For the security of your payments, we use secure Mercanet BNP services. According to the requirements of your bank you will be asked for a code. Often this code is sent via SMS. Verify that you have the mobile phone  that was registered  on your bank account. Your bank data will be encrypted during the transaction and we do not have knowledge  of it. Your bank data will never pass through our server. 

If you meet any problem with your payment contact us : +33 (0)1 41 14 45 27

You can also use Paypal even if you do not have a Paypal account. You do not have to create an account for this purpose. You will then choose the option "without registration"
