and rooms at the university. You can enquire on-site which buildings and rooms use this application.
Please note: The access application for the ECUS version 1 must be pre-coded. Instructions and the location of the coding station can be found in the information on accessing rooms using your student ID card: Raumzutritt per Studierendenausweis [de]. This is not required for versions 2 and 3.
Access rights are issued by the relevant faculties and departments either once or each semester. For use via the white scanners (offline access), the ECUS must be validated on every day of use. Instructions and the locations of the validation terminals can also be found in the above mentioned manual. Validation is not required when accessing rooms using the black scanners (online access).
If problems arise with coding/validating the ECUS or when accessing buildings/rooms, please first read the information on accessing rooms using your student ID card: Raumzutritt per Studierendenausweis [de]. If you do not find a solution to your problem, please email the Department VI – Engineering and Constructions [de] with the following information:
- Your student number
- Number of the scanner (located on the left edge), or alternative building and room number
- "Reaction" of the scanner with date and time
- if applicable, any further information about the problem
- VVS semester stamp and VVS-StudiTicket
The VVS (Verkehrs- und Tarifverbund Stuttgart GmbH) organizes public transport on buses, trams and trains in Stuttgart. If you wish to use the VVS daily from 6 p.m. until close of operations, and all day on weekends and public holidays you need a current VVS semester stamp and an official photo ID. The ECUS must be carried with you.
If required, you can print the VVS semester stamp yourself for each semester from the SSB website, or download it to your mobile phone using the app, after you have received the enrollment/re-registration confirmation. It will be possible to print/download the stamp from March/September for the following semester and this can be done with (for printing or downloading) or without registering (for print only, not download) on the SSB website. The printout/download of the VVS semester stamp is free of charge.

You can purchase your StudiTicket over the counter, or via the SSB website. To purchase a StudiTicket over the counter you will need your ECUS and a valid VVS semester stamp as proof that you are entitled to buy a StudiTicket.
- Identification for numerous student discounts
The ECUS in combination with a current ECUS stamp proves that you are a student at the University of Stuttgart and makes you eligible for various student discounts in both public and private institutions (e.g. cinema, swimming baths, library). Please note that the relevant institution and not the University of Stuttgart are responsible for the conditions of any discounts (e.g. discount amount, age limits).
You will be issued a new ECUS card under the following circumstances
- If your ECUS card is visually and mechanically in working order but can no longer be read electronically.
- Test that the card can be read at one of Studierendenwerk Stuttgart’s info points (e.g. in the canteen). If this shows that the card is defect you will receive an "attestation for a replacement card".
- Please upload a current photo on C@MPUS and check the up-to-dateness of your postal address.
- Please send the attestation and the information whether money was in the digital wallet via contact form to Division 3 - Students' Affairs and you will receive a new ECUS card free of charge.
- If your ECUS is damaged or if it has been lost or stolen.
- As soon as the university cash office reopens, you can purchase a new one for 15.00 euros. Please pay this fee at the university cashier’s offices before collecting your card. The university cashier’s office will give you a receipt [de] (PDF) that you can upload via contact form to receive your new card.
- Because the university cash office is temporarily closed please send us your request and the information whether money was in the digital wallet via contact form.
- Please upload a current photo on C@MPUS and check the up-to-dateness of your postal address.
You may update your postal address (in German: Korrespondenzadresse (Studienadresse)) and your photo: the photo via C@MPUS-Business-Card, the address via "my current/home address". Please inform us through your request, whether you checked and updated both of them.
Functions: It usually takes 24 hours, but in exceptional circumstances (e.g. during internal maintenance periods) it may take around 2-14 days until all functions have been activated and can be used. If activation still isn’t completed after 14 days please email the Department VI – Engineering and Constructions.
Wallet function ("paying with the chip card"): If there was money in the digital wallet of the cancelled card the credit can be transferred onto the replacement card or paid out in cash at one of the Studierendenwerk Stuttgart info points (e.g. in the canteens). In order to do this, you will be issued confirmation that the old card and ID chip have been cancelled from the Student Service and Examinations Office. The credit will then be determined via the chip ID at the SWS info point and either transferred or paid out in cash.
Please note, if you lose your card: no data is saved on the ECUS chip that could provide information about where you live etc. If money has been paid onto the card and another person uses the money we are unfortunately unable to refund the money lost.
The ECUS is made of plastic and is the same format as a traditional plastic card. But due to the integrated RFID chip it is more sensitive than other cards. Please follow these simple rules to care for your card adequately.
- Don’t bend, fold or deform your card!
- Don’t keep your card in your back pocket!
- Store your card away from coins in your wallet or purse!
- Don’t let your card get too hot or leave it in the sun (e.g. lying on your desk)!
- Don’t clean your card with chemicals or wash it in the washing machine!
- Don’t write on the card or stick anything on it!
The best way to clean your ECUS card is with a damp cotton cloth and no cleaning agents. If your ECUS stops working, please contact the Student Service and Examinations Office.
The RFID chips "Mifare Classic" and "Mifare DESFire" differ from each other as follows:
- Memory: Mifare Classic 1 KB, Mifare DESFire 8 KB.
- Security: The chip encryption of the "Mifare Classic" (ECUS version 1) is unsafe, which is why this chip can be "cloned". However, this is very unlikely to have any serious consequences because the test systems recognize any unusual activity from a shadow account and block the ECUS.
- Integrated antennae: The transmitter range of the ECUS is maximum 10 cm; the ECUS cannot be located and read from a greater distance. Furthermore, for the ECUS versions 2 and 3 wire and data transfer are also encrypted. The chip is provided with electricity via the scanner; the chip itself is "passive".
- Wallet and KABA access applications: The wallet and access applications of the Ecus version 1 must be pre-coded on two different stations:
