In this setup, how do PED devices connect to the register?

• A. They connect directly to the register
• B. They do not connect directly to the register
• C. They connect via a separate box
• D. They connect through the network switch

Answer: (B)

PED devices are kept separate from the register to protect sensitive card data. In practice, the PIN entry device handles the card data and PIN, encrypts it, and then communicates with a payment processor or through a dedicated payment terminal/Gateway. The register itself just passes the transaction to that processor, not handling the card data directly. So the setup is that PEDs do not connect straight to the register; they connect via a separate box or through the payment network to the processor, ensuring a secure, PCI-compliant path.
