[Mobile Payments] Change CardReaderService to make it clear we only support one connected reader #8683
Description
@toupper:
Technically this means that if any of the connected readers is the Apple Built-in one we don't show the view right? What happens if we are connected to a Bluetooth reader apart from of that?@joshheald:
Correct, however we don't actually support being connected to more than one reader, and neither do Stripe.So we can't be connected to more than one at a time, and this class doesn't otherwise handle that situation anyway (it relies on .first to determine the connected reader.)
The proper fix for this inconsistency would be to change connectedReaders to a single object, not an array, but that is way out of scope here 😊
