SSL certificates

PostFinance protects all actions in e-finance using strong encryption and a secure digital identity card. To do so, it uses Secure Sockets Layer (SSL) and Transport Layer Security (TLS) technology. The certification body is VeriSign.

SSL protects all your actions, from the initial connection right up until you logout. Even before you enter your user data, a certificate is displayed to confirm that you are connected securely and directly to PostFinance. Strong encryption in the background makes sure that none of the data you enter is altered before reaching PostFinance - and PostFinance alone.

In all modern browsers, you can tell that the current connection is protected by an EV-SSL certificate from the green font or green background in the address bar. You can double check that the certificate being used has not been altered by looking at the certificate fingerprint. A step by step guide can be found at ebas.ch

3-D Secure

For the protection of your credit cards and prepaid cards on the Internet

With 3-D Secure, the internationally recognized security standard for online payments using a credit card or prepaid card, you're even more secure when shopping online. Thanks to your own personal 3-D Secure password, you can identify yourself beyond doubt in online shops in the same way as when you use your PIN code in a shop or at an ATM.

3D Secure is a communication protocol designed to improve online payments and to enable the authentication of the card user by the credit card issuer. When paying at an online store, a credit card validation process is activated. If the credit card is considered valid, 3D Secure protocol security systems check the client's identity, resorting in real time to the credit card issuer. The issuer validates the client's identity and informs the store system that the card being used is legitimate.

The goal is to protect credit card users, minimising the possibility of fraudulent credit card use and improving the overall transaction performance. This protocol is used by Visa, with the « Verified by Visa » designation, and by Mastercard, with the « SecureCode » designation.
