Smart Ring Accessory for Tesla Model 3 RFID Technology Key Card Key Fob Replacement
Your Tesla Model 3 comes with an RFID reader implanted into the center of driver-side B-beam. The term RFID refers to radio-frequency identification. The implanted RFID reader uses electromagnetic fields to automatically identify the electronically stored information in your smart ring. And meanwhile, the smart ring accessory collects energy from the RFID reader's interrogating radio waves. Comparing to Tesla key fob and any other key fobs, there is no charge and battery needed for your smart ring.
Your smart key ring is the perfect replacement for your original Tesla Model 3 key cards. So you won’t need to buy additional key cards, key card covers, and key fobs. It’s also a great way to save some space in your pocket, your handbag, or your purse.
