      @lsaiz Luis, as mentioned this was the template for ISO/IEC 7816, EMV. The invention & premise was adopted from prior M4 from Bull-CP8.

      @lsaiz Luis, Swipe is a single motion. EMV Dip is a timed sequence of events and it is not abundantly clear when it ends in the US EMV model

      @BrianRoemmele Really? How many tenths of a second take swipe vs dip? Do you have the numbers? How many times a swipe needs a retry?

      @lsaiz Luis, yes befuddlement has both a mechanical and cognitive load. Empirical field research shows the drag effect is massive in the US

      @lsaiz Luis, not an intelligence metric. It is about generations of prior card behavior. You grew up with EMV, US did not. Befuddlement.

          @lsaiz Luis, my data suggests the start of the transition was earlier in Spain. January, 2005 was the end date ext to 2008. Started in 1995.
