RFID - Pros And Cons
The acronym for Radio Frequency Identification is RFID. It is for the purpose of tracking traffic assets and diminishing wild animals that radio frequencies are being used by the RFID technology. The RFID has a unique kind of technology. It is very necessary to understand RFID Pros and Cons before it is utilized. It has similar functions as any other device used for communication purposes. In the form of RFID tags the receivers and transmitters are part of this technology. All necessary information is present on the RFID tags or microchips. The RFID card reader helps in comprehending the information.
On the tags is also present the antenna that allows signal transmission. RFID tags are generally used in two types that are the active RFID tag and the passive RFID tag. Information is transferred to the reader directly by the RFID tag in which a source or external battery is not used. In the case of the passive tags for the purpose of functioning an external power is needed. There are a number of advantages to this technology called RFID. It is very easy to fix the RFID tag on an animal's body to keep track of it in the wild.
These tags prove to be useful in poultry farms and for animal husbandry purposes. Information on animal health, age of animal and vaccinations can be availed of by the use of the RFID tags. As compared to bar codes, this technology is considered far better and replicating it is not too easy. It is due to this feature that the product's security increases greatly. As far as the products logistics is concerned, stock update, transportation, etc is concerned the systems of RFID play a main role in the retail business supply chain management.
Many jewelry shops that use bar codes as a protective tool find that they fail to provide any security as they have been seen to fail often. However, in the recent times the RFID tag latest technology is being used in jewelry shops. These RFID tags are placed inside the jewelry and at the exit doors an alarm is installed. Storage of up to 2 KB is possible in the RFID tag whereas in the bar code technology the code is able to read just about ten to twelve digits. Just as there are advantages there are also a number of disadvantages too.
Installation of the RFID technology is expensive. For many offices and firms run by small and medium scale enterprises it proves a costly affair. In case the tags are installed in metal products and in liquid, reading the information on the RFID tags for the RFID reader becomes difficult. Radio waves are generally reflected by the metal surfaces and liquids, which makes tag reading difficult. To ensure proper reading the tags need to be placed at different angles and alignments which makes task tedious especially in large firms. Even customers can be easily tracked due to which it is felt that this is also an invasive technology.
