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.
