N2 Elite

N2 Elite is sold as a game cheating product, called previously Amiiqo, an name probably too close to the original targeted game Amiibo.
I'm not interested at all in its gaming aspects but it's primarily a (multiple) NTAG215 emulator and in that respect, I'm very curious about that product :)

Intro

It's a small round passive device with one button. It can emulate up to 200 NTAG215 and can be programmed via an Android app or, if you buy their additional reader, via a PC application: N2 Manager for Windows or Mac.

Credits: I heard about it by reading a 3-page article of Patrick Gueulle in the French revue Le Virus Informatique #28. In that article, the author revealed how the emulator could be used to emulate any 7-byte UID or even a 4-byte UID (we'll come to that later) and he's providing two programs written in Basic; apparently Patrick remained true to himself ;)

• Official

Official site has a list of shops. Mine came from Cyprus (Playmods.co.uk) and was delivered in 4 days to Belgium.

• NTAG213/215/216 datasheet

Hardware

Device was sold previously under the name Amiiqo, and they insist this is the same hardware as the N2 Elite. Nevertheless there are apparently two revisions of the product:

• V1, preloaded with 10 amiibo figurines
• V2, empty, and an alien face printed on the PCB

I got a V2.

Patrick Gueulle mentions the QFN24 chip has a mark "SX3" but mine is completely black. Under the microscope he found two references on the die: "G4830H001I" and "DI 503 03".

Traces

Let's trace some transactions between the Android app and the device.
