We’ll explore:
How magnetic stripe cards stored unencrypted data
Why EMV chips are more secure
What happens during a chip transaction
How one-time cryptograms prevent fraud
Why tap-to-pay (NFC) is just as secure
The difference between chip-and-signature vs. chip-and-PIN
The future of biometric and dynamic CVV credit cards
Every transaction triggers complex encryption, real-time bank verification, and fraud detection — all within seconds. What looks like a simple piece of plastic is actually a self-contained security system working silently in your wallet.
