Smart Ring
Smart rings like the Oura Ring are allowed in carry-on and checked bags, and you can wear one through security.

Carry-on details
Allowed. You can wear a smart ring through the security checkpoint like ordinary jewelry — it won't trigger extra screening on its own, though a metal detector alarm could prompt an officer to take a closer look.
Checked-bag details
Allowed. A smart ring's battery is tiny compared to a smartwatch or phone, well under lithium-battery limits for checked bags. Carrying it with you (worn or in carry-on) is still smarter than checking it, since it's small and easy to lose in luggage.
Special instructions
TSA has no rule written specifically for smart rings, so officers apply general wearable-electronics guidance — mentioning it before screening if it sets off an alarm can speed things along.

FAQ
- Do I need to remove my smart ring at airport security?
- No, you can typically wear it through the checkpoint just like a regular ring. TSA officers may ask you to remove it only if it triggers additional screening.
- Is a smart ring's battery too small to cause problems in checked luggage?
- Yes. Smart rings use a very small lithium battery, well within the limits allowed in checked bags, though wearing it or packing it in your carry-on is still the safer choice.
