Always ensure there’s a secure connection before logging in (https, lock icon, certificate owner) and that the domain name is correct.
The data required depends on the partner. You will be shown what data is required and asked to confirm it before each transfer of data. Under no circumstances will data relating to your account, transactions or creditworthiness be transferred.
The data will be stored for as long as is necessary for the fulfilment of the contract and for legal reasons. This is the responsibility of the partner.
The partner undertakes vis-à-vis PostFinance and you as the customer to use the data solely for the stated purpose (e. g. the conclusion of a contract).

An “electronic signature” is data that is attached to an electronic document to confirm the signature of the document.
A qualified signature is a form of certificate regulated by law that replaces signing by hand in legal communications, if this is allowed for in legal provisions or has been agreed between parties.
With the “Bankident PostFinance” solution, advanced and qualified electronic signatures can be created in accordance with the “Federal Act on Electronic Signatures” (ESigA). Creating a qualified electronic signature is only possible for customers who already have a PostFinance account.
To create a qualified signature using “Bankident PostFinance”, several preconditions must be fulfilled. Customers must be identified at a Swiss Post branch or PostFinance branch with a passport or identity card that permits entry to Switzerland from an EU or EFTA country. The customer must also use e-finance and the PostFinance App, including the push notifications function. If the customer does not fulfil certain criteria, our signature providers who generate the electronic signature cannot issue a certificate, and the customer must use an alternative identification method. In these cases, a qualified electronic signature cannot be issued, and “Bankident PostFinance” does not work.
The signature providers SwissSign or Swisscom Trust Services are responsible for the activation of partners who offer Bankident PostFinance. For a detailed answer, please contact the relevant signature provider directly.
