The combination of these two Secure Elements allows COLDCARD to securely store the most critical piece of information in your Bitcoin wallet: the 24-word seed phrase. This seed phrase serves as the master key to your BIP39 wallet, granting access to your funds.

By storing the seed phrase within these Secure Elements, COLDCARD ensures that your Bitcoin is protected from unauthorized access. Even if the device is physically compromised, the seed phrase remains inaccessible without the proper authentication.
