RFID full meaning is Radio Frequency Identification. Through it, it is possible to detect radio frequency from the distance by utilizing the frequency. At present, instead of the bar code on different products, this type of information identification system is being used, which is known as rfid tag. This will allow the user to get information about radio frequency, regardless of where the product is available. It is also thought of using this ID as an electronic passport. But there is a debate that such an identification system may violate the user’s confidentiality of the product or passport.
One and a half years ago, we read a news in Bangladesh. It was possible to recover the stolen car and through rfid. The car was fitted with rfid. As a result, it was possible to identify its location via radio frequency or radio waves. For safety, rfid’s are fitted in the car so that it is not easily open. So, the rfid module is a good arrangement for security
