NAYAR guarantees the correct functioning of the ring for one year from the date of purchase, in accordance with our general terms and conditions of sale. The guarantee covers manufacturing defects, whether aesthetic or functional. Any damage caused by improper wear and tear, breakage or misuse of the ring is not covered by our guarantee.

All payment methods require an expiry date to comply with current security standards.

From the date of purchase of your NAYAR ring, you have 6 months to connect it to your bank. After these 6 months, it is likely that the connection will work perfectly, but we annot guarantee this. After connection, the product has an expiry date of 3 years. This date is not linked to that of the associated bank card.

When your bank card expires, the details of the new card issued by your bank will be automatically updated in your ring. So you won't need to change your ring or reconnect your card to it.

Your payment ring, like your bank card, does not need to be reloaded and is activated when close to a contactless payment terminal (between 1 and 2cm).

Your payment ring is a battery-free device. All the energy it needs to make payments is recovered during the payment itself.

NAYAR ceramic rings are waterproof and
dustproof. They have an IP68 protection class. They can be used, for example, at a depth of 5 metres in freshwater or in altwater under normal swimming conditions.

NAYAR ceramic rings are resistant to everyday knocks and scratches, but are still a piece of jewellery. It is therefore essential to take care of them to ensure their longevity and the quality of their visual appeal.

NAYAR rings are completely inactive when not in use. Like traditional payment cards (VISA or Mastercard), they do not emit waves when not in use, unlike battery-powered payment devices such as smartphones or connected watches or rings, which remain constantly active.
