All You Need to Know About Credit Card Fraud. Such costs include, among other expenses, the refunds that banks and credit card companies make to defrauded clients (many banks in the West cap consumers’ liability at US$50 as long as the crime is reported within 30 days for credit cards and within two days for debit cards. But there are two main categories: card-not-present (CNP) frauds: This, the most common kind of fraud, occurs when the cardholder’s information is stolen and used illegally without the physical presence of the card. This kind of fraud usually occurs online, and may be the result of so-called “phishing” emails sent by fraudsters impersonating credible institutions to steal personal or financial information via a contaminated link. Once that data is used to make a purchase, the consumer’s account is charged. The mechanism of a credit card transaction Credit card fraud is facilitated, in part, because credit card transactions are a simple, two-step process: authorisation and settlement. At the beginning, those involved in the transaction (customer, card issuer, merchant and merchant’s bank) send and receive information to authorise or reject a given purchase. Once a purchase had been authorised, there is no going back. Then, the card issuer physically delivers the credit card to the consumer. To make a purchase with it, the cardholder gives his card to the vendor (or, online, manually enters the card information), who forwards data on the consumer and the desired purchase to the merchant’s bank.

If you are the owner of a credit or a debit card, there is a non-negligible chance that you may be subject to fraud, like millions of other people around the world.

Starting in the 1980s, there has been an impressive increase in the use of credit, debit and pre-paid cards internationally. According to an October 2016 Nilson Report, in 2015 more than US$31 trillion were generated worldwide by these payment systems, up 7.3% from 2014.

In 2015, seven in eight purchases in Europe were made electronically.

Thanks to new online money-transfer systems, such as Paypal, and the spread of e-commerce around the world – including, increasingly, in the developing world – which was slow to adopt online payments – these trends are expected to continue.

Thanks to leading companies such as Flipkart, Snapdeal and Amazon India (which together had 80% of the Indian e-commerce market share in 2015) as well as Alibaba and JingDong (which had upwards of 70% of the Chinese market in 2016), electronic payments are reaching massive new consumer populations.

This is a goldmine for cybercriminals. According to the Nilson Report, worldwide losses from card fraud rose to US$21 billion in 2015, up from about US$8 billion in 2010. By 2020, that number is expected to reach US$31 billion.

Such costs include, among other expenses, the refunds that banks and credit card companies make to defrauded clients (many banks in the West cap consumers’ liability at US$50 as long as the crime is reported within 30 days for credit cards and within two days for debit cards. This incentivises banks to make significant investments in anti-fraud technologies.

Cybercrime costs vendors in other ways too. They are charged with providing customers with a high standard of security. If they are negligent in this duty, credit card companies may charge them the cost of reimbursing a fraud.

The types of frauds

There are many kinds of credit card fraud, and they change so frequently as new technologies enable novel cybercrimes that it’s nearly impossible to list them all.
