RFID stands for Radio Frequency Identification which is a very effective and modern system of finding and identifying objects or even organisms. RFID has a lot of uses and is applied to various fields such as criminology, law enforcement, office application etc. It works by 'tagging' and object with either a passive or active tag which can be identified by a RFID reader using radio waves. The tags are powered by the RFID receiver and are only activated when the tag is in range of the receiver. An RFID tag consists of a data sequence encased in the tag housing and is responsible for the identification of the object. The identification sequence starts when the RFID tag comes within the range of the receiver. The receiver will then pick up the tag's signal and decode it for reference. The RFID receiver will then refer the tag's data to its database to verify the identity of the tag's wearer. Once the tag's data (example: the location of the object, time of verification etc.) is processed and the identity of the object is verified, then the data can be complied in to a larger data set and can be later passed on or processed by another RFID application.(RFiDa.com, n.d.).

Figure 1: "This diagram explains the basic schematic of all RFID systems.The Tag or Transponder can be either active or passive. It responds to a signal from the Interrogator (reader/writer/antenna) which in turn sends a signal to the Computer" (High Tech Aid, 2006b).

An RFID tag is basically composed of an IC. The IC has a small built-in memory (memory type for an IC is usually ROM or Read Only Memory) capacity and may be equipped with a small processor.
