This project focuses on designing a secure Near Field Communication (NFC)-based contactless payment system. The system ensures encrypted communication and strong authentication to prevent unauthorized transactions and relay attacks.
Study NFC communication protocols and contactless payment architecture.
Analyze risks such as relay attacks and signal interception.
Design secure NFC transaction workflow.
Implement encryption mechanisms for NFC data transmission.
Integrate PIN or biometric verification before transaction approval.
Develop secure transaction confirmation protocols.
Log transaction data for audit purposes.
Simulate contactless payment scenarios in a controlled environment.
Test resistance against replay and relay attacks.
Measure transaction speed and system performance.
Document security improvements and limitations.
