Which of the following is an example of a card issuer?

A card issuer is a financial institution that provides credit or debit cards to consumers and is responsible for managing accounts associated with these cards. This includes processing transactions, extending credit, and handling customer service related to card usage.

In this context, Chase is a bank that issues credit and debit cards to consumers. Through their credit card offerings, they provide customers with lines of credit, manage billing, and offer customer support, making them a prime example of a card issuer.

The other entities mentioned play different roles in the payments ecosystem. Amazon is primarily a retailer and does not issue cards but does offer co-branded credit cards through partnerships. Visa acts as a payment network or brand which facilitates transactions between issuers and merchants but does not issue cards itself. First Data, now part of Fiserv, is a payment processor that provides services to merchants and banks but does not issue cards directly to consumers. Therefore, Chase stands out as the correct answer as it directly engages in the practice of issuing payment cards to consumers.
