1. A Radio Frequency IDentification (RFID) extension for a mobile computer lacking RFID functionality, comprising:
- a standard modular attachment suitable for holding the mobile computer;
a battery carried by said standard modular attachment;
circuitry carried by said standard modular attachment and coupled to said battery for providing the RFID functionality, said circuitry including an electromagnetic transceiver and a RFID air interface decoder; and
modular attachment interface connected to said standard modular attachment for selectively coupling the mobile computer to said circuitry such that the mobile computer has access to the RFID functionality provided by said circuitry when the mobile computer is coupled to said modular attachment interface and is being held by said standard modular attachment, wherein said battery and said circuitry are separate from the mobile computer when the mobile computer is not being held by the standard modular attachment.

Abstract
A mobile computer and a reader are provided 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.
