The development of IOT(Internet of Things) are rapidly and widely. Most scientists are talking about the asset management that RFID tags will be applied to and the benefits of the application.

So what is the cattle ear tag and how does these RFID tags work on asset management mostly in super farm on livestock? 

Let's talk about it.

Radio frequency identification (RFID) describes a system that wirelessly transmits the identity of an object, in the form of a unique sequence of numbers or letters, using radio waves. Although there are several types of RFID systems, this fact sheet describes the technology used in passive, low frequency RFID tag systems. This is the technology first used in USDA-approved RFID ear tags for cattle which we called as cattle ear tag.

There is no requirement for cattle producers to electronically read RFID ear tags. However, many producers will find benefit in automating data entry and retrieval by utilizing a RFID system in their management. The four basic components of a RFID system as used in animal identification are: (Figure 1).

• Transponder - The transponder is the electronic data source that stays with the animal you want to identify. The transponder contains a microchip, where the identification number is stored. The transponder is embedded in the ear tag.

• Transceiver - The transceiver (or reader) is used to retrieve the information stored in the transponder. This device is essentially a radio transmitter and an antenna. The transceiver could be part of a hand-held unit that is taken to the location of the animals with the RFID tags or a stationary unit that the animals pass by.

• Data accumulator - This is a device where information received by the transceiver is accumulated or stored. This could be a computer, personal digital assistant (PDA), scale head or a variety of other electronic devices.

• Processing software - This software transforms the accumulated data into recognizable and useful information. In the case of animal identification, the useful information would be a 15-digit number that is unique to that animal. In a separate process, this information could then be imported into a variety of data management programs.

Transponders used most commonly in RFID animal identification systems are called inductively coupled transponders. What it means is that energy to run these types of transponders is supplied by electrical currents produced by electromagnetic fields created by components embedded in the transponder. There are three parts to a typical inductively coupled RFID transponder (Figure 2):

• Silicon microprocessor or microchip - These microchips are the data source component of the RFID. The microchip contains a unique 15 - digit Animal Identification Number. Passive RFID tags are not able to store additional information.
