Surely you have already met with the concept of CVC / CVV codes when paying on the Internet. In this article, we will look at what is a CVC / CVV code on a bank card and what is it for? Let’s talk about how the security of online payments is carried out.
What is CVC / CVV code on a bank card
CVC/CVV («Card Validation Code»/»Card Verification Value») is a special verification number for the authenticity of a bank card when paying online via the Internet.
You can view CVC/CVV on the back of your bank card. Rarely, but it happens that it is indicated in front. Russian banks do not issue such cards, so always look for the code on the back.
The main task of this code is additional authentication of the card.
Most often, we come across the concept of CVV / CVC when paying on the Internet. The payment must include:
- Card number;
- Surname and name of the holder;
- end date;
- Code sent via SMS;
It is more correct to write CVC2 / CVV2, since these codes are available to us for input. The CVV/CVC numbers are invisible and embedded into the tape.
The CVV2/CVC2 code may not be on the card at all. This means that either it was erased, or using such a card it is impossible to pay for purchases via the Internet. This should be obtained from the bank that issued the card.
Different sites call CVC / CVV codes differently:
- Authentication code;
- Security code;
- Personal security code;
Difference between CVV and CVC
VISA payment system uses CVV, MasterCard — CVC. In fact, this is the same thing, it’s just that different systems are called differently.
There are also other codes:
- CVN and CVN2 (Card Validation Number, Chinese standard China UnionPay);
- CID (Card Identification Number, American standards American Express and Discover: four digits on the front side);
- CSC (Card Security Code, American Express international standard: three digits on the reverse side);
- CVD (Card Verication Data, international Discover standard: three digits on the reverse side);
