Mobile World Congress is full of all kinds of goodies, but I'm not sure of the usability of something of this nature; or more importantly, if anyone would opt to use it. Oberthur Technologies has announced SIMSense, a motion sensing SIM card that opens up a world of possibilities to those that don't have accelerometers in their wireless devices. The press release mentions examples like shaking the device to send a second caller an SMS stating the situation (i.e. "I'm not available at this time"), or having the device automatically call 911 when it detects a serious fall close to the body.
Regardless of whether the concept is actually utilized, the technology is certainly interesting. It could be useful for phones without an accelerometer, or devices marketed at older individuals, like the Jitterbug device. At present, no company has announced their intention to use the card.
