Once you've received your wearable, you'll be able to pair your wearable via the mobile app. Read how to do this on our setup page.

With NFC (Near Field Communication) you can exchange data safely and quickly and contactlessly. NFC is similar to Bluetooth, but the range is shorter. Thanks to NFC, you can make contactless payments or easily share your contact details. It is good to know that Astari products have passive NFC chips, so they do not emit radiation and can only be read.

Payment works in the same way as contactless payment with your regular payment cards. Hold your wearable close to the payment terminal for contactless payment. These payments will be debited from your account linked to the wearable, just like payments with the debit card. Make sure to remember your PIN code.

Our wearables use the same NFC technology found in your bank cards, therefore you can be confident that your transactions are fast, secure, and reliable. Without showing your personal information on your card or phone to other people. 

If your wearable is lost or stolen, you can (temporarily) block it via your account that you have used to set the wearable up.

Because our wearables are passive, which provides an extra level of security against scammers, tracking is not possible. If the wearable is lost, it can be quickly blocked via the app/ your account and reordered.

No, wearing the wearable/chip does not generate any radiation or vibrations that can affect your body. This is because Astari wearables use passive NFC technology, unlike smartwatches, wireless earphones, and phones.

Wherever you can now make contactless payments, you can now pay with the wearable. When you link you payment card(s) with Curve it is even possible to pay with your credit card where this was not allowed previously. This works because you pay with your Curve card, that is linked to your other cards.

We have direct links with a number of EU banks that you can find here.

However for everyone that has a different bank, we work with our wallet partner Curve, to make wearables accessible for everyone with a Mastercard, Visa, Discover card or in the UK even Paypal as well. This allows you to connect multiple cards to the wearable and switch payments to a different card even after they have been made. You can find more on our setup page here.

The wearable is compatible with any smartphone that has NFC functionality, which include almost every modern smartphone. All functions are performed via the mobile application, but you only have to set it up once, after which the phone is no longer needed.

Because Astari uses analog technology, you never need to charge the wearable and are always ready to use it. Even if your phone's battery is dead.

No, you don't need a phone nearby to pay. After setting it up once, you can now make payments using just the wearable! (and PIN)

To link multiple cards, use the free wallet app Curve (see our setup page). You select a default card in the Curve app, and if you want to use a different card, you can select it before you pay, or you can transfer the payment to another account afterwards. You can set up rules in the Curve app to make sure your payments go to the right card without having to choose. For example, groceries from card A, and anything above 200 EUR from card B.

No, the wearable will still be usable after these years. The payment token you put on the wearable during the setup, has a lifespan of about 3 years. When this has expired you can just delete the token and connect your payment card again in the app, you will now have another 3-4 years of usability. The beauty is that you can do this yourself and can be done over and over without any additional charges.
