A4 Tech Corp. launched the NB-30 BattryFREE Wireless Optical Mouse, powered by a special RFID mousepad. By using RFID the company managed to create a more environmentally friendly mouse, with no batteries to dispose of after use.
The mousepad is connected to a computer via USB and while connected it delivers a low voltage, just enough to activate the RFID chip inside the mouse. When the Wireless Optical Mouse is placed on top of its pad it will automatically start and be ready for use.
According to the company, since there are no batteries inside the BattryFREE Wireless Optical Mouse it could be designed with a much lighter but more durable framework, providing an ergonomic handling and easy portability. The mouse also sports a new U-Shaped Scrolling Wheel, based on the human finger ergonomics.
