UPEK, a developer of biometric solutions, has unveiled their new fingerprint technology, called TouchLight that integrates light emitting diodes (LEDs) as a way for user prompting and feedback to fingerprint sensors. The LEDs are expected to be used for services such as letting a user know when they can swipe a finger or whether or not the sample has been accepted.

The technology has been designed with uses as either an embedded device or external fingerprint scanner primarily with computers. TouchLight will be demonstrated by UPEK at the Computrex Trade Show in Taipei, Taiwan this month.
