CSN Mobile Card Deletion Management Guidelines
When using CSN mobile cards integrated with the Airpop Portal Regular Site in BioStar 2, if a user deletes a card, the same card ID could be reissued to another user. However, this could lead to an issue where the original cardholder could still access the premises even after the card has been reissued.
To address this issue, the system has been improved to manage the history of deleted CSN mobile cards.
Separate Management of Deleted CSN Mobile Cards
Deleted CSN mobile cards are recorded in the Settings → Card → Deleted CSN Mobile Card list. In this list, you can view the Card Type, Card Data Format, Card ID, and Last Cardholder.

Preventing Reissuance of Deleted Card IDs
If there is a history of deletion for a CSN mobile card, the system will prevent that card ID from being reissued to another user.

To reissue a card with a deleted card ID, the corresponding CSN mobile card must first be removed from the Deleted CSN Mobile Card list.

CSN mobile cards included in the Deleted CSN Mobile Card list cannot be deleted from the Unassigned Card list.
To delete a card from the Unassigned Card list, first remove the card from the Deleted CSN Mobile Card list and then proceed with the deletion.
