No, same technology. S2C was there *before* NFC-WI was standardized. So NFC-WI is "inspired" by S2C. I didn't find any difference between the two so far. > So having the NFC controller, e.g. Samsung S3FHRN2 > (http://www.samsung.com/global/business/semiconductor/support/ > brochures/downloads/systemlsi/S3FHRN2.pdf), which declared the NFC-WI > support we are talking about 2 different, probably not compatible > solutions?

I'm very sure that this NFC controller has card emulation capabilities even without a dedicate SE chip. Emulation of the low-level protocol (up to ISO 14443-4) is handled by the PN532 and the high-level APDU protocol (ISO 7816-4) is handled by the application processor. > NXP delivers to Samsung, SonyEricssion, Nokia, etc. the S2C might be > pretty widespread, right? At least everything that uses a SmartMX as secure element uses the S2C/NFC-WI. > But since S2C is NXP proprietary do you know if other NFC IC > manufacturers are going to support NFC-WI?
