The Vault Key Card
Cold wallet security without the usual complexity.
The Zypto Vault Key Card gives you the protection you expect from a hardware wallet, with none of the hassle that usually comes with it. No setup rituals. No extra devices to manage.
Pair it once, and your wallet requires a physical tap to approve any transaction. Your assets stay on chain. Your approval stays in your hands.
With NFC tap authorisation, multi wallet support, and optional biometric confirmation through Zypto App, you get a clean, controlled way to manage your crypto wherever you are.

Tap to Authorise: A simple NFC tap brings your wallet online for one action only. Nothing more.
Built for Mobile: Designed specifically for Zypto App, turning everyday wallets into cold-authorised wallets in seconds.
Up to 3 Wallets Per Card: Secure multiple wallets with one card. Expand anytime with additional cards.

Built to be carried. Built to last.

NFC Shielding Sleeve: Each card includes a matte black protective sleeve that blocks unwanted NFC interaction, keeping your card inactive until you need it.
Complete Set: Every Vault Key Card comes presented in a protective box with its shielding sleeve, ready to use or store securely.
Shipping available internationally.

Full control. Every time.
Tap Required: No transaction can be approved without your Vault Key Card present.
One Action, Then Offline Again: Tap to authorise, complete your transaction, and your wallet returns to its offline state.
Biometric Layer: Add optional device-level biometrics to unlock your app before preparing a transaction. Final approval still requires your Vault Key Card.
This is control you can feel. Simple, direct, and hard to bypass.
