Which statement best describes the use of a PCI-compliant card reader in processing payments?

• A. To securely accept credit card payments and capture authorization.
• B. To scan barcodes for case indexing.
• C. To print receipts.
• D. To manage payroll.

Answer: (A)

The main idea here is secure payment processing with a PCI-compliant card reader. These devices are designed to read card data and transmit it through encrypted channels to a payment processor, so the authorization from the card issuer can be requested and captured safely. This protects sensitive cardholder information and helps meet PCI-DSS requirements, reducing the risk of data theft during a transaction. The other tasks described—scanning barcodes for indexing, printing receipts, or managing payroll—aren’t part of secure payment processing, so they don’t describe what a PCI-compliant card reader is used for.
