NFC offline backup mechanism
This system uses NFC sensing technology to write and read mnemonic phrases, requiring no network connection or power supply. The data interaction process is physically isolated, reducing the risk of remote attacks and malware theft, making it suitable for long-term offline storage scenarios.
Long-term stable storage structure
The card is encapsulated in weather-resistant materials, contains no electronic batteries or active components, and is unaffected by system versions or device updates. It is waterproof, dustproof, and heat-resistant, making it suitable for long-term storage of mnemonic phrase information.
Standardized mnemonic compatibility
Supports mainstream BIP39 mnemonic phrase standards and is compatible with common hardware and software wallet recovery processes. The clear information structure reduces human error during recording and recovery, ensuring data readability and consistency.
