Radio Frequency Identification Technologies Principles

Recently, the radio frequency prediction and the identification of the technology has grown up from bottom to top in many appliances which are helpful to control the speed variation property of the manufactured things and the materials. Radio Frequency Identification is also helpful for the identification of an object from a distance.

A line sight is not required for this phenomena. Radio Frequency Identification Technology supports most of the unique personal and group IDs and stores the personal data of the recording in it. It is also helpful in searching and incorporating the additional and extra data which is not required for all the process. For example, product key type manufacturer, and It also calculates the environmental factors for example temperature.

 Additionally, Radio Frequency Identification Technology systems also concern with a number of various tags which are situated at the same basic area, unlike the human assistance. Oppositely, suppose a major and big counter which is used for the checking out purpose. Here one can orient the every bar which is in coded item state towards the checker before another process such as processing, manipulating or scanning it. One question here which arise in our minds in that why the duration of near about fifty years is required for the establishment and the mainstream of this system. There can be many logics and reasons for this type of question.

 But the basic reason is cost involvement. For the logical and electronic prediction technologies which also have the ability to compete for the very high price of printed logical symbols. For the recovery purpose, their cost should be low enough to survive the other technologies in the field Radio Frequency Identification Technology is expensive if compared with the traditional logical labeling technologies. It also includes the many other values such as the taxes and retail prices for the consumer facilitations. The main principles of Radio Frequency Identification Technology are discussed here.

 It provides the basic idea about the technologies and their applications. It also tries to meet the different challenges in the organizational field and it proves its role in the development of the technology. Radio Frequency Identification Technology is also applied to the process of data capture. 

It is an automatic and complete process. Some of their comparisons are given in the table below.

Radio Frequency Identification Technologies Principles:

As a lot number of Radio Frequency Identification Technologies occur but at this  peak level the Radio Frequency Identification Technologies are classified into two types which are given below:

     1.      active

     2.      passive.

In the Active technology type tags demand for a complete power source. Energy stored battery or powered infrastructure is connected with them. For the passive type technology the lifetime of the tag is bounded through the process of stored energy.  It is helpful for balancing opposite to the different  number of read operations through which the device can go into the running condition. There are different examples for such system. One of the important example for the active technology tag is that in this type the transponder is completely combined with the aircraft. This transponder predicates the national basic origin and it also is helpful for its running purpose.

Passive Radio Frequency Identification Technologies are also important and have a great value. In this type the series of tags do not need the batteries or any other source for their operation or maintenance. These series of tags have a definite and indefinite life of operation. The passive series tag have  three parts. These parts are

  Ø  antenna

  Ø  semiconductor chip

      Ø  encapsulation.

In this the chip is connected with the antenna and it is made up of the semiconductor. The series of the tag which is used by the reader give permits either to connect the power or not for the communication system. The series of tag antenna focuses and captures the energy source and manipulates the tag’s ID. The encapsulation keeps the integrity of the tag in the same condition and provides protection to the chip and the antenna from different natural environmental disaster conditions such as air, warming due to sun etc.

Two basic various Radio Frequency Identification Technologies

 design and structure meets to eliminate for transferring the power source from the reader site to the series of tag. There are two types which are

                        I.            magnetic induction

                        II.            electromagnetic wave capture

These are the basic main two parameters which proof that EM properties concerning with are better than the RF antenna.
