RFID Access · 125 kHz · T5577
Replace the keycard. Wear the key.
A discreet, scratch-proof ring that opens your apartment, gym, mailroom, and parking garage. No card. No fob. No phone.
Effortless
Tap to unlock. Your hand is always with you — your wallet isn't.
Universal
T5577 emulates HID Prox, EM4100, and Indala — the chips already in your building.
Affordable
From $39. Less than a replacement card after your second lost set.
Built to last
Ceramic, titanium, tungsten. Waterproof. Scratch-resistant. No battery — ever.
The collection
Six finishes. One technology.
Every ring carries a T5577 chip. Pick your style. We'll handle the size and the programming.
How it works
Three taps from card to ring.
1. Pick a ring
Choose a style and size. We carry US 6 through 13 in every finish, in stock.
2. Send us your credential
Mail your fob in our prepaid envelope, swing by our Charlotte studio in person, or — if you’re a Flipper / Proxmark user — email us the dump. Three ways.
3. Wear and tap
Locked or re-programmable. Either way, it works the moment it's on your hand.
Why a ring
Quiet luxury, with a job to do.
A keycard is something you misplace. A fob is something you fumble. A ring is on you the moment your hand is. Access Rings was built around one idea: the most useful access device is the one you don't think about. Our rings are programmed before they ship, sealed with epoxy, water-rated to IP68, and finished in materials we'd be happy to wear ourselves. There is no app. There is no battery. There is just you, and the door, and a small piece of jewelry that knows the difference.
