## Package com.alien.enterpriseRFID.reader Description

The Reader classes are the primary classes for communicating with a reader either over the network or serial port.

Typically the Reader object will be obtained from a Discovery Item object, discussed in the last section. However if the location (either serial port name or network address) is known, a Reader object can be instantiated directly without the need of any discovery classes. Once a valid reader object is available, it offers the user a number of simple commands that implement the full command set described by the Reader Interface Guide.
