Looks like this is missing the data collector as well

Suggested change

	- [AMEX](https://developer.paypal.com/braintree/articles/au/transactions/accepted-payment-methods#american-express)
	- [American Express](https://developer.paypal.com/braintree/articles/au/transactions/accepted-payment-methods#american-express)

[stechiu]

Curious if this change is necessary or a preference? I think AMEX is fine

[jaxdesmarais]

We do not call it AMEX in the SDK or anywhere in the dev docs, so it's important to align the naming here with what we publicly advertise as the product name.

[stechiu]

I'll make the change but we do use both Amex and American Express in both the SDK and the dev docs

[jaxdesmarais]

Since we call the module by the full name, we should use that here for consistency across the product: https://github.com/braintree/braintree_ios/tree/main/Sources/BraintreeAmericanExpress

Curious why data collector should be listed as a payment method? It would be it's own separate section. I know it's one of the BT integrations but the definition and purpose of it is "DataCollector is used to collect device information to aid in fraud detection and prevention." which is why I didn't include it.

That's a good call! Since we want this to represent all features and have added Shopper Insights in this PR we should rename the header from Supported Payment Methods to Supported Payment Methods and Features so we can also add the data collector. The goal is to list everything we offer in the README where we have dev docs and aren't deprecated. This will give merchants and developers one place to see everything we offer!
