Deciding cardholder access within your facility is perhaps the most important security measure you can implement. Access level groups make this process much easier, but you might encounter difficulties when one user needs approval from a card reader that would normally deny the rest of the group, or vice versa. Precision access, a special kind of software that allows administrators to choose individual readers to grant or deny access to specific badges separate from access level assignments, alleviates this issue.
The process works by adding badge numbers to a special precision access database. Although the user would usually be denied access, you have noted that their unique badge number should grant them access, so they are allowed to continue. This works best if you use it most for a few employees — more than that and it’s more advantageous to just create a new access level for that group of cardholders.
