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.
Raymond Edwards
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 :)

Great product, simple to set up. Highly reccomended.
Michael T.
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.

Excellent experience from ordering to setting up my wearable.
The support team was extra helpful when needed, the delivery was fast and the product looks and works as expected.
Keep it going!

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.
Andy Holt
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.

Description
Contactless Payment Keychain Achilles
Standing at a checkout with your hands full is usually the moment people realize how often they still rely on their wallet or phone. Whether you are grabbing coffee before work, paying for public transport, heading into the gym, or quickly stopping at a store while traveling, small payment moments happen constantly throughout the day. The Contactless Payment Keychain Achilles was designed to make those moments feel simpler, faster, and more natural without adding another device to manage.
The Achilles is a contactless payment keychain crafted from premium apple leather and built around passive NFC wearable technology. Unlike smartwatches or battery powered wearables, it never needs charging, software updates, or cables. Because the technology is passive, the payment keychain is powered directly by compatible contactless payment terminals during transactions. It simply stays attached to your keys and remains ready whenever you need it.
For many users, that convenience quickly becomes habit forming. Your keys are already part of your daily routine when leaving the house, driving, commuting, or locking up after the gym. Instead of remembering another device or checking battery percentages, payments become integrated into normal everyday movement. Many people notice that after a few weeks, reaching for a wallet starts feeling surprisingly unnecessary for smaller daily purchases.
The Contactless Payment Keychain Achilles is also an ideal introduction to wearable payments for users who prefer not to wear rings or smartwatches. There are no sizing concerns, no adjustment period, and no extra technology sitting on your wrist or finger. It offers the convenience of wearable payments in a familiar object people already carry every day.
The premium apple leather construction was selected not only for sustainability, but also for practical long term usability. The material feels lightweight, soft, and comfortable in hand while remaining durable enough for constant everyday carry inside pockets, bags, or attached to keys. Combined with its waterproof construction, the Achilles keychain is designed for real daily situations including commuting, travel, workouts, rain, beach days, and active use throughout the day.
The Achilles uses secure NFC payment technology similar to the contactless infrastructure already trusted worldwide by banks and payment networks. In many regions, the payment keychain can be connected through Curve, allowing users to securely link existing debit or credit cards while maintaining modern tokenization and contactless security standards.
A passive payment wearable does not require charging because it uses NFC technology powered directly by the payment terminal during transactions. This allows the keychain to remain lightweight, minimal, and continuously available without battery degradation over time.
If you are new to wearable payments, you can learn more about how to set up your Astari wearable and check compatibility on our supported banks page.
Many users also explore how to pay without a wallet or phone before choosing their wearable payment device.
For users looking for a simpler alternative to carrying cards, wallets, or battery powered wearables everywhere, the Contactless Payment Keychain Achilles offers a quieter and more practical payment experience. Lightweight, discreet, and always available, it fits naturally into everyday life without adding extra friction or complexity.
