Registering & Replacing

First registration

Registering names the card to your shell. From that moment, the card is yours — one active Card at a time.

Replacing a card

To replace a Card, you start a 24-hour pause:

• The new Card is registered but not yet usable
• The old Card stays alive for the day
• At the end of the day, the new Card takes over

The pause is the safety net — so a card you may still be carrying does not stop working in the middle of the day. The old Card keeps you company until the new one is ready, and then quietly retires.

Your own card's settings

Tap your own Card to your phone and it opens the Card's settings. You can rename it, change the daily limit, freeze it, mark it lost, or begin replacing it with a new one.
