This document provides an overview of RFID technology including key components like tags, readers, and antennas. It discusses different tag types based on factors like memory size, frequency range, and read/write capabilities. Regulations and standards related to various RFID frequencies are also summarized. Example applications are outlined for cases like conveying, handheld use, and intelligent labels. Major initiatives requiring RFID from organizations like Walmart and the Department of Defense are also mentioned.

What have I assembled or disassembled? How many do I have? Do I have enough? Has this been repaired? Is this under warrantee? Has this been inspected? Is this complete? What is the asset’s status or state? Wireless / Batch Inventory Management Material Handling By Destination Material Handling Aggregate / De-aggregate
