Seiko Epson has developed a paper-thin fingerprint sensor measuring 0.2 millimeter in thickness, which may help bring an extra level of security to a range of items in the future. When touched, the sensor reads fingerprint patterns based on the faint electric current emanating from the user's fingertip.

The fingerprint sensor's ultrathin profile means it can easily be incorporated into a variety of commonly used items. Among the applications that Seiko Epson is targeting are self-authenticating credit cards, in which a tiny on-card processor is used to compare the captured fingerprint data with the user's fingerprint data stored in an embedded memory. A non-matching fingerprint would render the card unusable, preventing abuse in the case of loss or theft.

The company aims to commercialize the sensor by 2010.
