Secure Transactions

Stavros Ristanis Clinic has an agreement with Viva Wallet (Viva Payment Services SA) for the use of its system and its service in order to ensure the maximum possible level of security in your credit card transactions.

The customer completes his purchases in our e-shop.

When starting the payment process, it automatically goes to the special payment page of Viva Wallet. There he is informed about the amount of his debt and enters his card details.

The payment is processed with absolute security by a system of Viva Wallet, which automatically informs our e-shop about the transaction.

The customer is informed about the completion of his transaction by our e-shop.

Upon completion of the transaction, the customer returns to our e-shop.

Therefore, our doctor’s office does not keep any details of the card used during the payment.

We would also like to know that: Viva Wallet uses one of the most modern security standards in the world, having integrated the SHA-2 encryption algorithm in the digital certificates of its websites. Therefore, in order to make a transaction using a card, it is recommended that you have the latest versions of the browsers you use (Chrome, Mozilla, etc.) and the operating system of your mobile device (Android, Apple OS) installed.
