Introduction

2. What is RFID? Radio Frequency IDentification
Contactless communication between objects
Communication by reflected power
Can identify objects in communication range

3. History of RFID World War II (1939~1950) Oct. 1948 1960 ~ 1970
IFF (Identity：Friend or Foe) used in U.K. Air Force
Oct. 1948
“Communication by Means of Reflected Power” proposed by Harry Stockman (Senior of the Institute of Radio Engineers)
1960 ~ 1970
First RFID business application “Electronic Article Surveillance (EAS)” published

4. History of RFID 1990 ~ 2000 2000 ~ present
The organization EPCglobal is set up by EAN and UCC to achieve worldwide adoption and standardization of Electronic Product Code (EPC) technology
2000 ~ present
Wal-Mart uses RFID techniques for tracking goods in supply chain
RFID techniques are used in open system

5. RFID Components
Tag
The data carrier that can attach to goods, pallets, containers or be carried by people
Composed by silicon chip and antenna
Usually communicate with Reader passively

6. RFID Components Interrogator (Reader)
Send radio frequency signal to activate Tags and to communicate with Tags
The device for reading, writing or doing other operations with tags

7. Classification of Radio Frequency
Low Frequency (LF)
125KHz, 135KHz are used
Lower interference by metal and water
Lower reading range
Lower data transmit rate
High Frequency (HF)
13.56MHz is used
Higher data transmit rate than LF
Capable for reading multiple tags at a time

8. Classification of Radio Frequency
Ultra High Frequency (UHF)
433MHz, 860~960MHz are used
Lower antenna implement cost
High reading range
High data transmit rate
High interference by metal and water
Microwave (MV)
2.45 GHz is used
Highest reading range
No standardized

10. Classification of Tag Capability
Passive Tag
Activated by Reader
Low cost and communication range
Semi-Passive Tag
Built-in battery but communicating passively
Higher communication range and data transmit rate
Active Tag
Built-in battery and communicating actively
Highest communication range and data transmit rate

11. Pros and Cons of RFID Pros Cons
Larger data storage space, and data is editable
Read multiple Tags at same time. Higher efficiency
Tag can encapsulate to protect environment impact
Cons
Higher cost
Easy influenced by water, metal, and environment conditions
