Dutch banks have not yet introduced a uniform payment system to replace the chipknip electronic cash system, which will be discontinued with effect from 1 January 2015. This makes it very difficult to devise an effective digital method of making small payments on [organisation location, eq. campus]. Students from abroad may encounter particular problems in this connection. A closed payment system, applicable only on [organisation location, eq. campus], deals with this issue and is also secure.
Xafax, the external organization that manages Netpay, guarantees the safety of your money. The money on your e-wallet is administered by a separate organization, Stichting Derdengelden. Neither Aeres nor Xafax has access to your money.
No. The money in your e-wallet is administered by an independent foundation to which neither Aeres nor the external system manager (Xafax) has access. It does not yield any interest, and it is not invested. It remains your money. Any unused balance in an e-wallet that has not been transferred before the Aeres account was discontinued will be donated to the Aeres International Student Fund.
The University of Amsterdam and Amsterdam University of Applied Sciences have already successfully introduced this system.


You can top up either online or at a physical top-up station. Online top-up will be possible via myNetPay, where you can log on using your Aeres account. The location of the top-up station can be asked at the informationdesk. If you find you are unable to top up the credit on your e-wallet, you should contact us by using the form provided for this purpose in myNetPay at the Contact-page. You need to link your e-wallet to your Aeres card before you make your first payment with your e-wallet. This can be done at one of the printers or at the physical top-up point(but not at the vending machines). It only needs to be done once.
If you find you are unable to top up the credit on your e-wallet, you should contact Xafax using the form provided for this purpose in myNetPay.
No, You can't transfer credit in your e-wallet back into your bank account at the moment.
It may happen that a Aeres account has been discontinued, but that there is a credit balance in the e-wallet. We do our best to prevent this situation by repeatedly reminding the student or employee whose account is about to expire. If any credit is not retransferred, this money will be donated to the Aeres International Student Fund.
The minimum amount of credit that you can add to your e-wallet is € 10.00


It will also be possible to use other cards to make payments on our campus, as long as they have a Mifare chip with sufficient credit balance on it. Examples of such cards are the OV-chipkaart (the smart card used to pay for all forms of public transport in the Netherlands), the NS Business card issued by Dutch Railways and various library cards. All these cards can thus be used in the payment system on our campus.
Your credit balance is stored in digital form on your e-wallet, and not on your Aeres card itself. This means that the credit balance is linked with your personal account. If your Aeres card is lost or stolen, you should disconnect the card from your e-wallet as quickly as possible. Disconnecting your card is possible at the printers by choosing the option "delete a card from your login account". Losses incurred before you disconnect the card from your e-wallet are your own responsibility.
You can use myNetPay, the system you use to top up your e-wallet, to view your transaction history. This allows you to see precisely how much you have paid on various occasions, when, and for what (printer usage, soft drinks, coffee, snacks etc.).


An external organization, Xafax, works together with Aeres to implement this closed payment system. Xafax has no access to your personal data. Only your [organisation] username, your credit balance and the number of the pass linked to your e-wallet are known in Netpay, the system you use to manage your e-wallet. Xafax manages Netpay, but cannot access the above-mentioned data without your permission.
