Block certain card numbers via a blacklist or whitelist

To block certain card numbers, you can add a blacklist or whitelist to your reader configuration. The reader then blocks the respective cards autonomously, so you don't have to make any changes to the host system.

This feature is available in BALTECH ToolSuite as of version 4.21.00.

Blacklist or whitelist?

  • In a blacklist, you specify the card numbers you want to block. All other numbers are allowed.
  • In a whitelist, you specify the card numbers you want to allow. All other numbers are blocked.

Don't mix the 2 approaches. Otherwise, you may end up with unwanted results.

  4. In the List Type dropdown, keep Blacklist selected.

  5. In the Card Number Length field, specify how many digits your card numbers consist of.
    This is the length as defined by your project settings.
  6. In the Block All Numbers Smaller Than field, enter the first number in the range of your project numbers.
    In the Block All Numbers Larger Than field, enter the last number in the range of your project numbers. Thus, all numbers outside this range are automatically blocked.
  7. To additionally block an individual number within the range of your project numbers, click Green Plus icon at the bottom of the input box and enter the number.
  8. To remove an individual number from the blacklist, click the relevant entry, then click Red delete icon at the bottom of the input box.
