This project uses RFID technology to track and record student's laptop at both entry and exit of school autonomously, and paperless,at the shortest time possible.
RFID-Key Ring 
125KHz
RFID card 
13Mhz
RFID reader 
Raspbery pi 
A breadboard and just a bunch of jumper wires
-
Students register their details
-
All the information from the above interface is saved in the main database.
-
Key and card names are written digitally to the key ring and the card tag respectively.
-
Student carries the key ring and the card tag is attached permanently to the student's laptop
-
At the gate, scanner_1 which only detect cards, automatically detects student's laptop even while in the bag.
-
The system's program pulls students data from the main database based on data from the detected card and stores the data in a temporary database. If the card_data isn't recognized and card is displayed as unrecognized.
-
Student then swipes the low frequency key ring on scanner_2. The system's program then matches the key data with the data in the temporary database.
-
If found, the verification is complete, else the key data is displayed as unrecognized.
