Digital signature

You can create digital signatures with your phone if your SIM card has a security module. The digital signature is the same as

signing your name to a paper bill, contract, or other document.
To create 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 be signed is shown and 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; do 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, and enter the signing PIN. The digital signature icon disappears, and the service may

display a confirmation of your purchase.
