Abstract
The system and method for automatically controlling or configuring, a device, such as an RFID Reader, reads a master control tag to upload sets of instructions from the tag to memory resident in the reader. Thereafter, the reader may read a control tag to select one or more sets of instructions stored in memory. The reader may thus be readily programmed without the need for physically connecting the reader to a computer, and without employing expensive key pads and display screens.
