What is a Blacklist?

A list of cards that are denied for authentication on the BioStar device. When a card is lost or stolen, misuse can be prevented by registering the ID of the card in the blacklist.



Why would you want to delete a blacklisted CSN card?

In BioStar 2, if you

  • Block (blacklist) a CSN card and then delete card
  • Block (blacklist) a CSN card and then delete the user

In such cases, you cannot reuse this card because the card remains in the Blacklist and there is no way to delete it from the list. 


The best way to prevent such problems is to delete the user after unblocking the card so please keep that in mind.


In a future version of BioStar 2 you will be able to delete such Blacklisted cards within the UI, but for now, you can use the temporary solution below to delete the Blacklisted card. 

Note: This solution only applies for CSN cards.



BioStar 2.3~2.5


Note: the information below is for Maria DB type which is the default database of BioStar 2. 


If you would like to run the query on a database management program manually, you can run the query below. 


start transaction;
USE biostar2_ac;
DELETE 
FROM T_BLKL 
WHERE CRDUID = (SELECT CRDUID
FROM T_CRD
WHERE CRDCSN='134149339' ) ;
UPDATE T_LSTSYNSTA SET BLKL = 0;
COMMIT;


Enter your card number in '134149339' and run the query.  


If you would like to run a script without installing a database management program, you can use the attached .bat file. 

Change the file extension to .bat and run it with administrator privileges on the PC with the database.
