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, which may include the
amount and date, is displayed.
Check that the header text is Read and that the digital signature icon
is displayed.
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.
