Passive RFID tag with low frequency range is used for this application, since it is economic. Here we need short ranged and economic tags for better results. LF range RFID is the ideal choice for this constraint.(Sariff, N., Buniyamin N.)

Regardless of the frequency, method of communication, or the power supply, the goal of any RFID system is to enable specific data to be transmitted between a portable device and the tag, and then be processed and used accordingly. RFID systems are used for objects which get lost, stolen often, underutilized, or difficult to locate in a timely manner.

While the Radio Frequency Identification Device has been in existence for almost 50 years, the use of this chip in human beings is an advancement of the technology. The chip has mainly been used for tracking animals and goods throughout is existence. Generally, the RFID chip consists of two main parts i.e. an antenna and integrated circuit chip. It's been used as an effective detection mechanism since the antenna can recognize the chip regardless of whether it's within its line of sight (Alam, 2011).

Several methods of fully digitalizing this process have been suggested, the Radio Frequency Identification (RFID) being one of the major methods thought of.

RFID is an abbreviation of Radio Frequency Identification and it is one of the top 10 supply chain technology trends (Intermec Technologies Corporation, 2007). History of this technology or where it first evolves is still vague, but there are consensus among expert stated that it first used and developed to identify the enemy aircraft during the World War 2 which known as (IFF) Identification: Friend or Foe System (Ward & Kranenburg, 2006).

RFID (radio frequency identification) is an new technology that threatens to take the place of bar codes in the supply chain world. The technology uses electromagnetic fields to automatically identify and track tags attached to objects. This innovation can provide many benefits in logistics and may revolutionize the entire industry. But, even though the technology provides many benefits, it also has many drawbacks and may not yet be developed enough to become the industry standard. The technology also may not be beneficial or cost effective for every business and will require a total overhaul of a businesses infrastructure, which can be extremely costly. Furthermore, both bar codes and RFID technology have many pros and cons, also industry may not be ready to implement RFID into their infrastructure.

A passive RFID tag, more commonly used, is one that is not connected to a power source. These tags rely on the electromagnetic field that is generated by specific RFID tag readers to create enough electrical charge to transmit the stored data in radio waves (Venkateswara, 2011).

RFID is the wireless non-contact use of radio-frequency electromagnetic fields to transfer data. The purposes of automatically identifying and tracking tags attached to objects. Since RFID tags can be attached to clothing, possessions, or

They also have a fast response time and the cost effectiveness, life time and low maintenance are some important benefits (using passive tags) because no batteries are needed. Some examples are given in Miller et al. (2006), Ni, Liu, Cho, and Patil (2003) Patil, Munson, Wood, and Cole (2005). These systems use RFID as a supporting or calibration system, secondary to main technology (radio frequency, INS, etc.). Instead, our system is completely based on passive RFID technology.

Radiofrequency identifies the subject by reading the tags attached to the subject. These tags contain electronically stored information which is captured by the reader. Tags may either be powered by electromagnetic induction, some may collect energy from the interrogating radio waves and act as passive transponder and some are powered by batteries and can operate at hundreds of

Barcoding is governed by Universal Product Code UPC whereas RFID is governed by electronic product codes EPC. In its evolution Barcodes were categorized as 1D, 2D and 3D with increasing capacity to store information like manufacturer, product type, batch number etc. Similarly RFID has Active and Passive tags that are being chosen according to the necessity and level of security. An Auto-ID system implementation to a warehouse or a facility takes into account strategic,

For addressing these problems, few other techniques have been proposed which includes such as Radio frequency identification tag or RFID, encrypted bar codes (1D and 2D). Bar codes (1D) contain the linear lines of different width arranged parallel in different sequences depending upon the code associated with it. Similarly, 2D barcodes contain rectangles of different dimension arranged in matrix form and, each rectangle denotes a character. Thus, the combination of rectangles arrangement in 2D square matrix makes a unique code for identification. Information related to the product can be uploaded on a central server and coupled with the code given on product barcode. Therefore, information regarding any product can be accessed using code generated by scanning barcode. Similarly, they are very useful in product tracking in supply chain. The labels having barcode are easy to produce by simple printing on paper or polymeric film which can be attached or sewed to the fabric. For avoiding the

Abstract— Unauthorized and uncertified small sea going fishing crafts are being used for criminal activities in the coastal areas. Using this uncertified crafts illegal benefit provided by the government also is availed by the crooked persons. RFID is a forthcoming technology which provides promising opportunities for the implementation of new services in vessel monitoring and secure authentication. Radio Frequency Identification (RFID) is an inclusive wireless system which transmits unique identity code using radio waves. This technology is mainly used to identify objects attached with tags and it consists of a reader, tag and wireless channel. The reader and the tag both have a microchip and an antenna is there to perform handshaking mechanism when they both communicate. A tamper evident Automated Security Registration plate (ASRP) using RFID tag is designed here to provide secure

Since the invention of computers, they are used to process raw data, analyse and display converted data into useful information to the end users. Entering the information about an item requires repeated data entry which can be burdensome, costly and error-prone. Because of this, many automated system were introduced to perform this data entry task. These systems are referred to as automated identification systems. An example of application areas including the swipe card access system, the on board computer systems used in delivery and the Product identification in food supply chains.

Passive tags can be either battery or non-battery operated, as determined by the intended application. Passive tags reflect the RF signal transmitted to them from a reader or transceiver and add information by modulating the reflected signal. A passive tag does not use a battery to boost the energy of the reflected signal. A passive tag may use a battery to maintain memory in the tag or power the electronics that enable the tag to modulate the reflected signal.
