Payment methods for payment of GAeF membership fees

SEPA direct debit (SEPA - Lastschriftverfahren)

This payment method enables automatic yearly payment of your membership fees once you have filled in and signed this SEPA mandate. General information on SEPA direct debit can be found at the webpages of the Deutsche Bundesbank.

Only three steps are needed to profit from this easy way of payment:
1. Please download the SEPA mandate from
2. Please fill in all given fields - use your membership number as the mandate reference.
3. Please send the filled and signed form via mail to our treasurer - your original signature is needed! 

You will receive a confirmation about this payment method including your individual SEPA mandate reference and the Creditor identifier of GAeF. For each year your invoice will indicate the date of debit withdrawal from your bank account. This notification will be done at least 14 days prior to the withdrawal which gives you time to check that your bank account data are still correct and that enough money is present on your account.  

By agreeing to these terms you agree that any charges for non valid bank accounts or due to insolvency have to be covered by you and will be additionally invoiced by GAeF.

SEPA bank transfer (SEPA - Überweisung)

Within the euro zone (+ some additional countries) you can pay your membership fees by SEPA bank transfer. Please refer to your invoice for details on bank account information. Please make sure you pay your dues within 30 days after receipt of your invoice. 

Credit card

If you wish to pay by credit card you need to fill in, sign and send the credit card form to the treasurer. The credit card form is automatically attached to all invoices for countries that are not part of the SEPA system. If you are residing in a country where SEPA is available but you still would like to pay by credit card please contact the treasurer.
