Once you receive your wearable, you can connect your bank via the mobile app within five minutes. All you have to do is tap the wearable on the back of the mobile phone, add your bank account and you are free to make contactless payments, it's that simple.

NFC (Near Field Communication) allows you to exchange contactless data safely and quickly. NFC is comparable to Bluetooth, but the range is less. Thanks to NFC, you can pay contactless or easily share your contact details. Good to know is that Astari products have passive NFC chips, so they do not emit radiation and can only be read.

The payment works in the same way as contactless payment with your payment card. Hold your wearable close to the payment terminal to make contactless payments. These payments are debited from your account linked to the wearable, just like payments with the debit card.

Yes, the chips we use are fully certified (EAL 6+, EMVCo, Visa, Mastercard, etc.), support NFC (ISO 14443), ISO 7816, I2C and are compatible with Mifare.

If your wearable is lost or stolen, you can (temporarily) block it via the mobile app.

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 quickly be blocked via the app and possibly reordered.

Wearing the wearable/chip does not generate radiation or vibrations that can affect your body. This is because Astari wearables use passive NFC technology, unlike smartwatches, wireless earphones and phones.

Active NFC readers such as payment terminals and telephones read the passive transponders (the Astari wearables). The Astari wearables do not generate a return signal themselves and therefore do not pose a risk to your health.

There is an active NFC chip in an ATM. This chip can communicate with other NFC chips, such as the ones in your phone or wearable. The NFC tag in the ATM transmits a certain task via radio waves. You can then pick up these waves with the antenna of the NFC tag in your wearable. Certain tasks can be sent along with these radio waves. The task is captured and can be executed immediately. The radio waves can bridge a maximum of 10 centimeters. Thanks to the limited distance, the technology is very suitable for payments and sharing your contact information.

When we add new functionalities to the wearables, you do not have to buy a new one again. As soon as we have implemented this, it will be available in the app, so you can simply update your current Astari wearable with the latest functionalities. Do you want to stay informed of developments? Then follow us on one of our socials or sign up at the bottom of the page for our emails. Don't worry, we don't send you a newsletter every week.

Wherever you can now pay contactless, you can now pay with the wearable.

To enable the payment functionality, a secure digital copy of your payment card – 'token' – is made and placed on your wearable. This is also completely safe and is supported by the payment providers to guarantee this.

The wearable is compatible with any smartphone that has NFC functionality. All functions are performed via the telephone application, but you set this up once, after which the telephone is no longer needed.
