- 3. RFID ◦ RFID = Radio Frequency Identification ◦ Electronic labeling and wireless identification of objects using radio frequency ◦ Tag carries with its information ◦ a serial number ◦ Model number ◦ Color or any other imaginable data ◦ When these tags pass through a field generated by a compatible reader, they transmit this information back to the reader, thereby identifying the object
- 4. RFID components ◦ A basic RFID system consists of these components: ◦ A programmable RFID tag/inlay for storing item data; ◦ Consisting of an RFID chip for data storage ◦ an antenna to facilitate communication with the RFID chip ◦ A reader/antenna system to interrogate the RFID inlay ◦ Application software and a host computer system
- 5. RFID Tag ◦ The RFID tag consists of an integrated circuit (IC) embedded in a thin film medium. ◦ Information stored in the memory of the RFID chip is transmitted by the antenna circuit embedded in the RFID inlay via radio frequencies, to an RFID reader ◦ 3 types ◦ Passive ◦ Semi-passive ◦ Active
- 6. Types of RFID Tags Active Tags • Use a battery • communicate over distances of several meters Semi-passive Tags • Contain built-in batteries to power the chip’s circuitry, resist interference and circumvent a lack of power from the reader signal due to long distance. • They are different from active tags in that they only transmit data at the time a response is received Passive Tags • Derive their power from the field generated by the reader • without having an active transmitter to transfer the information stored
- 7. Applications Frequency Appx. Read Range Data Speed Cost of Tags Application Low Frequency (125kHz) <5cm (passive) Low High • Animal Identification • Access Control High Frequency (13.56 Mhz) 10 cm – 1m (passive) Low to Moderate Medium to Low • Smart Cards • Payment (paywave) Ultra High Frequency (433, 868-928 Mhz) 3m -7m (passive) Moderate to High Low • Logistics and Supply Chain • Baggage Tracking Microwave (2.45 & 5.8 Ghz) 10m -15m (passive) 20m – 40m (active) High High • Electronic toll collection (Autotoll) • Container Tracking

- 11. Online Survey ◦ Target: SME ◦ Information: Opinion on RFID and its applications ◦ Site: ◦ http://qtrial.qualtrics.com/SE/?SID=SV_9N5UPRZuyuWtsk4
- 12. Survey Result Logistics and Supply Chain Management 20% Pharmaceutic manufacturing industries 15% Library Management 21% Inventory Control 10% Document Management 8% Security 8% Customer Services 5% Hotel Management 5% Banking and Finance 5% Social Services 3% Other 18% Types of industries that respondents think it is possible to apply RFID technology
- 13. Further Development ◦ In medical uses and library management

- 15. Conclusion ◦ Positive ◦ RFID is a contactless reading technology and can read through other materials ◦ Hold more data than barcode does ◦ RFID tags data can be changed or added ◦ More effective, bring lots of convenience to us ◦ Negative ◦ Cost is relatively remain high (compare to barcode) ◦ RFID signals may have problems with some materials ◦ RFID standards are still being developed
