In the US this year, there was outrage when people in job interviews and in schools were asked to hand over their Facebook passwords. Dwyer said that in the future and with the arrival of the semantic web and linkable data there is a danger that insurance companies may be able to find out if applicants had done a search for keywords like cancer stretching back 15 years.

Smart card transactions can be quicker, because the terminal and card communicate with each other -- the terminal verifying that the card is authentic and vice versa -- instead of the terminal having to communicate via Internet or wireless with the card issuer to verify that the card is real and hasn't been reported lost or stolen, says Randy Vanderhoof, executive director of the Smart Card Alliance, a nonprofit organization that works to promote the adoption of smart card technology.

Also, when a card leaves the cardholder's physical presence, it can be compromised, using a hand-held information-stealing device called a skimmer,

in which information is encoded into a magnetic stripe on the back of the card, and the newer so-called smart cards, which contain a computer chip that holds information.
