What Is Radio Frequency Identification Tag (RFID Tag)?

You may have wondered what was happening if you saw a dog in the park with a chip on its collar. Well, it's pretty simple! That chip is an RFID tag, and it's used to keep track of your dog (or other pets) whenever you take them out for a walk. An RFID tag is an electronic device that can wirelessly transmit data to a radio frequency identification (RFID) reader. Instead of manually scanning an ID card or waving your hand over a scanner whenever you want to access something like your office or car, an RFID tag allows for automatic recognition by simply being near the proper device. This technology has been around since the 1950s but only recently started being used in consumer products such as credit cards and key fobs. It has also been used in things like toll tags in Europe since the 1990s; however, it wasn't until recently that they became available in North America—and they're still pretty new here! RFID tags are like your best friend—the one who always knows when you're in trouble and can't stop talking about how great he is. They're the ones you can count on no matter what, and they're the ones who are there for you when you need them the most. What makes them so great? They're made up of at least two main parts: an antenna, which receives radio frequency (RF) waves, and an integrated circuit (IC), which is used for processing and storing data and modulating and demodulating RF waves. So why should we care about these two little pieces? Well, because they make our lives easier! The antenna sends a signal to your laptop, which tells it that there is something nearby—and then the IC takes this signal and processes it into information that can be read by whatever device is receiving it.
