On my last visit to UK I noticed some EMV transactions taking as long as a minute+ to process.

I would like to see an article that would do a fair, 2-sideed analysis of pros and cons, costs and benefits, status quo v. EMV v. other alternatives, types of frauds in the swipe world v. types of frauds in the chip world... etc. Picking a number (e.g. 30% fraud reduction) even if its true may be an argument good enough to satisfy a pundit but not to provide a serious input to the discussion.

And no Karen, when something is too complex, the solution is not "to move together at the same time". The solution is to simplify it or find other solution.
