3. Introduction
The ‘smart city’ is the ability to access any application at anytime from anywhere
Smart Cities should implement
e-health
e-government
e-commerce systems
Cities become “Smarter” with
Object Identification
Network of things
High speed Wireless Network
Monitoring by Sensors
Cities become “Green” with
Low power consumption
Shanghai, China, 14 May 2010

4. RFID Technology Object Recognition/ tracking system
RFID system consists
transponder (i.e., the tag itself)
transceiver (i.e., the reader)
To track any object it uses an EPC
An EPC is either 64-bit or 96-bit identifier
Header-2 bits
EPC Manager- 21 bits
Object Class- 17 bits
Serial Number-24 bits H
EPC Manager
Object Class
Serial Number
