NFC Security
Measures to protect Near Field Communication (NFC) from unauthorized access and exploits.
Understanding:
Near Field Communication (NFC) is a short-range wireless communication technology used for contactless transactions, device pairing, and data exchange. While NFC provides convenience, it is vulnerable to various security threats, including eavesdropping, data interception, and unauthorized access. Attackers can exploit NFC weaknesses to conduct relay attacks, NFC cloning, and unauthorized payments.
Common Applications and Use Cases:
Contactless Payments – Used in mobile payment systems such as Google Pay, Apple Pay, and credit card tap payments.
Access Control & Authentication – Implemented in keycards, smart locks, and two-factor authentication systems.
IoT and Smart Devices – Utilized in IoT applications for quick pairing and secure communication between devices.
Best Practices and Security Considerations:
Enable Secure Elements (SE): Use hardware-based security features for NFC transactions.
Disable NFC When Not in Use: Prevent unauthorized scanning and relay attacks.
Use Encryption & Tokenization: Encrypt NFC data and employ tokenized transactions for secure payments.
Monitor and Update NFC Systems: Regularly patch NFC-enabled devices to mitigate newly discovered vulnerabilities.
