This is used by the [[amiibo Settings]] applet. This service has the above commands, in addition to the command-set listed below.

There are two different revisions of the NFC module. First version was introduced on New3DS only with firmware 8.1.0-0_New3DS. Second version made its appearance with 9.3.0-X, on both Old3DS and New3DS.
There are at least two different revisions of the NFC module. First version was introduced on New3DS only with firmware [[8.1.0-0_New3DS]]. Second version made its appearance with [[9.3.0-21|9.3.0-X]], on both Old3DS and New3DS.
These two versions are not interchangeable and not compatible, since the newer version uses a different command set and has no implemented commands from the older version. This does not introduce compatibility problems since no retail software used the NFC module before the Super Smash Bros for 3DS, whose NFC update required 9.3.0-21.
