Straw Man?
I haven't heard the phrase "wallet-less future" before for, I think, the obvious reasons mentioned in the article: "We will likely still require identification for driving a car, boarding an airplane, and getting our frequent traveler points when checking in at the hotel."
None of that means the future for mobile payments is dim, however. While I wouldn't want to give my phone to a server at my favorite watering hole to pay my bill, I certainly don't mind hitting the funds transfer button at the check out counter of my local coffee shop. The wallet will be necessary until we begin embedding identity chips in our bodies, and until then we can enjoy other alternative payment methods.
