A system of tracking objects through a service process at a service shop comprises a computer network configured to track movement of tagged service objects from physical location to physical location within the service shop. The computer network comprises tag readers with antennae configured to receive transmissions from tags encoded with identifiers and connected to associated tagged service objects. The tag readers transmit identifiers obtained from the tag transmissions together with an indication as to which antenna received each transmission. Servers receive the identifiers transmitted from the tag readers and determine, based at least on the identifiers and which tag reader antenna received the transmissions, which physical location each service object associated with the received identifiers occupies. Client workstations generate a visual map of physical locations together with summary status information showing which service objects occupy the displayed physical locations.
