Payments will be made by credit card; they will be carried out through the secure Paypal or Stripe systems which use the SSL "Secure Socket Layer" protocol so that the information transmitted is encrypted by software and that no third party can take cognizance of it during transport on the network.
To pay via Paypal or Stripe, it is not necessary to have a Paypal account. All you need to do is fill in your details at the time of payment. We never have access to your bank details.
