The read range of High Frequency (HF) RFID systems typically ranges from a few centimeters to about one meter. HF operates at frequencies around 13.56 MHz. This relatively short read range makes HF RFID suitable for applications where close proximity reading is required, such as access control and payment systems.
RFID is a broad technology using radio waves for identification. HF is a specific frequency band within RFID. HF RFID operates at 13.56 MHz and has a shorter read range. It's good for close-proximity applications like access cards. Other RFID bands have different characteristics and applications.
