"Hackers have released source code that allows the 'backup' of RFID-protected passports, although the tool can potentially be used to create fake or cloned documents. The Hacker's Choice, a non-commercial group of computer security experts, has released a video showing a cloned passport being approved by a security scanner at a Dutch airport. When the reader scans the passport, it is revealed to belong to one Elvis Aaron Presley, complete with picture. Reports of the hackers serenading security staff with 'Are You Clonesome Tonight' are unconfirmed."
