Someyears ago I wrote an article pointing out that NFC ought to be safer than QR codes because NFC included a standard for digitally-signing tags (although I did also note that no-one used it) whereas anyone could easily create bogus QR codes.
Well, I might not go so far as to call [QR codes] evil, but they certainly have the potential to enable person or persons unknown to act with evil intent.
I said at the time that you could “imagine a situation in which a powerful player like Apple, using Passbook, forces a scheme for digitally-signing QR codes and sets up a structure for key and certificate management”. I also suggested, in connection with a couple of project we were working on at the time, that the mobile operators do the same. But none of this happened, and QR codes became popular precisely because any app could read them. Now I read in the South China Morning Post that in March 2017 some 90m Yuan were stolen via QR code scams in Guangdong alone (a suspect in the case replaced merchants legitimate bar codes with fake ones that embedded a virus to steal personal information) and that in China, a quarter of viruses and trojans come in via QR.
Even the man who invented QR codes says that they are an interim technology.
While I have no inside information on the subject, I do expect a future iPhone (and, for that matter, iPad) to have NFC. NFC is a convenience technology, and Apple loves convenience
I noted some surveys that showed that NFC generated better results for merchants, but only once consumers could get it working. As my good friend Osama Bedier, then head of Google Wallet, pointed out at that time, this is was some barrier because of the amount of “futz” it took to get NFC working.
