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.

Compatibility
- Compatible single-signature cryptograms.
- Multisignature cryptograms where EVERY configured signer is required for decryption.
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
- If only some signers are required—for example, X of 6 with X below 6—you need Cuvex 8K cards. This NTAG216 pack does not include them.
- These are not 8K cards. They cannot hold a cryptogram whose size or structure requires Cuvex 8K storage.
- 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.
