Digital signature
You can make digital signatures with your phone. The signature can be traced 
back to you via the private key on the security module and the user certificate that 
was used to perform the signature. 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 (possibly including amount, 
date, etc.) will be shown.
Check that the header text is

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 then you can select 
Sign
.
Note: The text may not fit within a single screen. Therefore, make sure to 
scroll through and read all of the text before signing.

and the service may display a confirmation of your purchase.
