How does a payment ring work?
The Technology Behind the Tap to pay Ring
A payment ring may look like a sleek, minimalist accessory—but under the surface, it’s a powerful piece of wearable payment technology. Using the same NFC (Near Field Communication) system found in contactless cards and mobile wallets, this smart ring lets you pay securely with just a flick of your hand.
But how exactly does this ring turn from jewelry into a secure payment tool? Let’s break it down.
🔁 1. The Embedded NFC Chip
At the core of every payment ring is a passive NFC chip. “Passive” means it doesn’t require a battery, Bluetooth, or charging cable to operate. Instead, it’s powered wirelessly when brought near a contactless payment terminal.
Once activated, the chip transmits encrypted payment information to the terminal, enabling a secure, wireless transaction—no cords, no complications.
🔐 2. Tokenization: Secure by Design
Unlike old-school magnetic cards or wearables that store real card data, payment rings rely on tokenization.
When you set up your ring through a compatible digital wallet (like Bybit or Curve) or a supported bank, your actual card number is never stored on the ring. Instead, the system creates a unique encrypted token, tied exclusively to:
-
Your card
-
Your ring
-
Your payment provider
This means even if someone were to somehow intercept the data, it’s useless without your ring and account.
🔄 Tokens typically expire every 3 years as part of standard security protocols. When that happens, there’s no need to replace your ring — you can simply re-tokenize it using the app or digital wallet to continue using it seamlessly.
Unlike traditional bank cards, your ring doesn’t become obsolete when the token expires. There’s no forced replacement — just a quick refresh, keeping your wearable secure and future-ready.
🧾 3. Making a Payment: Simple, Fast, Intuitive
Paying with your ring couldn’t be easier:
-
Form a relaxed fist.
-
Hold the ring parallel and close to the terminal.
-
Wait for the beep or confirmation screen.
-
Done.
It works just like a contactless card — only more discreet, durable, and always on hand.
For larger purchases, PIN confirmation may be required, just like with a regular contactless card. This keeps your payments both fast and secure.
🔋 4. No Charging, No Maintenance
Unlike smartwatches or phones, Astari payment rings require zero upkeep. There’s:
-
No Bluetooth
-
No charging
-
No syncing
-
No app needed after setup
The ring draws its energy directly from the payment terminal—meaning you can swim, shower, and go about your life without ever taking it off.
🛡️ 5. Built-in Security from Every Angle
With no magnetic stripe, no exposed data, and bank-grade encryption, payment rings offer a new standard in secure contactless payments. And for added peace of mind, rings paired with a companion app like Manage Mii can be instantly frozen or disabled remotely.
