4. Tags (or chips) consist of
two parts:
1) Antennae
2) Processor/ storage
Receives signal from
reader and gives a return
signal with ID number
Reader sends number to
database or server
WORKING OF RFID

5. ACTIVE:
Tag signal availability of 100ft.
HIGH signal strength
VERY LOW required signal strength from the reader
example : Railway cars on a track
SEMI- PASSIVE:
Tag signal availability only within field of reader
LOW signal strength
LOW required signal strength from the reader
PASSIVE:
Tag signal availability < 10 ft.
VERY LOW signal strength
VERY HIGH signal strength required from reader
example : Retail Checkout
( Widely used because very cheap to make)
TYPES

6. Advanced Product Tracking

 Register Table with attendance check
 Server interface with the devices via IP address.
Retrieved text file from the device

13.  This project is a full system for student monitoring in colleges, and
high education institutes.
 The system support two different types of outputs :
USB flash memory, and Ethernet.
 The device is supported with friendly using software for data analysis
and previewing .
 Lecturers need no more wasting time, and effort to have their
