From the article. "A great part of discussion in comments on the original thread I've made was about soldiers on the battlefield and a heavy usage of devices close to the line of contact. Android users might turn off Wi-Fi and Bluetooth and even remove their SIM card, thinking they’ve minimized their radio footprint. But NFC often remains active by default — and since most people assume it only matters within arm’s reach, they don’t bother disabling it."

I would think a faraday bag would be far more efficient for this - should take care of the NFC issue too
