- 3. OUTLINE Introduction RFID Internet of things Architecture of IOT RFID system Applications of RFID Challenges of RFID Conclusion References 3
- 4. INTRODUCTION WHAT IS RFID? RFID is an automatic technology. It identify and collect object data through RF signals. First appeared in 1945. RFID system consists of TAGS and READERS. 4
- 5. RFID DEVICES IN DIFFERENT FORMS. 5
- 6. WHAT IS INTERNET OF THINGS? The IOT refers to uniquely identifiable objects ad their virtual representation in an internet. Radio-frequency identification is often seen as a prerequisite for the Internet of Things. 6
- 7. The Internet of Things allows people and things to be CONNECTED 7
- 8. ARCHITECTURE OF IOT. The IOT system architecture is generally divided into three layers. PERCEPTION LAYER NETWORK LAYER SERVICE LAYER 8
- 9. PERCEPTION LAYER It is the information origin and the core layer of IOT. All kinds of information in physical world used in IOT are collected in this layer by sensors and RFID tags. 9
- 10. NETWORK LAYER In this layer the information from perception layer is transported to the next layer. The layer provides an efficient and trusted network platform for upper level. 10
- 11. SERVICE LAYER Data management sub-layer. The data management sub layer processes complex data. Application service sub-layer. The application service sub layer transforms information and provides good user interface. 11
- 12. RFID SYSYTEM Composed of three main components. RFID TAGS. READER. APPLICATION SYSYTEM. 12
- 13. RFID TAGS The essential components of rid tags are ANTENNA. INTEGRATED CIRCUIT. PRINTED CIRCUIT BOARD. 13
- 14. COMPONTENTS FUNCTIONS. The function of antenna is to transmit and receive radio waves for communication. The IC is a packaged collection of components that provide brain for the tag. The PCB is the material that holds the circuit together. 14
- 15. RFID READER The reader is for the communication with any tags in its read range. Two functional blocks High frequency interface. Control system. 15
- 16. APPLICATION SYSTEM Also called data processing system. Initiates all readers ad tag activities. Can be an application or database. 16
- 17. THE RFID CAN BE USED IN THE FOLLOWING FIELDS. Health Care and Medicine. Military and Defense. Transportation. Banking Access control 17
- 18. APPLICATIONS OF RFID TECHNOLOGY RFID for Intervehicular Communication. To monitor traffic and vehicle speed in construction zones or other areas. In Libraries. Libraries have used RFID to replace the barcodes on library items. The tag can contain identifying information. 18
- 19. Payment by mobile phones. Credit card companies developed specialized micro SD cards containing both RFID tag and a reader. After inserting the microSD, a user's phone can be linked to bank accounts and used in mobile payment. Access management. RFID tags are widely used in identification badges, replacing earlier magnetic stripe. Tags can also be placed on vehicles, which can be read at a distance. 19
- 20. LATEST INFORMATION From this July, several hospital in Europe started to use RFID tags to track surgical tools. RFID tags will prevent the loss of surgical instruments and improve patient care. 20
- 21. CHALLENGES OF RFID TECHNOLOGY Collision Problems. Security problems. The cost of the RFID tags are still expensive. 21
- 22. CONCLUSION IOT and RFID defines the future. The IOT uses a variety of information sensing device and information processing equipment. They are combining with internet to form an extensive network to intelligentize the objects. 22
