A pigment with modified properties because of the powder size being below 100 nanometers. The system includes a printed surface having visible graphical information indicating a user selectable operation, and coded data. An edge area of the strip is configured to immediately re-capture coins as they are released at the exit area and to hold the coins until they pass by a segment of the strip that is far enough away from the indexing line of the coins that they are no longer captured, but are freely released. Once it is determined that the resource has become available, the predicted wait times of the queues are updated based on a prior contribution of the resource to the queues; a performance level of each of the queues relative to one or more service level targets; and the resource is assigned, in response to the determination, to the request based on the evaluation.
