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.
