NFC cover will be the deciding factor on whether I’ll hold on to my FP2. I love many features of it, but the lack of NFC will eventually drive me away. I seriously hate that my employer-provided-POS-samsung works with the (NFC-based) public transportation of my home town, and my FP2 doesn’t. Some NFC solutions have been proposed here on the forum, but their goals seem rather over-the-top for my purposes. I just need NFC.
Since my time is rather limited at the moment, I thought I’d better ask here first for any apparent pitfalls or prior knowledge. Do you know about possible troubles I’ll run into if I try to interface NXP’s NFC controller PN533  to FP2 back port (PN533 has a USB interface)? Would I need to create drivers for PN533? The drivers might already be present in the android kernel  (I’m not a kernel-developer), and adafruit has neat NFC schematics for the sister-chip (PN532) that may prove useful .
