supportedCardEntryMethods

Set of card entry methods this reader can support. At a given time, a reader might not be able to use all the "supported" payment methods. In particular, for a CardEntryMethod.CONTACTLESS the contactless NFC field will time out a while after a payment begins, and after that a contactless tap will not work, even though contactless payments are supported by the reader. Because these changes to the available payment methods happen in the context of a payment, they are reported through the com.squareup.sdk.mobilepayments.payment.PaymentManager instead. See CardEntryMethod for possible entry values.
