Frequently Asked Questions
Q: Does the NFC Smart Ring require charging?
A: The passive NFC chip used for door access control requires no battery or charging — it draws power from the reader when tapped. Wellness-tracking sensors that record heart rate, SpO₂, sleep, and other body signals do use onboard power; refer to the SmartLife app for battery status and charging instructions specific to your model.
Q: Is the SR01-NFC Smart Ring compatible with all NFC access-control systems?
A: The ring is compatible with most standard NFC-based access-control systems, including building door readers, elevator panels, and parking lot barriers. We recommend confirming with your building manager that your system supports standard NFC (13.56 MHz) cards before ordering.
Q: Can I wear the ceramic NFC Smart Ring while swimming?
A: Yes! The ring carries an IP68 waterproof rating and is tested to withstand submersion up to 50 meters, making it suitable for daily hand-washing, rain, pool swimming, and snorkeling. Avoid prolonged exposure to high-pressure water jets or hot springs above rated limits.
Q: How do I choose the right ring size?
A: Wrap a thin, non-elastic thread around the base of the finger you'd like to wear the ring on. Mark where the ends meet, lay the thread flat, and measure the length in millimeters. Match that measurement to the inner diameter column in the sizing table above (sizes US #7–#12, from 17.2 mm to 21.5 mm) to find your ideal fit.
Q: Which smartphone app does the smart ring use?
A: The LUCKING DOOR SR01-NFC pairs with the SmartLife app, available for both iOS and Android. The app displays your wellness trends, sleep reports, activity history, and allows you to configure remote camera and video controls.
