Digital signature

You can make digital signatures
with your phone if your SIM card
has a security module. 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, such as the title
of the book you want to buy and
its price. The text to sign is
displayed, which may include the
amount and date.
Check that the header text is
and that the digital signature icon
is shown.
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.
To sign the text, read all of the text
first, and select Sign.
The text may not fit within a single
screen. Therefore, make sure to
scroll through and read all of the
text before signing.
Select the user certificate you
want to use. Enter the signing PIN
(see "Access codes"
select OK. The digital signature
icon disappears, and the service
may display a confirmation of your
purchase.
