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.
16
), and select
OK
. The
digital signature icon disappears, and the service may display a confirmation of your purchase.
