Scramble Keypad (optional)

This feature helps protect from cameras and other observers by randomizing the numbers for entering the PIN on the display.

Steps:

  1. Go to Settings

  2. Select Scramble Keypad

  3. Press OK

Your keypad will now be scrambled!

Disable USB (optional)

This is to operate your device in a complete airgapped manner in case you do not have a power-only USB cable, since the data communication from the Coldcard will be deactivated as soon as this function is enabled.

Steps:

  1. Go to Settings

  2. Select Disable USB

Idle Timeout (optional)

Once activated, this feature will turn off the Coldcard after a predefined amount of time has elapsed.

You can set it to different values between two minutes and eight hours, or disable the idle auto-logout function completely.

Steps:

  1. Go to Settings

  2. Select Idle Timeout

  3. Select time

    • Default timeout period is 4 hours
