Abstract
A first code is read from a user carried device useable in an access control system. The first code is an encoded form of at least an ID of a user carrying the device and at least one privilege. The privilege defines the user's access to a resource. The first code is compared to a second code, and access is permitted only if the first code compares favorably to the second code. A reader of the access control system computes the second code based on the user ID and the privilege. The first and second codes may be also based on a secret key applicable only to the user.
