$CFX The most revolutionary aspect of the SIM card is that it lowers the threshold for Web3 to 'zero technical requirements'.

No need to install an additional wallet app; the mobile phone directly binds to the on-chain identity (DID), equivalent to having a 'real-name digital ID', simplifying the entire process of managing virtual assets and logging into compliant platforms, making it operable even for those who do not understand professional terminology.

Completely free from the constraints of mnemonic phrases, the private key is generated and permanently stored by a secure chip within the card. 'The private key never leaves the card'; even if the phone is rooted or infected with malware, assets will not be stolen. It also supports biometric recognition and SMS verification for key recovery, eliminating the tragedy of 'losing the mnemonic phrase = losing the assets'.
