MADOORS RFID (Radio Frequency Identification) “Radio Frequency Identification” RFID technologies are used to identify objects or living things with the help of radio frequency.

Active/passive RFID tags are used to identify objects or living things.

125-134 KHz(Low Frequency)(LF),

13.56MHz(High Frequency)(HF),

865-868 MHz(Ultra High Frequency)(UHF)

Systems operating at different frequencies as 2.45 GHz (Micro Wave) are used.

Madoors rfid vehicle identification identification reading systems, rfid pass system RFID History; When the history of RFID is examined, it is seen that its first use was between 1939 and 1945 and for military purposes. II. The purpose of its use in World War II is to distinguish friend and foe.

Rfid tag reader antenna System Components

1.RFID Tag: The RFID tag is the version of an RFID chip, which is determined with the appropriate application and capacity, and is adapted to work under difficult conditions with a stronger antenna and stronger coating, taking into account the operating conditions in the application (temperature differences, chemicals, impacts). rfid vehicle identification system

2.RFID Antenna: RFID antennas transmit the radio frequency they broadcast and the information contained in the chip on the tag, to the reader as a result of the reflection formed on the antenna on the tag. Antennas are available in different models according to power, reading shape (Linear, circular) and reading areas (far field reading, near field reading).

3. RFID Reader: RFID reader transfers the signals coming from the antenna to the application layer in accordance with certain protocols. Although RFID readers are fixed, there are also readers in the form of hand terminals. Handheld terminals have an integrated RFID antenna. 1-4 antennas can be connected to RFID readers. The power of the antennas connected to the RFID readers can be adjusted separately.

 The most important issue here is the RFID protocol on which the Middleware Application is based. Each reader has its own protocol and a middleware architecture that works in accordance with this protocol. However, as a result of the rapid development of RFID technology all over the world, a standard has been set by EPC and LLRP (Low Level Reader Protocol) has been accepted as the basic protocol for RFID readers.

 If your RFID application is developed in accordance with LLRP, you can include any LLRP compatible reader in your system and you do not need any changes in your application. However, if your application has been developed in accordance with the protocol of any reader, the readers you will add to this system from now on must also be of the same brand. It should be demanded as a necessity in LLRP and RFID applications, and the systems to be installed should be designed with future developments in mind.

 Rfid active tag MADOORS RFID tags are of 3 types: passive (inactive), semi-passive (semi-active) or active (active). Passive tags do not have their own power source, they work with the power of the RFID reader and are the cheapest RFID tag. On the other hand, a small battery is added to the semi-passive tags, which does not require power from the incoming signal. These tags, which have a larger reading area, are more reliable and can respond to the reader more quickly. Active tags, unlike other types, have their own power source that enables them to operate their circuits and generate response signals. With these features, they show high performance, but their costs are higher.

 Rfid tag Are All Countries Using the Same Frequencies? Many countries have specified the 125 kHz or 134 kHz(LF) range for low frequency systems. 13.56 MHz (HF) frequency is used for high frequency systems all over the world. However, while UHF RFID systems use 902–928 MHz in the USA, the 865.6–867.6 MHz range is specified in the Class 1 Gen 2 protocol for Europe. In our country, in accordance with the "Short Distance Access Radio (KET) Regulation" prepared by the Telecommunication Authority and published in the Official Gazette dated 16.03.2007 and numbered 26464, RFID readers are equipped with a maximum power of 100mW in the 865-865.6 frequency band, and a maximum of 2W in the 865.6-867.6 MHz frequency band. and can be used with a maximum power of 500 mW in the 867.6-868 band.

 These frequency arrangements allow the frequency range and power determined by the EPC global Gen 2 standard to be used in our country. rifd active passive tag reader antenna RFID Standards Turkey The European Conference of Postal and Telecommunications Administrations (CEPT), which regulates spectrum use in Europe, unanimously decided on a new European Standard for UHF RFID in September 2004. This standard envisages the use of RFID in the 865 - 868 MHz frequency band with the Listen Before Talk (LBT) protocol with power levels up to 2 W.

 This standard has been accepted in many European countries and is embedded in local regulations. In our country, in accordance with the "Short Range Access Radio (KET) Regulation" published in the Official Gazette dated 16.03.2007 and numbered 26464, RFID readers in our country have a maximum power of 100mW in the 865-865.6 frequency band, a maximum of 2W in the 865.6-867.6 MHz frequency band and 867.6- It can be used with a maximum power of 500 mW in the 868 band. These frequency arrangements allow the import of EPCglobal Gen2 certified readers. What is the rfid system Electronic Product Code (EPC)?

 A unique number that identifies a particular product in the supply chain. This number can be used to identify a pallet, case or single unit. What is EPC Class 1 Gen 2? EPC global has developed the Class 1 Gen 2 (Class 1 Generation 2) standard for use in RFID tags and readers in order to regulate the use of RFID technology used in product identification with EPC on a global scale, and has determined various frequency ranges for the application of the said standard worldwide.
