Card startup & SELECT applet

When the card is powered, it first transmits an Answer to Reset (ATR) to indicate readiness for communication. The host system then selects the Cryptnox Wallet Applet using the SELECT command with the application identifier (AID = A0000010000112).

Upon successful selection, the card returns a status response containing:

• Applet type and version information
• Initialization and configuration flags (e.g., whether the card is seeded, PIN enabled, or initialized)
• User key presence indicators
• Custom bytes for manufacturer or firmware data

This stage ensures that the host application communicates with the correct applet and retrieves basic operational parameters before any secure transaction takes place.
