What is RFID? 
RFID (Radio Frequency Identification) "Radio Frequency Identification and Identity"

RFID technologies, objects, or creatures with the help of radio frequency identification utility. Active / passive RFID tags used in identification of objects or living things. 125-134 kHz (Low Frequency) (LF), 13.56MHz (High Frequency) (HF), 865-868 MHz (Ultra High Frequency) (UHF) and 2.45 GHz (Micro Wave) systems running on different frequencies are used.

History of RFID 
The first examined the history of the use of RFID for military purposes in 1926 and seen that. In 1926 the II. The use of World War II that was used for the purpose to distinguish between friends and enemies.

System Components
           1.RFID Label:
RFID tag, an RFID chip set with the appropriate application and implementation of capacity taking into consideration the difficulties that the working conditions (temperature variations, chemicals, pulses) and more powerful chips more powerful antenna adapted to work in difficult conditions is the coating. 

          2.RFID Antenna:
RFID antennas, introduced by the radio frequency tag with information on the label located on the chip to the reader transmit antenna, taking as a result of the reflection. Antennas power, reading the shape (linear, circular) and a reading area (away from the reading, close the reading) are found in different models

          3. RFID Reader:
RFID reader antenna transmits signals from the application layer in accordance with specific protocols. Although the user terminal in the form of fixed RFID readers are readers. Hand terminals are integrated RFID antenna. RFID readers can be connected to the antenna 1-4. RFID readers with antennas connected to power can be adjusted separately.

        4. Middleware Application :
Between the RFID reader working with the application and system architecture, the most important element of the Middleware Application (Middleware), is completely reader management, knowledge management and antenna management performs read the label. The reader to read about the method, the network configuration, the antenna settings, perform, read, and which antenna Determination of which are performed by the reader, such as middleware application can perform many operations. RFID Middleware Application protocol based on the most important issue here. Each reader of a protocol and its own middleware architecture that has a running according to the protocol. But the rapid development of RFID technology throughout the world as a result of a standard set by the EPC and RFID readers LLRP (Low Level Reader Protocol) was adopted as the underlying protocol. LLRP if the RFID application in accordance with the LLRP compliant enhanced system can include all the reader and do not need any changes in your application. But any reader to follow its own protocol, then you include in this system is developed in accordance with the readers must be the same brand. LLRP RFID applications and established systems should be claimed as a necessity to live in the future developments should be designed in mind.

RFID Tags :

3 types of RFID tags: passive (inactive), semi-passive (semi-active) or active (active). Passive tags do not own power sources, work with the power of the RFID reader and a cheap RFID tag. In contrast, the semi-passive tags, the signal power from the need to leave a small battery attached. The larger area of the label reads more reliable as they are, they can respond more quickly to the reader. Active tags, on the other varieties in different stages of their power supplies have run to produce a response signal. This exhibit features a high performance, but costs are higher.

Do all countries use the same frequencies? 
Many countries have systems of 125 kHz or 134 kHz low frequency (LF) has determined the range. 13.56 MHz (HF) frequency of the high-frequency systems are used all over the world. However, the 902-928 MHz UHF RFID systems used in the United States, Europe 865.6-867.6 MHz range for the Class 1 Gen 2 protocol were determined. In our country, prepared by the Telecommunications Authority and published in the Official Gazette No. 26464 dated 16.03.2007 "Short Range Radio (KET) Regulations "in accordance with the RFID readers 100mW maximum power with the frequency band 865-865.6, 865.6-867.6, and 867.6-868 MHz frequency band with a maximum of 2W power band can be used with a maximum of 500 mW power. EPCglobal Gen 2 standard set by the frequency of this frequency arrangements range, and the use of force in our country is impossible.

Standards in RFID Turkey
Regulate the use of spectrum in Europe, the European Postal and Telecommunications Union (European Conference of Postal and Telecommunications Administrations - CEPT), UHF is a new European standard for RFID unanimously decided in September 2004.

This standard RFID 865 to 868 MHz frequency band, Listen Before Talk (LBT) protocol provides for the use with power levels up to 2 W. This standard has been adopted in many European countries are located, and local regulations.

In our country, published in the Official Gazette No. 26464 dated 16.03.2007 "Short Range Radio (SRD) Regulations" in accordance with the RFID readers 100mW power in our country with the maximum frequency band 865-865.6, 865.6-867.6 and 867.6-MHz frequency band with a maximum of 2W power 868 bands will be available with a maximum of 500 mW power. This frequency allows the importation arrangements EPCglobal Gen2-certified readers.

Electronic Product Code (EPC), What is?
Supply chain is a particular unique number that identifies the product unique. This number is a pallet, case or a single unit can be used to define.

        What is the EPC Class 1 Gen 2?
EPCglobal, EPC global dimension with the use of RFID technology is used to regulate the product definition, RFID tags and readers for use in Class 1 Gen 2 (Class 1 Generation 2) standard that has developed and has set the standard around the world to implement the various frequency ranges.
