Is it possible to add the NFC to the phone which does not have it? My phone is a Motorola Moto 2g LTE (xt1072). It is really good phone but there is a one problem, it does not have NFC. Is there any solution, to add NFC to the phone which does not have it – and would Android be able to use it then? If yes to both, could you provide some links to such existing "equipment" as proof that it's not only "a nice theory"?
Sorry to say this, but it seems to be a long way off before truly turning a NON NFC into NFC phone (as pointed out by Izzy in comments, there have been some efforts but no progress)


NFC SD and SIM Cards claims that Both SIM and SD cards can be equipped with NFC chips can be used to enable. 
Toshiba has come up with NFC SD card last year, but the catch is that it requires NFC enabled device to work with. All it does , is enabling seeing the contents of SD card without physical connection
NFC-enabled SIM cards launched a couple of months back in Singapore for paying for rail travel- but they work only with NFC enabled phones
