RFID In Phone Controls Office Security System

DoCoMo has successfully developed an office security system that is based on RFID chips located in its cell phones. This system, known as Kaismart, allows cell phones to unlock doors, access computers and other networked peripherals, clock in and out, and even pay for your food. Woe to the person who actually loses his/her handset. I guess there are pros and cons to such convergence technology, but over-reliance on a single device isn’t necessarily a good thing either.
