The NFP library is for reading and writing NFP tags (IC tags formatted for NFP) using the NFC (Near Field Communication) Reader/Writer for CTR or the built-in NFC module on the SNAKE system.
The NFP library currently supports the following features.
Feature | Comments |
---|---|
NFC Tag Detection |
The NFC Reader/Writer can detect amiibo, and SNAKE can detect amiibo and transport system IC cards (Suica, PASMO, Kitaca, TOICA, manaca, ICOCA, SUGOCA, nimoca, HAYAKAKEN). This documentation refers to all detectable IC tags and cards as NFC tags. NFC tags other than those listed above may also be detected, but there is no guarantee that the NFP library will operate. |
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. |
No more than one tag can be used at a time. Recognition of two or more tags at the same time is not supported and results in abnormal operation. Attempting to use the NFC Reader/Writer in this way may cause the NFC Reader/Writer to stop responding, and you will have to power-cycle the system.
