RFID (Radio Frequency Identification)
Radio-frequency identification (RFID) is a technology that uses radio waves to transfer data from an electronic tag, called RFID tag or label.

It is a superior and more efficient way of identifying objects unlike bar codes and manual systems. [1] RFID tags can be read in multiple at once as long as they are passed within close enough proximity to an RFID reader. They can also be integrated in containers, carton, box or in plastic IDs since they do not require a “line of sight” in order for its’ data to be acquired, thus protecting it from possible damage due to exposure to the environment.

RFID tags are classified into two major types [2] and they are the Active Tag and the Passive Tag. The latter does not use a battery, while the former has an on-board battery that always broadcasts or programs its signal. Passive RFID tags are much more preferred because they are low cost and are much more simple than the Active RFID tags. In Design Projects in [3] and [4], Passive RFID tags are used for the reason that is cost effective and small in size.

RFID readers are classified into two different types [1] with respect to mobility and these are fixed RFID and mobile RFID. If the reader reads tags in a stationary position, it is called fixed RFID. On the other hand, if the reader is mobile when the reader reads tags, it is called mobile RFID. In this project, we will use a Passive tag since we will incorporate it in a school ID thus and a fixed RFID reader since we will implement it in the door.
