It is illegal. It differs from a normal declined payment. A merchant may see many attempts across a short period, many card numbers, or many failed checks. The goal is to separate valid card data from invalid data. Card testing raises chargebacks, fees, and processing risk. Buying or selling CVV data is also illegal.
Each failed attempt can add fees. Successful fraudulent orders can lead to chargebacks and lost inventory. A pattern of fraud can affect a merchant account. Acquirers and card networks monitor fraud rates. High fraud rates can lead to reserves or account closure.
Credit card testing is fraud. It can violate computer fraud laws, payment network rules, and cardholder data rules. Buying, selling, or possessing card data without authorization is illegal in the US and other countries. Merchants should report suspected testing to their acquirer and processor.
Document the attempts. Keep authorization logs. Contact the acquirer and processor. Review access controls. Update fraud rules. Notify law enforcement when required. Do not confront suspects.
