## Why

NFC integrations fail easily because of subtle differences between card types, terminal hardware, and operating systems. Clear guidance reduces integration errors and support load.

## What

Developers build four request types: identify, read, write, and session. Each has card-specific data structures. Adyen terminals run two operating systems that do not always have feature parity.

## How

I structured the documentation around user intent instead of API shape. Using existing CMS components, I organized the page so developers could quickly find the right combination of card type, terminal type, and request type.

## Result

The documentation reduced cognitive load in a complex integration flow with a high potential for implementation errors.
