GetStateOld

No input, returns an output u32.

IsNfcEnabledOld

No input, returns an output bool.

This runs the same code as #IsNfcEnabled.

GetState

No input, returns an output u32.

This replaces #GetStateOld.

IsNfcEnabled

No input, returns an output bool.

This replaces #IsNfcEnabledOld.

nfc:sys

SetNfcEnabled

Takes an input bool, no output.

OutputTestWave

Takes an input bool and a #TestWaveType, no output.

ReadMifare

Takes an input #DeviceHandle, a type-0x6 output buffer containing an array of #MifareReadBlockData, a type-0x5 input buffer containing an array of #MifareReadBlockParameter, no output.

sdknso passes the same user-specified array-count for both buffers.

WriteMifare

Takes an input #DeviceHandle, a type-0x5 input buffer containing an array of #MifareWriteBlockParameter, no output.

SendCommandByPassThrough

Takes an input #DeviceHandle, a nn::TimeSpan, a type-0x6 output buffer, a type-0x5 input buffer, returns an output u32 out_size.

sdknso copies the output u32 into an u64. This is the actual size which was copied into the output buffer.

This allows using a raw NFC command. The input buffer contains the command data (id + params), and the output buffer contains the response.

KeepPassThroughSession

Takes an input #DeviceHandle, no output.

ReleasePassThroughSession

Takes an input #DeviceHandle, no output.

nfp:user

This is "nn::nfp::detail::IUserManager".

Initialize

Takes a PID, an AppletResourceUserId, an u64, a type-0x5 input buffer containing an array of #RequiredMcuVersionData, no output.

sdknso passes value 0 for the u64.

Internally this is mostly the same for each service, this differs depending on the service/cmd however.

Finalize

No input/output.

RequiredMcuVersionData

In sdknso, the global data containing the array data for this is "nn::nfc::client::RequiredMcuVersionData". The array entry is 0x20-bytes.

DeviceHandle

This is "nn::nfc::DeviceHandle". This is a 8-byte struct with 4-byte alignment.

TestWaveType

This is u32 enum "nn::nfc::TestWaveType".

MifareReadBlockData

This is "nn::nfc::MifareReadBlockData". This is a 0x18-byte struct.

MifareReadBlockParameter

This is "nn::nfc::MifareReadBlockParameter". This is a 0x18-byte struct.

MifareWriteBlockParameter

This is "nn::nfc::MifareWriteBlockParameter". This is a 0x28-byte struct.

RomFS

[9.0.0+] The nfc-sysmodule RomFS contains:

 ST21NFCD_01_05_6811.bin

These are firmware files for the NFC IC inside Switch Lite units.

Application IDs

Application IDs (also referenced as "access_id" in official software) are game-unique u32s used to access the amiibo 0xd8-big application area.
