Keys, cards and phone can stay in your pocket. The R3 is a compact metal NFC ring that opens compatible doors, connects to your phone. Set it up once, test one reader, and the tap becomes the habit.
A smart ring that opens doors and connects to your phone with a single tap
- carrying cards or keys
- fumbling for phone or wallet
- unlocking access doors quickly
Doors and phone, one tap away.
Before: digging for keys, cards and your phone at every door. After: a compact metal NFC ring that opens doors and connects to your phone where your setup supports it.
One ring that replaces the keys in your hand
One tap to open doors
The built-in NFC chip works with compatible readers, so one tap replaces the keys and badge you would otherwise dig for. Hold the ring still at the reader for a moment and the read registers. Access points that support NFC are where the ring earns its keep.
Metal ring with a polished finish
The gloss black outer shell sits over a polished silver inner band. It reads as jewelry on the hand, not as tech gear.
Connects to your phone
One tap connects the ring to a compatible NFC phone, which skips the unlock and search routine. How quickly this works depends on your phone model and the apps you have enabled.
Set it once, then tap through your day
- 1Check your phone and doors
Confirm your phone supports NFC and that the door or turnstile you use is an NFC reader. Without a compatible reader, the tap will not register.
- 2Test one door first
Hold the ring steady near the reader for a moment. A clean read confirms the setup works before you rely on it at the office or the station.
- 3Tap at the commute gate
Keep the ring on your access hand. Hold it near the gate reader until it registers, then walk through without reaching into your bag.
- 4Tap it to your phone
On an NFC-capable phone, hold the ring to the back of the phone to trigger the action you set up, such as a contact card, a link or a shortcut. What it can trigger depends on your phone and apps.
From a bag search to one tap
The morning scramble
Keys in one pocket, a badge on a lanyard, the phone somewhere at the bottom of the bag. The door waits while you search. Every lost card or fob turns a five-second entry into a locked-out morning.
One tap, nothing else
The R3 carries an NFC chip in a metal ring. You hold it to the reader, the lock releases, and you keep walking. Phone and wallet stay where they are. The ring does one job and does it at the point where you need it.
Check it fits your day
Before you rely on it, check that your phone and your doors speak NFC. Test one reader, confirm the read is steady, then wear it for a week. Most people decide within a few commutes whether the ring has earned its spot on the hand.
What to expect over the first month
- First useConfirm your setup works
Test the ring at one door or with your phone first. A successful tap tells you the setup is ready before you rely on it at work or at your door.
- Week 1Stop reaching for the bag
You may notice you stop digging for keys or a badge at their usual doors. Results depend on your readers and phone.
- 30 daysDecide if it earns its place
After a month of commutes and office taps, you can judge whether the ring replaces your key or card and fits comfortably all day.

Questions and answers
It works with NFC readers and NFC-capable phones. Your phone, your door system and how your access is set up decide whether a given door responds. Test one reader before you rely on the ring every morning.
The ring only opens what your own system has enrolled. Access control is set on the reader and account side, so a stranger cannot open a door just by owning the ring. Keep the ring on your hand, and treat it like any other access credential if you lose it.
The ring comes in sizes 7 through 12. Measure your finger at the end of the day, when it is at its largest, and pick the size that slides on with a little give. A snug fit is normal the first day, and it usually eases after a few days of wear.
No. The R3 is an NFC access and connection ring. It does not track steps, heart rate or sleep. If you want health tracking on your hand, look at a fitness ring instead.
No. The R3 is a passive NFC tag, not a payment device: it holds no bank card and cannot pay at store terminals. Tap payments stay on your phone or bank card.
It replaces the search, not the credential: the ring stays on your hand, so there is nothing to find in a bag at the door. Whether that is worth it depends on how many doors you tap through each day. Test one reader first.
