Wal-Mart S.M.A.R.T System

I live close to a walmart in Burtonsville MD, so I decided to write this Paper on their Inventory System. Wal-mart, the wholesale retail monopoly, focused on developing an RFID-based electronic product code, or EPC. The electronic code would allow businesses to track shipments and inventory automatically through a system of tags and sensors. It was a potential replacement for the manual scanning of bar codes, a technology that itself revolutionized retail two decades earlier.

The most interaction with the SMART system is through the Telxon. The Telxon is a 900 MHz wireless handheld terminal equipped with a barcode scanner. When a barcode is scanned, almost instantly the item number, description of the product and amount on order are displayed. The technicalities of this system are a bit too complicated for me but I can only assume that the Telxon is linking to the SMART database to retrieve all of products in the stock database information. All from a simple thing like a barcode which is just a set of numbers that are unique, like a primary key. 

A brief history of the Telxon, The Telxon handheld unit, first deployed five years ago, is Wal-Mart's Swiss army knife. Equipped with a keypad, bar-code scanner, a 16-line character display, and radio...
