You sign with BankID when you want to do something, for example, make a payment or transfer on the Internet bank, submit your tax return online or report that you are caring for a sick child. When you choose BankID to sign with on a website, a file signature window automatically opens in the BankID Security Application.
Check that the service provider is the one you expect and that the text presented conforms to what you want to do.
If you sign with BankID on file, or BankID on card with a card reader without PIN pad, a text field is shown for Password or PIN, where you enter your password or PIN.
Then click on the button Sign. If you sign with BankID on card and have a card reader with PIN pad, you will be requested to enter your PIN on the PIN pad.
On some web pages the text to sign is displayed on your cardreader's display, which the preceding dialog will inform you about.
