Is PIN entry with Square's new readers secure?

[jzw95]

Just to tie this up, Allie has posted about the recent release of the official PCI standards for PIN on glass, so any further discussion should take place there.

PCI standards for PIN on glass with COTS

There are now PCI standards for PIN on glass with commercial off the shelf devices (i.e. Square in the UK and Aus). This could be a huge game-changer as it’s now an endorsed, fully accepted method of PIN entry. Will iZettle, etc embrace it? What does it mean for accessibility? Update - I edited to make this clear I’m referring to PIN on glass with COTS devices. There have been a few PIN on glass implementations on custom hardware complaint with the old standards - e.g. Clover Mini.
