Fraud
With the growth of credit and debit card usage and rising e-commerce transaction volumes, there has been a serious increase in exploiting user negligence to harm customers. Fraud means using someone else's card at a merchant or ATM to gain unjust profit.
Security
Fraud means obtaining unjust gain by carrying out a transaction at a merchant or ATM using someone else's credit card or debit card, causing a loss to the real cardholder, the merchant, or the bank. So what fraud codes do Visa and Mastercard use?
Fraud
Fraud controls fall into two main types: application fraud controls, which check card and merchant applications, and transaction fraud controls, which monitor card and POS transactions.
Credit Card
CNP refers to a transaction made through a website or a company's own app payment page, where the card is not read by any device and its details are entered manually. It is short for Card Not Present.
Chargeback
A chargeback is the process of requesting that an amount paid by credit card be refunded, either because the goods or services paid for were not received, or because a transaction is identified as one the cardholder did not carry out.
Credit Card
It is a CVV2/CVC2 code that changes every few minutes instead of the static code printed on the back of a credit card, aimed at reducing fraud risk in CNP (Card Not Present) transactions.
Payment Systems
The Address Verification Service (AVS) is a fraud prevention system that, when used effectively, can help limit fraud and chargebacks. This post lists the AVS response codes used by AMEX, Mastercard and Visa, with a description of each.
Merchant & POS
Address Verification Service (AVS) is a fraud prevention system that helps limit fraud and chargebacks when used effectively. It verifies that the address a customer enters matches the cardholder's address on file with the issuer.
Credit Card
Credit card fraud is generally committed using the card itself, using card details without the card, via excess or duplicate withdrawals, or by seizing identity information. ATM card trapping is common, since ATMs hold the card during the transaction.
Payment Systems
Every payment transaction completes in seconds, yet dozens of controls run behind the scenes. This post covers the precautions for authorization and clearing, the critical role of reversals, and the financial loss scenarios most often seen in the field.
