A4Tech Battery-Free Wireless Optical Mouse

@ 2004/11/29
There are many wireless mice on the market that use either RF or bluetooth to communicate with your PC. However, all these mice require one thing that can be quite costly over time...batteries. If the input device is cordless, it requires batteries in order for it to function right? Well, not necessarily. A4Tech has released a highly innovative new wireless mouse that uses a slightly different method for power. This battery-free mouse uses RFID to communicate with the included "special" mouse pad. Let's have a closer look at this rather interesting new product.
