"I think google wallet, square, and other RFID/NFC technologies are thinking about the future... The problem with these technologies is vendor adoption. It’s not here yet, but it’s on the way."

The author is incredibly underestimating the difficulty of driving vendor adoption of a new payment system.

Google just spent years and enormous amounts of money trying to drive vendor adoption of Wallet, and has more or less given up on the NFC part.

Square's achieved the most so far, but only by bundling it with its POS & processing service, which not all vendors are going to switch to (or even if they took over the POS world it would take a decade).

Considering that's the crux of his argument, it's entirely unsupported.
