I noticed a problem with this design:
If you need to delete a card, you need to input the system card first, then the card to be deleted.
If you need to delete a card that has been stolen/lost, there is no way to do it with this system.
On my honour I promise that I will do my best—
To do my duty to God and the King (or to God and my Country)
To help other people at all times and
To obey the Scout Law.
