What Is CVV, Expiry Date & OTP? A Beginner’s Guide to Card Security
In today’s digital world, debit and credit cards are used almost everywhere—from buying groceries to shopping online. But with this convenience comes risk. Cyber fraud, card cloning, and phishing attacks are real. To protect yourself, you must understand the core security features of your card: CVV, expiry date, and OTP.
What Is a CVV?
CVV stands for Card Verification Value. It’s a 3-digit (Visa, MasterCard) or 4-digit (AMEX) number on your card. It helps verify that you physically have the card during online or phone transactions.
- For Visa/MasterCard: Found on the back of the card
- For AMEX: Found on the front of the card
Tip: Never share your CVV with anyone. Banks never ask for it.
What Is the Expiry Date?
Your card’s expiry date (MM/YY format) tells you when the card will no longer be valid. After this date, your card won’t work, even if money is available in your account. You’ll usually receive a replacement card before it expires.
Why Is the Expiry Date Important?
- Used in card authentication during online payments
- Helps prevent misuse of old cards
- Linked to card security and auto-renewal processes
What Is an OTP?
OTP stands for One-Time Password. It’s a 4 to 8-digit code sent to your registered mobile number/email to verify transactions. You’ll see OTPs when you:
- Make online purchases
- Change passwords or PINs
- Login to banking apps from a new device
OTPs are valid for a few minutes and can only be used once. They are a crucial layer of card security.
Card Security Tips for Beginners
- Never share your OTP, CVV, or expiry date over phone/email.
- Use banking apps with fingerprint/face lock.
- Enable transaction alerts via SMS/email.
- Deactivate international usage if you don’t need it.
- Use a virtual debit card for online shopping.
What to Do If You Suspect Card Fraud
If you believe your card details have been compromised, take these steps immediately:
- Block your card using the bank app or helpline
- Report to your bank’s fraud department
- File a complaint on cybercrime.gov.in (India)
Final Words
Understanding what CVV, expiry date, and OTP mean can help protect your money. In 2025, as digital payments dominate, card security is more important than ever. Be alert, stay informed, and don’t let scammers win!
