The ring is fabulous! It works beautifully: exactly like you'd hope it would, and set-up was extremely simple. Delivery was fast and the level of customer service from Mike at Astari is what every company should aspire to. A brilliant experience from start to finish.

Just got an Astari ring for my birthday and I have to say it's one of the best presents ever. Easy to set up once you download and set up a curve account and the Manage-mii app. Started using it the next day. No problems. Get one now

Love my wearable wrist band…
Very handy to use so you don’t have to keep your card close..
Also, I had excellent customer service when I had a bit of a problem, which was sorted without question very quickly.
I recommend this.

I genuinely love this ring so much - I bought it as a 'Just-in-case I forget my phone' but to be honest I just use it instead because it's always there and I don't have to get anything out. Can definitely see this being a great gift for someone too. I also love the design.

I absolutely LOVE my new Astari ring! The service received has been excellent. So convenient to use and a gorgeous ring also. A couple of minor tech issues getting it set up but once done it has worked really well. Lots of surprised looks when I use it in the shops :)

Received my ring yesterday and found the connection process pretty easy .
Used the ring for the first time today and like anything new in the technology world you wonder is it going to work, and yes it worked without any issues, and so much more convenient that having to get my card out. So overall impressions are very positive and I am glad I purchased it.

If you follow the instructions it takes about 5 mins to set this up successfully and have it paired to a UK bank [Starling Bank in my case]. Comfortable to wear and easy to use it's not failed any transactions yet and I don't expect it too. Very Happy.

It was simple, the fact the option for getting a ring sizer if your unsure is great. Support is really simple and letting me know what the status of the particular size was e.g it was out of stock due to demand. But you gave me an ETA of when it should be back and sent. Class customer service and the set up was really straightforward. I would recommend to anyone.

How do I make payments?

Making a payment is as simple as using a contactless card. Hold your Astari wearable close to the NFC-enabled payment terminal until you hear a beep or see a confirmation message. The payment will be automatically deducted from the linked card or account.

Tip: If you have multiple cards linked via the Curve app, you can choose which card to use directly from the app—even after a payment is made. For best practices, see our guide on how to pay with passive payment wearables.

Is it safe to pay with?

Yes, all Astari wearables are certified by Mastercard and meet the highest international security standards for contactless payments.

Your payment credentials are stored in the form of a secure, encrypted token — similar to those used by mobile wallets like Apple Pay or Google Pay. No personal information (like your name or card number) is visible during a transaction, ensuring your privacy is always protected.

Astari wearables function just like a contactless debit card. They follow the same spending limits as the connected payment card — and for transactions above this limit, you’ll be prompted to enter your PIN. If needed, you can temporarily lock or disable your wearable at any time using the app.

This makes Astari wearables a safe, reliable, and private way to make payments — without needing your phone, wallet, or charger.

Do I need to charge the wearable?

No, Astari wearables use passive NFC technology, meaning they never need charging and are always ready to use—even if your phone runs out of battery.

Do I need my phone nearby to pay?

No, once set up, your wearable functions independently. Simply tap and pay—no phone required!

Does the wearable expire after 3-4 years like a payment card?

No, the wearable itself does not expire. However, the payment token linked to your card has a lifespan of about 3 years. When it expires, simply delete and reconnect your card in the app to extend usability—this process can be repeated indefinitely, free of charge.

Can I add multiple cards?

Yes, use the free Curve wallet app to link multiple Mastercard or Visa cards.

✔ Set a default card in Curve.

✔ Switch cards before paying or even reallocate payments afterward.

✔ Automate spending rules (e.g., groceries from Card A, purchases over €200 from Card B).

Is my wearable waterproof?

Yes, all Astari wearables are fully waterproof and designed for everyday life.

You can wear them while washing your hands, showering, swimming, or even in the rain without any problem. The internal NFC chip is sealed inside the wearable with no moving parts or battery, so there’s nothing to short-circuit or damage from water exposure.

That said, while they’re built to handle water, we still recommend avoiding high-pressure environments like diving or saunas for prolonged durability — just like you would with most jewelry.

Whether you’re heading to the gym, the pool, or just going about your day, your Astari wearable is ready to go wherever you are.

What is my warranty?

All Astari wearables undergo rigorous testing and come with a minimum 2-year warranty from the date of purchase.
