Transactions in the passenger portal are made using the SSL (Secure Socket Layer) protocol with a digital certificate, which guarantees the confidentiality and integrity of the transmitted data. Data on payment cards, Blik or fast transfers are transmitted directly to the Tpay authorization server. There, the transaction is authenticated and authorized, which ensures complete security of online payments.
SSL is a network protocol that enables secure internet connections. It ensures data encryption, server authentication, and confidentiality of the information in transit. When the browser is connected to the Tpay service, algorithms and encryption keys are established, which then protect the information sent between the browser and the server. SSL is the main method for ensuring the security of online financial transactions.
