App registration and login process

To register, you need a card reader and your PostFinance Card. Register once in the PostFinance App. For all further access, you can use fingerprint or Face ID (for iPhone X only) or the password you have defined yourself.

  • Fast service password

    Choose a secure password with digits and letters or special characters. Make sure that nobody sees you entering your password and do not reveal your password to anyone. Change the password if you think that a third party knows it.

  • Login with fingerprint

    The Fingerprint technology is part of the iOS or Android operating system and is not provided by PostFinance. Fingerprint technology is used at your own risk. PostFinance has no influence on any security gaps in fingerprint technology. Please follow the tips below to use Touch ID securely:

    Protect your device

    Keep your device protected and do not give access to third parties.

    Deactivate the simple code (iPhone)

    The iPhone factory standard with the simple 4-digit numerical code is insufficient for financial transactions. Set up a complex code to unblock your iPhone at: Settings > Touch ID & Code > Deactivate simple code.

    Choose a secure code to unblock your device

    A complex code for unblocking your device should consist of digits and letters or special characters. Do not reveal the code to any third parties. Change the code if you think that a third party knows the code for unblocking your device.

    Select finger

    Clever attackers are able to make a copy of a fingerprint found on the screen and use it to log in. You should therefore save a fingerprint that cannot be found or is not often found on the screen, e.g. that of the middle or ring finger.

    Only your own fingerprints

    Once fingerprint has been activated in the fast service, anybody whose fingerprint has been saved will have access to the fast service. You should therefore only save your own fingerprints.

  • Login with Face ID
