Card testing, or carding, is when fraud actors use stolen credit card details for small transactions, verifying which cards are active or have stored value. Verified cards can then be used to make high-dollar fraudulent purchases—or exposed and sold on the dark web. Ultimately, businesses suffer the financial impact of fraud-driven chargebacks, lost revenue, and unauthorized transaction fees.
