Credit card fraud is the unauthorized use of a payment card or its credentials to make purchases or withdraw funds. In ecommerce it overwhelmingly takes the form of card not present fraud: the bad actor never holds the physical card, only stolen details used at checkout without the cardholder’s knowledge or consent.
The Main Types of Credit Card Fraud
Card not present fraud covers online, phone, and mail-order transactions on stolen credentials, and it is the dominant form facing ecommerce brands. Card present fraud uses counterfeit or stolen physical cards, fed by card skimming. Application fraud opens new card accounts using stolen or synthetic identities. And account takeover turns a legitimate customer’s stored payment methods into the fraudster’s checkout. Upstream of all of them sits card testing fraud, where stolen numbers are validated through small transactions before the real spending starts.
How Stolen Card Data Reaches Your Checkout
Card credentials are harvested through data breaches, phishing and its text and voice variants, skimming devices, and malware, then sold in bulk on the dark web. By the time a stolen card hits an ecommerce checkout, it has usually been tested, priced, and resold. Consumer reports aggregated through the Federal Trade Commission’s fraud reporting portal consistently rank credit card fraud among the most reported fraud types.
Who Pays for Credit Card Fraud
Cardholders are largely protected: consumer liability for unauthorized charges is capped and usually waived. For card not present transactions, the loss lands on the merchant. The cardholder disputes the charge, the issuer files the chargeback, and the business loses the merchandise, the revenue, and a dispute fee. That liability split is why fraud screening is a merchant investment rather than a bank one, and why every stolen-card order that ships becomes a chargeback weeks later.
How to Prevent Credit Card Fraud as a Merchant
Layered screening beats any single check: AVS and CVV as signals, velocity checks against card testing, device intelligence and behavioral analysis to spot a buyer who doesn’t match the cardholder, and screening tuned so that stopping fraud doesn’t mean turning away good customers as false declines.

Frequently Asked Questions
Is credit card fraud the same as identity theft?
Credit card fraud is one common outcome of identity theft, but identity theft is broader, covering any unauthorized use of personal information, from opening accounts to filing false claims.
Why did credit card fraud move online?
Chip cards made counterfeiting physical cards far harder, so fraud followed the path of least resistance to card not present channels, where possession of the physical card is never checked.
