I think the best part are when the barcode is in a obvious easy to scan area like the forehead and displays detailed data about you like your blood type or name...then goes to more personal detail like number of times you've had sex, coloration, scent and extremely detailed descriptions and pictures of your holes, erogenous zones, menstrual cycles and the like for the public to know.
I also like the idea of biometric collars detailing when you're most fertile or whether you're already bred.
