Tags (or chips) consist of two parts:
1) Antennae 2) Processor/ storage
Receives signal from reader and gives a return signal with ID numberReader sends number to database or server
WORKING OF RFID
ACTIVE: Tag signal availability of 100ft.HIGH signal strength VERY LOW required signal strength from the reader
example : Railway cars on a trackSEMI- PASSIVE:
Tag signal availability only within field of readerLOW signal strengthLOW required signal strength from the reader
PASSIVE:Tag signal availability < 10 ft.VERY LOW signal strengthVERY HIGH signal strength required from reader
example : Retail Checkout ( Widely used because very cheap to make)
TYPES
Advanced Product TrackingReal- time data managementDramatic benefits to manufacturing process
Quick Convenience Grocery Store, Library, HospitalInstant identificationTime saver
Safety and SecurityLocate/identify missing persons Monitor prisoners
Easy AccessAccess by authorized personnel onlyEase security concerns
APPLICATIONS
Does not require human to manually pass item over scanner.More accurate inventory count.Can be incorporated into product, person, animal.Can track each individual item.

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
Attendance Register .
Attendance Register now, easily uploaded to Database.
