RFID Technology & Application

Radio Frequency Identification (RFID) is a kind of technology using radio waves to identify individual items without physical contact automatically. A typical RFID system contains 3 basic components: Reader, Antenna and Tag.

Barcode is the most common technology which employed for identification. But RFID is more advance in identification down to individual items. The following is comparison of RFID and Barcode.

The information shared is come form the following seminar which organised by Hong Kong Society for Quality (HKSQ) on 23rd Feb 2008.

The history of RFID development:

Some application example are shown as follows:

In Hong Kong Jockey Club, RFID is used for tracing the position of horses during race.


Some manufacturers are using RFID to trace their product during production.

For asset management, the hi-tech equipment is traced in different production line and location.

Warehouse management is also popular to employ RFID.


Hong Kong Polytechnic University had obtained patients for RFID deployment.

The chairman of HKSQ (Dr. Albert Tsang) presents souvenir to the specker (Dr. S.K. Kwok).

Then, we visit the laboratory and observe some real products.
