While NFC (Near Field Communication) and Wi-Fi enabled cards offer several benefits, they also pose certain security threats. Here are some of the potential threats associated with NFC/Wi-Fi enabled cards:

  1. Skimming: Skimming is a type of fraud where criminals use a small device to read your card information from a distance. With NFC-enabled cards, skimming is possible if the criminal is close enough to your card. Wi-Fi enabled cards, on the other hand, are more vulnerable to hacking attacks that can allow criminals to steal card information from a distance.
  2. Malware and Hacking: Wi-Fi enabled cards are particularly vulnerable to hacking attacks. Criminals can use malware or phishing attacks to gain access to your device's Wi-Fi connection, and then intercept your payment information as it is transmitted wirelessly.
  3. Lost or Stolen Cards: NFC and Wi-Fi enabled cards can be easily used if they are lost or stolen, particularly if your device is not password-protected or if your card information is stored on an unsecured app or device.
  4. Fraudulent Transactions: Criminals can use your stolen NFC/Wi-Fi enabled card information to make unauthorized transactions or purchase goods online.
  5. Denial of Service Attacks: A denial of service (DoS) attack occurs when a criminal floods the payment terminal with fake payment requests, causing the system to crash or become overloaded. This type of attack can disrupt payment systems and make it difficult for legitimate customers to make payments.

To minimize these threats, it is important to keep your NFC/Wi-Fi enabled cards safe, regularly monitor your accounts for any suspicious activity, and only use trusted payment terminals. Additionally, you can protect your card information by enabling security features such as password protection and two-factor authentication. Finally, always keep your card's software and security features up to date to ensure maximum protection against potential threats.
