Without comment on this specific article, there was a video of this doing the rounds last year using a FLIR ONE on a card terminal. I subsequently saw another video debunking it. It only worked if you super cooled the pin pad, there was evidence of that in the original video; it was totally un-workable with a normal room temperature keypad. I imagine though it's likely highly variable though depending on the thermal conductivity and emissivity of the surface being touched, as well as the actual room temperature and the quality of the thermal sensor. EDIT: This random video seems to agree with the above, again, no idea how credible. Highly variable on factors. https://www.youtube.com/watch?v=8Vc-69M-UWk https://www.youtube.com/watch?v=8Vc-69M-UWk
