Problems with your chip card
Most of the time, your red or yellow chip card from the Studierendenwerk Karlsruhe is very reliable with normal handling. Most students can use their card trouble-free for several years. The same applies to the student ID cards of the universities with an integrated pay-chip. Nevertheless, it may happen that the chip is damaged or no longer readable, or other problems may arise while trying to use the card.
