Many other countries in Europe can do it as well. The electronic identity cards of Austria, Belgium, Estonia, Finland, Germany, Italy, Liechtenstein, Lithuania, Portugal and Spain all have a digital signature application which, upon activation, enables the bearer to authenticate the card using their confidential PIN. Consequently they can, at least theoretically, authenticate documents to satisfy any third party that the document's not been altered after being digitally signed. This application uses a registered certificate in conjunction with public/private key pairs so these enhanced cards do not necessarily have to participate in online transactions.
