Android implementation of NfcReadManager. Handles NFC tag scanning using the Android NFC Adapter in Reader Mode.

internal expect class NfcReadManager(config: NfcConfig)

Manager class for handling NFC reading operations.

internal actual class NfcReadManager(config: NfcConfig) : NSObject, NFCTagReaderSessionDelegateProtocol

iOS implementation of NfcReadManager. Handles NFC tag scanning using CoreNFC's NFCTagReaderSession. The system manages the scanning UI; RegisterManager is a no-op.

NfcReadManagerState

interface NfcReadManagerState

Interface defining the state and operations for the NFC reader.

NfcReadManagerStateImpl

internal class NfcReadManagerStateImpl(config: NfcConfig) : NfcReadManagerState

Concrete implementation of NfcReadManagerState.

Properties

NFC_URI_PREFIXES

internal val NFC_URI_PREFIXES: Array<String>

NFC Forum URI identifier codes used to expand the first byte of a Well-Known URI NDEF record into its full URI prefix string.

Functions

extractUid

internal fun extractUid(tag: NFCTagProtocol): String

Extracts the UID from an NFCTagProtocol, formatted as an uppercase hex string with ":" byte separators (e.g. "04:1A:2B:3C").

getFriendlyName

internal fun getFriendlyName(tech: String): String

Maps a fully-qualified Android NFC technology class name to a user-friendly label.
