Ⅰ. Introduction
Ⅰ-1. Motive and Purpose
-Ubiquitous Trend of RFID (Radio Frequency Identification) can replace the barcode system. So it has emerged as a major area of ubiquitous and has been being utilized in many uses due to the high efficiency and several benefits. So our team wants to analyze and get a deep understanding about general RFID system through existed case studies.

Airport management, in common with others involved in the operation of elements of the civil air transportation system, are required to take measures that will provide a high level of protection of buildings and equipment (including aircraft), in addition to ensuring the safety and personal security of passengers and staff using the system. This must be done in manner that disturbs the normal ope
1.2 Structure of Planning for Security

A bipolar transistor has terminals labeled base, collector, and emitter. A small current at the base terminal, which is flowing through this way, can control or switch a much larger current between the collector and emitter terminals
And for a field-effect transistor, the terminals are labeled as gate, source,

to make greater use of these energy sources.
The first problem is that the fossil fuels are depleting in a rapid rate and are harder to retrieve. The consequence is that we can be facing an energy crisis in the future is we are not careful today. The energy prices will sky rocket and not be available for many individuals or countries. To avoid this doom scenario we need to find alternatives an
