Seagate Backup Plus Slim External USB 3.0 2TB Hard Drive Review
NB-30 BatteryFree Wireless Optical Mouse - NB-30 BatteryFree Wireless Optical Mouse
Tue, February 22 2005 | 2:33PM | PermaLink Feedback?
A4 Tech has created quite an interesting little gadget with their BatteryFree Wireless Optical Mouse. The mouse uses RFID technology to communicate position and button states to a mouse pad which plugs into your USB port. Even more interestingly, the pad transmits power to the mouse through inductance, so that the mouse needs no batteries for power. This results in a mouse with no wires leading out of it and which is far lighter than conventional wireless mice. In fact, it's a bit lighter than my conventional wired optical mouse. The RFID technology makes it much less likely than Bluetooth that you will ever have interference from other devices, but it does require the use of the pad. For some this may not seem to meet the full definition of "wireless".
