The NFP library is for reading and writing NFP tags using the external near-field communication (NFC) reader/writer for 3DS or the built-in NFC module on the new Nintendo 3DS.
The NFP library currently supports the following features.
Feature | Comments |
---|---|
NFC Tag Detection | Any IC tag or IC card that supports the NFC IP-2 standard (NFC-A/B/F or ISO 15693) can be detected. This documentation refers to all detectable IC tags and cards as NFC tags. |
Reading and Writing NFP Tags | The library can read from and write to NFP tags only. |
Backing Up NFP Tags |
When an application writes data to an NFP tag using the NFP library, the library automatically backs up the data to the system (under save data in the amiibo Settings application). If the data on the NFP tag ever becomes corrupted, the application can explicitly restore the data on the NFP tag using the backup. |
