An invoice will be sent to you via postal or electronic mail within the next weeks. This invoice is a valid invoice which may be submitted to the local tax and revenue office. All fees are due upon receipt of invoice/registration confirmation. Payment transfers must include invoice number. Payment is also accepted by credit card (Master-/Eurocard, American Express, VISA). In the case that you have transferred the registration fee shortly before the start of the congress, (up to 14 days prior to congress opening), we would like to ask you to please present your transfer remittance slip onsite.
