Your Astari wearable can be set up in just a few steps using your smartphone. During setup, you connect your payment card and activate the wearable.

Astari wearables use passive NFC technology. This means they contain no battery, Bluetooth, or wireless connection and only activate when held near a payment terminal.

Once set up, your wearable works independently for contactless payments.

The best way to find your size is to use our ring sizer before ordering your final payment ring.

This helps you test the fit properly and avoid choosing a size that is too tight or too loose.

If you are between two sizes, we usually recommend choosing the larger size that feels most comfortable for daily wear.

Your ring should feel secure, but not too tight. Finger size can change slightly during the day due to temperature, movement, and water retention.

NFC, or Near Field Communication, is a secure contactless technology that works only at very short range.

Astari wearables use passive NFC chips, which means they do not contain a battery and do not send signals on their own. They activate only when placed near a contactless payment terminal.

This makes payments fast, simple, and secure.

Learn more here on our blog.

Most modern Android and iPhone devices with NFC support are compatible for setup.

You only need your phone during the initial setup. After that, your wearable works independently and does not require your phone to make payments.

If you are unsure whether your phone supports NFC, check your device settings or manufacturer specifications.

Setup guide here.

You can connect your Astari wearable directly to supported banks listed on our supported banks page.

If your bank is not listed, you can usually connect using the free Curve app, which supports most EEA Visa and Mastercard debit and credit cards.

No. Astari wearables never need charging.

They use passive NFC technology and contain no battery. The wearable is powered by the payment terminal during a transaction, so it is always ready to use.

Your wearable works even if your phone is not nearby or has no battery.

No. The wearable itself does not expire.

The payment token connected to your wearable may expire after around 3 years, depending on your card provider. When this happens, simply reconnect your card in the app to generate a new token at no extra cost.

This process can be repeated whenever needed.

Yes. All Astari wearables are waterproof and designed for everyday use.

You can wear them while washing your hands, showering, swimming, or exercising. Since they contain no battery or charging components, water does not affect normal use.

For long term durability, we recommend avoiding extreme conditions such as prolonged sauna use or deep diving.

Yes. You can connect multiple Astari wearables to your account and even use the same payment card on more than one wearable.

Each wearable has its own payment token and can be managed individually in the app. This allows you to rename, remove, or temporarily lock a specific wearable without affecting the others.

Yes, in many locations you can use your Astari wearable on public transport where contactless card payments are accepted.

Availability depends on the local transport provider and payment terminal.

A payment ring is simpler than a smartwatch because it has no battery, screen, notifications, or charging routine.

Once it is set up, it is always ready for quick contactless payments, even when your phone or smartwatch is not with you.

Paying with your Astari wearable works just like using a contactless card.

Hold your wearable close to the payment terminal until you hear a beep or see confirmation. The payment is automatically charged to your linked card or account.

If you use Curve, you can also switch cards before or after payment using the Curve app.

Learn more in our guide on how to pay with passive payment wearables.

Your Astari wearable follows the same contactless limits and PIN rules as a regular payment card.

You may be asked to enter a PIN in the following situations:

• If a payment exceeds your contactless limit
• After multiple contactless payments in a row, depending on your bank’s security settings

The PIN depends on how your wearable is connected:

• Direct bank connection: use your normal card PIN
• Curve connection: use your Curve PIN, available in the Curve app

No. Once setup is complete, your wearable works independently.

You do not need your phone, internet connection, or app to make payments. Simply hold the wearable near a contactless terminal and enter your PIN if required.

Learn more in our guide on how to pay with passive payment wearables.

You can use your Astari wearable anywhere contactless payments are accepted.

This includes most shops, restaurants, supermarkets, and many public transport systems worldwide.

You can also temporarily block or remove your wearable at any time using the app.

Learn more about contactless payment security.

Yes. If your wearable is lost or misplaced, you can block it immediately through the Manage Mii app.

If your wearable is lost, we recommend blocking it immediately through the app.

Yes. Astari wearables are completely safe to wear.

They use passive NFC technology and do not continuously emit signals or require a battery. The NFC chip only activates briefly when placed near a payment terminal during a transaction.

Curve is a digital wallet that lets you connect multiple payment cards to one account and use them through your Astari wearable.

You only need Curve if your bank is not directly supported by Astari. You can check compatible banks on our supported banks page.

Curve also offers useful features such as switching cards, spending notifications, and moving payments to another card after purchase.

Learn more in our guide on using Curve with Astari wearables.

Download the Curve app, create an account, and add your debit or credit cards.

Curve also offers Smart Rules to automate which card is used for certain purchases.

Learn more in our guide on using Curve with Astari wearables.

No. A virtual Curve card is enough to use your Astari wearable.

You do not need to order or activate a physical Curve card unless you want one for separate use.

No. Samsung Pay virtual cards issued by Curve are currently not compatible with Astari wearables due to tokenization restrictions.

If Curve automatically issued you a Samsung Pay card, you may need to reset your Curve account to receive a compatible standard card.
