Frequently Asked Questions
🔐 Is it safe to use an Astari wearable?
Yes! Astari wearables are Mastercard-certified, ensuring the highest international security standards. Payments work like a contactless debit card, and if needed, you can temporarily block your wearable anytime via the Manage Mii app.
🔋 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.
💳 How do I choose the right payment card when linking multiple cards?
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).
⚡ How long does setup take?
Setting up your wearable is quick and takes just a few minutes. Need help? Follow our detailed setup guide.
💦 Are Astari wearables water-resistant?
Yes! Our wearables are water-resistant and won’t be damaged by water. However, if you have a leather wearable, we recommend keeping it dry to maintain its quality and longevity.
🛡️ What is my warranty?
All Astari wearables undergo rigorous testing and come with a minimum 2-year warranty from the date of purchase.
