The YIP Smart Tag is an engravable ID Tag and tracker that helps you locate your furbabies right on your Samsung Galaxy phone. Your tag communicates with hundreds of millions of Samsung Galaxy smartphones, providing virtually unlimited range. In just a few easy steps, you can add your YIP Smart Tag to the Samsung SmartThings app on your Samsung Galaxy smartphone. During those stressful moments, go to the Samsung SmartThings app and see on the map where your furbaby is or turn on Lost Mode and your Galaxy smartphone will notify you when your smart tag comes within range of another Samsung Galaxy device. IMPORTANT: You will receive the YIP Smart Tag with a blank name plate. Please follow the instructions inside of the package to order your engraved name plate at no additional cost. The YIP Smart Tag uses a coin cell battery. Keep out of reach of children. If a battery is swallowed, immediately see a doctor.
