8. Safety and Security: Card Fraud

What is Card Fraud?

Card fraud happens when someone uses your card information without permission. Think of it like someone stealing the keys to your house and opening it when you’re not there. Below we explore three common ways fraudsters get those “keys”: shoulder surfing, card cloning, and key logging.

1️⃣ Shoulder Surfing 👀

Analogy: Imagine you’re writing a secret note in a crowded café. A person sitting next to you watches the paper and copies the message. That’s shoulder surfing—someone watches you enter your PIN or card details.

• Common places: ATMs, ticket machines, online check‑outs.
• How it works: The fraudster simply looks over your shoulder or uses a camera to capture the numbers.
• Prevention tips:
  1. Cover the keypad with your hand when typing a PIN.
  2. Choose a seat far from the screen or use a privacy screen.
  3. Be aware of people standing too close or taking photos.

2️⃣ Card Cloning 🛠️

Analogy: Think of a key that can be copied. If someone takes a picture of your key’s pattern, they can create a duplicate key that opens the same lock. Card cloning is the same—someone copies the magnetic stripe or chip data from your card.

• Common methods: Using a cheap reader/writer device to scan and copy the card data.
• How it works: The device reads the magnetic stripe or chip, stores the data, and writes it onto a blank card.
• Prevention tips:
  1. Keep your card in a protective sleeve that blocks magnetic fields.
  2. Use cards with EMV chips whenever possible; chips are harder to clone.
  3. Report lost or stolen cards immediately.

3️⃣ Key Logging 🔑

Analogy: Imagine a secret diary where you write down your password. A keylogger is like a tiny invisible hand that copies every letter you type into the diary. It records your PIN, passwords, and other sensitive data.

• Common places: Public Wi‑Fi hotspots, infected computers, malicious apps.
• How it works: Software (or sometimes hardware) records keystrokes and sends them to a remote attacker.
• Prevention tips:
  1. Use reputable antivirus and keep software updated.
  2. Never log into sensitive accounts on public computers.
  3. Enable two‑factor authentication (2FA) so even if a keylogger captures your password, the attacker still needs a second code.
