For showing saved payment options to users, what type of data page is used?

Using a non-keyed data page for displaying saved payment options to users is appropriate because it allows the data to be sourced without needing a unique key to fetch specific instances of data. Non-keyed data pages can fetch multiple instances of data, such as a list of saved payment methods, enabling the system to present all options to the user in a user-friendly manner.

This type of data page can be especially beneficial in scenarios where the data context may vary or when the same page needs to be accessed by multiple users without specific identifiers. Since saved payment options are typically not meant to be uniquely filtered but rather displayed collectively, a non-keyed data page supports this use case effectively.

Keyed data pages, in contrast, require a unique identifier for fetching data and would not suit the need for displaying multiple saved options. Temporary data pages are meant for short-lived data that is not intended to be persisted, while static data pages serve data that does not change frequently, which might not be appropriate for the dynamic nature of saved payment options.
