These rings add a gripping new meaning to â€œshake on itâ€.
Each â€œsmartâ€ ring stores your details, transferred there via a digital business card the size of a credit card. To pass along your details to a new business associate, simply shake hands, instead of handing over a traditional business card. It also displays a contact list of all the people you've exchanged information with â€“ personal info, contact numbers, and for those with short memories, the date you met. All information is customizable, and transferable to anyone wearing another â€œsmartâ€ ring.
To view the information, sync the ring back to the digital business card. No batteries required either; the rings are juiced up by body heat. The entire business world will have to get one of these for the trend to take off in a big way, but even from where I'm sitting, the possibilities are mind-blowing.
