Now that we have figured out where CVC or CVV is on a bank card, we will tell you how to use them correctly. When purchasing goods and services online, the system in most cases redirects the user to the payment page (a third-party payment system or the online form of the store itself). In order for the funds to be successfully transferred to the seller's account, you must enter the card details: its 16-digit number, expiration date, and the CVC/CVV code. Some banks use an additional security tool - a numeric or alphabetic password. It is sent to the client in an SMS message or PUSH notification, and it is simply impossible to complete the payment transaction without entering it in a special field.
Do payment systems always ask for CVC or CVV?
Despite the fact that such codes are the best way to protect against fraudulent transactions on the Internet, sometimes sellers do not require buyers to enter them when making transactions. In this case, the already mentioned one-time alphanumeric passwords sent to the buyer's mobile phone are used as a guarantee of security. Theoretically, it is also possible to pay only by card details (number and expiration date), but such financial transactions on the Internet are rare due to their insufficient security for cardholders.
Where and to whom can you communicate codes: all about card security
The first and most important rule is that the three-digit code czech republic mobile database on the back of the plastic card should never be given or communicated to strangers, no matter who they claim to be. Any attempt to find out your CVV in a telephone conversation with a “bank employee” or “mobile operator” (who are 100% likely to be ordinary scammers) is fraught with loss of money. Also, under no circumstances should you upload a photo of the back of your plastic card to websites or forward it to anyone.
However, the mentioned security measures concern not only CVC, but also other details, since in some cases, attackers are able to withdraw money from a credit card or salary card, knowing only its number and expiration date. If you need to upload a scan of the card somewhere, be sure to use a graphic editor and retouch all the digits of the 16-digit number, except for the first and last four characters.
There is no point in reminding you once again that you can enter details or upload a photo of the front (but never the back) side of the card only on trusted websites. In order to avoid unpleasant situations and protect yourself from so-called phishing websites, always check the name of the store or online service in the payment form before confirming the transaction. We also recommend using a secure https Internet connection and paying for purchases exclusively from your computer or smartphone.
What to do if you have lost your plastic card, because in this case, it is highly likely that criminals will gain access to its details and CVC/CVV? If you find yourself in such an unpleasant situation, immediately contact the bank office or its employees by phone, block the card account and apply for a reissue.
