Which term describes a service that authorizes a user's transfer of funds between financial institutions to sellers without direct delivery of either bank or credit card info (for example, Apple Pay)?

• A. Aquirer
• B. Issuer
• C. Processor
• D. Gateway

Answer: (D)

The service being described is a gateway—the secure channel that lets a merchant transfer payment data to the rest of the network without exposing actual bank or card numbers. When a payment is made with something like Apple Pay, the wallet provides a token instead of the real card details. The gateway takes that token, passes it to the payment processor and network, and this flow leads to an authorization request sent to the card issuer. The result (approved or declined) is then returned to the merchant through the same secure path, and settlement happens later between the acquiring bank and the issuer.

This is different from the other roles: the acquirer is the merchant’s bank account that processes and settles funds; the issuer is the customer’s card-issuing bank; the processor is the technology that routes data between the gateway, acquirer, and issuer and handles the transaction data itself. The gateway’s job is specifically to securely transmit and coordinate the payment data—often in tokenized form—without ever exposing sensitive card information.
