BANK SECURITY SYSTEM

BANK SECURITY SYSTEM Module

Aim:

To Design a security system for banks

 

Working Principle:

Here the user has to insert the smart card in to the slot and then type the password via matrix KB. If the passwords match then the Relay based door is opened.

BANK SECURITY SYSTEM

Block diagram Explanation:

Here we are designing a System in which the user has to insert the smart memory card issued by the bank into the slot. After this the user has to type the password via 4*3 matrix KB. The µC will read the password stored in the memory of the smart card and store it in the internal RAM. Then the µC will compare the Kb password typed by the user with the smart card password. If both the password match then the relay based door is opened. If not the buzzer is turned on

  • Is smart card inserted? YES, read the password from memory card and store in RAM
  • Read the password entered from Matrix KB inti internal memory.
  • Compare the smart card password with matrix KB password.
  • Is the passwords match?
  • Yes, Turn ON the relay based door.
  • No, Turn on the buzzer.
