In one embodiment, a method of providing security operations in a secured facility in which access control operations are performed, wherein the secured facility includes a plurality of access control units physically distributed at different physical locations within the secured facility, comprises: performing access control decisions for the user of the at least one card according to the first data and the second data, wherein (i) the access control decisions determine whether a dynamic event variable set to a value determined by the second data satisfies a constraint defined by the first data or whether temporary tolerance data permits deviation from an applicable access control parameterized rule, and (ii) the access control decisions are performed in a de-centralized manner substantially where the access cards are presented to access control units without requiring access control logic being involved at a central access control system. |
