Tags (or chips) consist of two parts: 1) Antennae

2) Processor/ storageReceives signal from reader and gives a return signal with ID numberReader sends number to database or serverThis all is done using WEIGAND protocol

WORKING OF RFID

WEIGAND protocol

EM 18 reader module

RFID Tags

ACTIVE: Tag signal availability of 100ft. HIGH signal strength example : Railway cars on a track PASSIVE: Tag signal availability < 10 ft. VERY LOW signal strength ( Widely used because very cheap to make)

TYPES

Advanced Product Tracking Real- time data management Dramatic benefits to manufacturing process

Quick Convenience Grocery Store, Library, Hospital Instant identification Time saverSafety and Security Locate/identify missing persons Monitor prisoners Easy Access

Access by authorized personnel only Ease 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.

RFID card is detected by the reader module if it in the range of 10 cm.

After reading the card it checks the database. After checking database it decides that card is duplicate or

not. According to database it controller increases the count

for that specific lecture and store it in database

This project is a full system for student monitoring in colleges, and high education institutes.

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.
