Wearable Crypto Wallet Ring Size 13

The Tangem Ring Size 13 is a ceramic hardware wallet worn on the finger for secure self-custody of digital assets. It generates and stores private keys inside an EAL6+ certified secure element that never exposes them. The ring operates completely offline with no battery, cables or charging required. Two backup cards are included to clone the key during setup for recovery.

Sustained Use Behaviour

The ring draws passive power from an NFC-enabled smartphone each time a transaction is signed, so there is no internal battery to degrade over time. Firmware is non-upgradable, removing the risk of remote software changes during long-term ownership. The zirconia ceramic shell resists scratches and maintains its finish through daily wear. Keys remain isolated in the secure chip regardless of how often the ring is tapped.

Thermals Noise and Power

No active components mean the ring produces zero heat and no audible noise during operation. Power is harvested only from the phone's NFC field at the moment of signing, placing no continuous draw on the mobile device. The ceramic body stays at ambient temperature even with repeated taps. There are no fans, coils or moving parts to create vibration or electromagnetic noise.

Questions about this item

Does the ring generate any heat or need charging when I wear it all day?

The ring has no battery and draws passive power from your phone via NFC, so it produces no heat and never requires charging.

What phone or app do I already need so the ring can sign transactions?

You need an NFC-enabled iOS or Android smartphone with the Tangem mobile application installed.

Will the Size 13 ring and its two backup cards work together if I also keep an older Tangem card wallet?

The ring and its two included backup cards form a self-contained backup set; they do not interact with any other Tangem cards you may own.
