Smart IDs: PetHub

This little company makes scannable ID tags that use QR codes. So, if Brutus skidaddles, whoever finds him can use the code to pull up his online profile--and get in touch with his owner. The company's Beta program launched in September, 2010. Two and a half years later, PetHub has launched in Netherlands, Germany, and France.
