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, for example, the title
of the book you want to buy and its
price. The text to sign is shown,
which may include the amount and
date.
Check that the header text is
Read
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”
p.
xii
), and select
OK
.
The digital signature icon
disappears, and the service may
display a confirmation of your
purchase.
