Abstract
Described is a mobile computer and a reader that may be constructed as a standard modular attachment (e.g. sled) for the computer that may be used only when RFID interrogation is desired. The sled may carry an antenna loop, integrated RFID reader electronics, and a dedicated battery that are separate from the actual mobile computer.
