The signature can be traced back to you by the private key on the securitymodule and the user certificate that was used to perform the signature. Using thedigital 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 thebook that you want to buy and its price). The text to sign (possibly includingamount, date, etc.) is shown.Check that the header text is Read and that the digital signature icon is shown.Note: If the digital signature icon does not appear, there is a securitybreach, and you should not enter any personal data such as your signing PIN.The text may not fit within a single screen.
