If you are using CocoaPods, update your Podfile:

pod 'StripeTerminal', '1.3.0'

1.3.0 2020-07-28

This update adds Verifone P400 support for the following methods in StripeTerminal:

• setReaderDisplay and clearReaderDisplay allow you to set the Verifone P400’s cart details interface
• readReusableCard (only available for US merchants)

This update also introduces a cosmetic change to SCPReader.deviceSoftwareVersion. The Key Identifier number was previously displayed as the five-character string 30000 . This and future updates will display the identifier as a six-character string: 300001. The key itself has not changed.

Not every Stripe Terminal reader supports all the functionality in the SDK. If you call a function that is not supported by the currently connected reader you will receive a SCPErrorFeatureNotAvailableWithConnectedReader error.
