The passive RFID card is a tiny piece of technology that helps us to track lots of different stuff. RFID is short for Radio Frequency Identification. “ This means that these cards communicate with other devices using radio waves. The notable feature of passive RFID cards is the absence of a battery or any power source. Instead, they feed off the energy the device that is reading them, whether that's a scanner, reader, et cetera. Or when a scanner sends out a signal, the RFID card absorbs that energy and transmits information back. That is how card and reader communicate!
So, assume you have a library book that contains a passive RFID tag. When you check out the book at the library, there is this special scanner that scans the tag that's actually on the book. The scanner reads the tag’s information and stores it in the library’s computer system. Now, the library is aware that you checked out that book. Later, when you return the book, the scanner scans the tag one more time. It reads the tag and knows to register that the book is returned to the library. This is just one of many ways a passive RFID card can track items and make life easier for us all!
The advantages of passive RFID cards are countless! These objects allow us to track key items, help streamline the shopping experience, and provide us with an additional level of safety through security badges. For instance, when you check out a book, the library can easily track who has it and when it should be returned. Because RFID cards require no batteries or charging, they are extremely low-maintenance. That means you’ll never have to replace them very often. They can last a long time! Additionally, these cards are typically quite small, so they’re easy to carry in your pocket or on a keychain.
