If you're passing through a dog park in Boston in the coming months and happen to catch a glimpse of a funny little device hanging off a pooch's collar, don't be surprised. A startup called SNIF Labs is gearing up to beta test a technology designed to help dogs--and their owners--become better acquainted.
SNIF Labs--the company's name is short for Social Networking in Fur--is developing what its website calls "a custom radio communications protocol" that allows special tags dogs wear on their collars to swap dog and owner information with other SNIF-tag users. When two dogs wearing tags come within range of each other, the tags start to swap dog and even owner information.
Once owners are back home and using the company's social-networking service, they can trade information about their dogs and themselves online.
