a) Payment method: register your bank account = SEPA direct debit mandate

 b) Settings: here you can set how much money per top-up should be transferred to your app as credit. One top-up per day is possible. So choose a realistic amount for at least one day. You determine the amount at which the cashier or checkout will ask you if you want to top up: ‘Top up by £xx if balance falls below £y.’

 c) Top-up: once a payment method has been stored, you can top up the app with the specified top-up amount by clicking on Top up now. Wait a few minutes and restart the app if necessary so that the new credit is displayed in the app. You will see it immediately in the transactions, which tells you that it has worked.

To pay, scan the QR code at the checkout or at the coffee machine. You can view the respective payment amount for your last purchases in the app at any time.

Yes, it can still be used.
However, recharging the card might become more difficult in the future, since we want to phase out cash completely in the long term. But there is also the autoload option for the card as a cashless top-up method.

StudiwerkMainz app – pay & more: 

You can also use the app as a guest (non-students, conference participants, visitors). It only takes a few minutes to set up. You enter a payment method and specify the top-up amount. You can have the remaining amount paid out to you.

Advantage: You can install the app wherever you want to use it, regardless of your location.

Guest card:

You can purchase the guest card for a fee of £5 from the guest card vending machine. To do this, you need a £5 note and must go to a location where one of these machines is located. You can then top up the card with cash (5, 10 or 20 euro notes). To have the remaining balance paid out, you must send an email and have the remaining balance transferred to you.

Advantage: Cash 

Please be aware that recharging the card might become more difficult in the future, since we want to phase out cash completely in the long term. But there is also the autoload option for the card as a cashless top-up method.
