    This reads pretty much misleading to me.

    They say the flipper could bomb phones within 30 ft range. Via NFC! I would even doubt them stating a range of 30 mm.

      That attack is via bluetooth, not NFC. And the article states exactly that (just checked).

      It mostly depends of the antenna setup.

      I’m fairly sure you can get several meters of range with an external antenna.

        I think a meter is pretty much the limit with most NFC. There is a longer range NFC+ that can reach further, but nowhere near 30ft.

          Long range stuff typically is UHF RFID in the 860-960MHz band.

          HF NFC at 13.56 MHz can be done up to roughly 20cm, though with passive sniffing you might pick up parts at longer range.

          LF NFC is just a mess. I think there were some pretty long range readers available, but nobody should be using that stuff anymore, it’s just horrible. Unfortunately there still are companies using that for access control, so I’m now and then handing out copies of their keys to friends. The main security on those things is that sometimes it takes a few tries to get the your reader detect the tag.
