Radio Frequency Identification (RFID) chips is small devices that help track and identify things using radio waves. They get used in lots of ways, like in shops for watching products, in libraries to handle books, and even in hospitals for checking equipment and patients. RFID chips come in two main kinds: passive and active. Passive ones don't have battery and they get power from the reader, while active chips has their own battery and can send signals farther. At FUWIT, we know how key this RFID tech is for companies now, and we want to help you figure out picking the right chip for what you need and where to get good quality ones at fair prices.
