Digital signature

With the digital signature functionality you can, for example, digitally sign a bill or a financial
contract. The signature can be traced back to you via the private key and the associated certificate that
was used to perform the signature, so signing using the digital signature is the same as signing your
name to a paper bill, contract or other document.

A digital signature is initiated by a code embedded in a WAP page. Select a link, for example, the title
of the book you want to buy and its price. The digital signature procedure starts and shows the text to
sign. At this point the header text is


and the digital signature icon

is shown.
