The simplest and easiest way to top up your card is by using Autoload. You can replenish the credit on your student/employee pass directly at the till as soon as the card credit falls below a certain set limit.
You can use the EC card to revalue your student/staff ID card at the revalue machines using an EC card in all major Studierendenwerk facilities. You do not need to enter your PIN code for this (ELV procedure). The minimum amount that can be revalorised using an EC card is €5.00, the highest amount is €50.00.
In addition, it is possible to revalue directly at certain cash registers using an EC or credit card or Google-Pay, Apple-Pay.
Cash revalue is possible at the University Library in Tübingen. The cash revalue machine is located in the back of the foyer near the lockers. It accepts bills in denominations of 5, 10, 20, and 50 €.
