RFID ( Radio Frequency IDentification )

Now, let's break down what this means: a system of technologies that allows an object, person or animal to wirelessly identify itself to another object, person or animal. Hence the words RF (Radio Frequency) and ID (IDentification).

RFID subdividing common ways of the technology are by frequency and whether or not the tag is a passive device.

LF (Low Frequency, 58-148.5 kHz)

HF(High Frequency, 1.75-13.56 MHz)

UHF(Ultra High Frequency, 840 ~ 960MHz and 2.4GHz range)
