Online payment 

Payments for the registration fees for CEST2021 are processed through the eCommerce service provided by Alpha Bank Greece (www.alpha.gr/en). Through Alpha Bank eCommerce we are accepting Credit card payments and bank transfers. Payment confirmation is sent by e-mail to the emails address provided by the Customer soon after acceptance of the payment (by credit card) has been processed by the bank. A receipt or invoice will be issued after your payment and will be delivered to the e-mail address provided during the payment within a week.

 

Please keep in mind that online registration is mandatory in order for your payment to be confirmed and valid. 

In case you require a “on - Credit invoice” you should click on “Invoice” while filling out the billing information. CEST does not have access or withholds any credit card information given during the payment. The system used is a secure system handled entirely by Alpha Bank Greece.
