Things to Know About the RFID Readers
The RFID is actually the acronym which means radio frequency identification. This is one continuously evolving technology which is an automatic identification system which would facilitate the detection of particular objects. The purchases are going to be made much easier through the use of the bar codes with RFID tags which are also known as smart labels. Those RFID tags are actually intelligent bar codes which may interact with the networked system to track each product which has been put inside that shopping cart. They would have two types which are the inductively coupled RFID tags and the others are the capacitively coupled RFID tags.
Well, if you are not quite familiar how such works. The primary function of the RFID reader is actually to transmit data with that RFID tag through emanating such radio waves by the use of the antenna. Those RFID readers are being categorized through their range such as the UHF which stands for ultra high frequency and the HF which is high frequency. These are 13.56 MHz and 2.45 GHz. Moreover, you have to know that the prices are actually dependent on the ranges and for this reason the UHF readers are most expensive but the costs would range from 2500 to 3000 dollars.
The RFID system actually has specially designed RFID tags, edge servers, readers, middleware as well as the application software. Also, the system functions through transmitting that data which is stored in the tags to that RFID reader which in turn would read and processes the data based on the specifications of the application. Such transmitted data may possess information regarding the tag’s locations or those specifics that actually concern the product being tagged. Also, the system has that interrogator that has a particular range wherein this would detect the RFID tag and it also activates it and gets the response. These RFID tags are widely used for so many purposes across various sectors.
Well, there are actually three reasons why these readers are quite expensive. The first is that there is no integrated circuit integration and also there is such low quantity in its production. Lastly, there are those customized components which are not available. But, based on the new calculation done by a particular research company, the cost of such UHF readers may decrease because more dealers are going to invest into this kind of technology. Moreover, as the requirement levels would increase, the costs of the component would also decrease.
There is that new analog front-end IC that was launched by the Colorado-based company which actually works for 13.56 MHz RFID readers. It was this company that introduced the RFID Demonstration Reader. This can be used as the reference design as well as development tool kit.
That Radio Frequency Identification keeps evolving as a technology which has made the foray into the lives of people quite rapidly. The RFID is certainly a technology which has a bright future and this is able to provide a lot of benefits to mankind.
