I'd love to see NFC become more widespread for all the benefits outlined in the article. However, my wife commented that if one of NFC's main benefits as a digital wallet is to "allow me to have my 30+ cards all stored in my NFC phone", wouldn't it be easier for card companies to band together to enable a combined plastic card? I had to admit that I didn't have a good response for her. My initial reaction was to cite the flexibility of NFC, despite how nascent it is compared to the proliferation of loyalty & credit cards, but she demolished me by stating that she would much rather prefer to carry one plastic card vs. buying a new phone. Unless NFC becomes as dead simple as swiping plastic cards (notwithstanding the incumbency of ingrained swipe'n'sign habits), widespread adoption may be more of a challenge than optimists such as the author and me would like to believe.
