Week 3 FYP I

Title of activity:

Overview of RFID systems

Objective:

Briefly describing what is exactly RFID (Radio Frequency Identification)

Content/Procedure:

1.   Radio frequency identification (RFID) marks a new development in the Information Society where objects equipped with micro electronics that can process data automatically will increasingly become an integral part of every day life. 

2. RFID is progressively becoming more common, and hence a part of individuals’ lives in a variety of domains such as logistic, healthcare, public transport, the retail trade, in particular for improved product safety  and faster product recalls, entertainment, work, road toll management, luggage management, and travel documents.

3. RFID technology enables the processing of data, including personal data, over short distances without physical contact or visible interaction between the reader or writer and the tag, such that this interaction  can happen without the individual concerned being aware of it.

Conclusions:

1. RFID transfer energy to the transponder by emitting electromagnetic waves through air.

2. Transponders can be read from a distance and from any orientation, thus they do not require line of    sight to be read.

3. RF-Tags can easily be embedded into any non-metallic product. This benefit allows the tag to work in harsh environments providing permanent identification for the life of the product.
