Abstract:
RFID is an acronym for Radio Frequency Identification. RFID is
one member in the family of Automatic Identification and Data Capture (AIDC)
technologies and is a fast and reliable means of identifying just about any material
object. This project can be used for security purpose where it gives information about
the authorized persons and unauthorized persons. This can be applied in real time
systems as such in recording the attendance, in the companies and in industries to know
who are authorized. RFID is increasingly used with biometric technologies for security.
Primarily, the two main components involved in a Radio Frequency Identification system
are the Transponder (tags that are attached to the object) and the Interrogator (RFID
reader). Communication between the RFID reader and tags occurs wirelessly and
generally doesnt require a line of sight between the devices.
RFID tags are categorized as either active or passive. Active RFID tags are
powered by an internal battery and are typically read/write, i.e., tag data can be
rewritten and/or modified. An active tag's memory size varies according to application
requirements; some systems operate with up to 1MB of memory. Passive RFID tags
operate without a separate external power source and obtain operating power
generated from the reader. This project uses passive tags. Read-only tags are typically
passive and are programmed with a unique set of data (usually 32 to 128 bits) that
cannot be modified. The reader has three main functions: energizing, demodulating and
decoding. The antenna emits radio signals to activate the tag and to read and write data
to it.

Here we are using RFID based security scanning system to check the Luggage in
highly secured areas like Airports, Railway Stations, in various places where security is
primary concern. Here we are placing the Luggage bags which are to be scanned.
The significant advantage of all types of RFID systems is the non
contact, non-line-of-sight nature of the technology. Tags can be read through a variety of
substances such as snow, fog, ice, paint, crusted grime, and other visually and
environmentally challenging conditions, where barcodes or other optically read
technologies would be useless. This project can provide security for the industries,
companies, etc.
This project uses regulated 5v, 500mA power supply. 7805, a three
terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is
used to rectify the ac output of secondary of 230/12v step down transformer. The RFID
module requires a separate +5v power supply.
