Card Security & Fraud Protection
Card networks, issuers, wallets and banks all include multiple layers of security. Here’s a quick, simple guide to how they protect you — and what you can do to stay safe.
Layers of card protection
Network-level
Visa, Mastercard, AmEx and others score every transaction for risk using global data.
Issuer-level
Your bank or card provider runs its own fraud engine with device data and behavioural checks.
Wallet-level
Apple Pay / Google Pay hide your real card number and use biometrics for every purchase.
Most common fraud types
- Stolen card details used online.
- Fake merchant sites designed to capture card numbers.
- Phishing emails pretending to be your bank.
- Skimmers on ATMs (less common now).
- Social engineering scams.
How to stay safe
- Use a wallet app (Apple/Google Pay) whenever possible.
- Never send card pictures or codes to anyone.
- Freeze your card in the app if something looks off.
- Use strong biometrics (FaceID, fingerprint).
- Check your statements regularly.
