Digital signature

You can make digital signatures with your phone if your SIM card has a security module. The signature
can be traced back to you via the private key on the security module and the user certificate that was
used to perform the signature. Using the digital signature can be the same as signing your name to a
paper bill, contract or other document.

To make a digital signature, select a link on a page, for example, the title of the book you want to buy
and its price. The text to sign (possibly including amount, date, etc.) will be shown.

Check that the header text is

Read

and that the digital signature icon

is shown.

Note: If the digital signature icon does not appear, there is a security breach, and you should
not enter any personal data such as your signing PIN.
