What is OPZ-NFC?

OPZ-NFC is a new, easy way to keep your crypto keys offline while still being able to access your crypto assets with a simple tap. It uses Near Field Communication (NFC) technology to store your encrypted keys offline.

Key Features of OPZ-NFC

  1. Offline Key Storage: OPZ-NFC allows users to store their cryptographic keys on any NFC device. By storing keys offline and using encryption, OPZ-NFC significantly lowers the risk of online threats such as hacking.

  2. Tap-to-Access Functionality: For transactions or accessing web3 applications, users can simply tap their NFC device against their phone. This feature brings ease and speed to the process, making it user-friendly.

  3. Encrypted Key Protection: The cryptographic keys stored on the NFC device are encrypted, ensuring high-level security. The encryption safeguards the keys, rendering them unusable if the NFC device is misplaced or stolen.

  4. Integration with OPZ Account Security: The NFC device works with the user’s OPZ account, which is secured by a password and multi-factor authentication. This dual-layer security ensures that the keys are not only stored safely but also accessed securely.

Conclusion

The OPZ-NFC Card enables users to store their MPC keys securely and interact with the OPZ Wallet and Web3 browser with just a simple tap. By providing a tangible way to interact with digital assets, it brings a new dimension to the crypto experience.

Devices:

OPZ-NFC is adaptable, working with a wide range of devices:
