Question

A recreation-fee system replaces stored cardholder numbers with tokens for processing, and the cashier screen shows only the last four PAN digits. Which statement best contrasts those techniques?

Accepted Answer

Tokenization substitutes a non-sensitive token in systems of record, while masking hides digits in displays without being the same as encryption. — Tokenization swaps the real card number for a stand-in chip in the back-end systems; masking is the black marker on the screen that leaves only 1234. Neither one is 'encrypt the whole laptop disk,' and masking alone is not a crypto lockbox.

Answer

Masking permanently destroys the original PAN in the payment processor so refunds become impossible.

Answer

Tokenization and masking are both forms of full-disk encryption applied to the cashier workstation.

Answer

Masking creates a reversible public-key ciphertext of the PAN that any kiosk can decrypt offline.
