LED used in biometric fingerprint detector

Taiwan-based technology developer UPEK has unveiled a new biometric fingerprint reader which utilises LEDs.
To be demonstrated at the Computex Trade Show in Taipei this week, the TouchLight technology allows biometric devices to prompt the user to perform activities such as swipe their finger or tell them if they are authorised or not through the use of LEDs.

The lighting also adds a "cool" factor, according to the company, and it could be added to consumer devices such as notebook PCs, mobile phones and other portable electronic equipment.

Vito Fabbrizio, senior director of original equipment manufacturer (OEM) marketing at UPEK, said: "We´ve made it easy for PC OEMs to incorporate LEDs by integrating them directly into the sensor package while also giving them the flexibility to design with external LEDs."

LED manufacturer Seoul Semiconductor recently announced an agreement with M-Vision for licensing patents for new portable ultraviolet LED forgery detection technology.
