In banking, CSC stands for Card Security Code. This code is a crucial security feature for debit and credit cards.
Understanding the Card Security Code
The Card Security Code (CSC) is a three- or four-digit number that is not embossed on the card like the main card number. This extra layer of security helps prevent fraud in online and phone transactions. The CSC helps verify that the person using the card is in possession of the physical card.
Alternative Names for CSC
The CSC is also known by several other names, all referring to the same security feature:
- CVV2 (Card Verification Value 2): Commonly used by Visa.
- CVC2 (Card Validation Code 2): Typically associated with MasterCard.
- CVV (Card Verification Value): A general term applicable to various card networks.
Where to Find Your CSC
The CSC is usually located:
- On the back of most cards: Near the signature panel, you will find either a three- or four-digit code.
- Visa and Mastercard: Typically have a three-digit CSC.
- American Express: Generally uses a four-digit code on the front of the card.
How CSC Protects Your Card
- Online and Phone Transactions: When making purchases online or over the phone, you are usually required to enter your CSC. This verifies that you have physical possession of the card, making it harder for fraudsters who may have stolen just your card number.
- Reduced Risk of Fraud: The lack of embossing makes the CSC more difficult for criminals to obtain. Even if a card number is compromised, the CSC is often not stored in merchant databases, providing an additional safeguard.
- Not Stored By Retailers: Reputable online retailers and service providers will not store your CSC, further enhancing your card's security.
Example of CSC Use
Imagine you're making an online purchase. Besides your card number and expiration date, you will be asked for your CSC. This final step confirms that you have the card in your possession, decreasing the possibility of unauthorized use.
