  . Secure and user-friendly interface

• Technologies Used
  - Hardware:
  . Arduino Mega
  . RFID module (card & tag)
  . LCD screen
  . Servo motors (for product dispensing)
  . Keypad
  . Buzzer
  . Power supply
  . Leds

  • Software:
    . Arduino IDE
    . C++ for embedded programming

• How to Use
  - For Customers:
  . Swipe your RFID card to make a purchase.
  . Select the desired product using buttons.
  . Retrieve the product from the dispensing slot.
  - For Vendors:
  . Swipe your vendor RFID (card/tag) or enter the password.
