PAM Native NFC

Terminal window
pam add nfc
pam doctor
$nfc->beginRead(fn (bool $ok, ?string $error) => null);
$nfc->write(NdefRecord::uri('https://pam.dev'), fn (bool $ok, ?string $error) => null);
$nfc->poll(fn (array $events) => handleNfcEvents($events));

Nfc begins/ends sessions, writes, and polls; NdefRecord builds URI, text, MIME, and external records; NfcEvent/NfcEventKind type events; NfcAvailability reports support.

Only one session may run. The queue holds 128 events and PHP NDEF payloads stop at 1 MiB; physical tag capacity is checked on write. iOS requires capability and signed compatible hardware; Android requires a foreground Activity. End sessions when their screen leaves foreground and treat all tag data as untrusted.

NfcPluginProvider registers the native session module.
