Backups that fit your plan.
Store copies of your Cuvex cryptograms and distribute them according to your self-custody plan. The card holds data that is already encrypted: its NFC chip does not replace the device or decrypt data on its own.

NXP MIFARE DESFire EV1 8K chip · 8 KB nominal memory · NDEF Type 4 format for Cuvex · 13.56 MHz. Usable capacity depends on formatting and metadata.
NTAG216: 888 bytes. Cuvex 8K: 8 KB nominal memory. Choose 8K for cryptograms with a signer threshold, not because of the card color.
Compatibility
- Compatible single-signature cryptograms.
- Multisignature cryptograms where EVERY configured signer is required for decryption.
- Threshold multisignature cryptograms that require only some of the configured signers, including X-of-6 workflows supported by Cuvex.
Here, single-signature and multisignature describe the authorizations needed to DECRYPT a cryptogram, not the number of signatures on a Bitcoin transaction.
Limits to understand
- The extra capacity accommodates larger cryptogram structures. It does not, by itself, strengthen encryption or replace the required access authorizations.
- Biometric-protected Cuvex BIT cryptograms cannot be cloned onto passive NFC cards, whether NTAG216 or 8K. External backups require the supported USB-C storage workflow.
