I don't see any indication on their website or marketing materials that they are accepting the PIN. I would be surprised if they did, because EMVCo have been firm in the past that a dedicated keypad is required. I would be interested to know whether they're either capping the amount that can be charged, or are taking some of the liability themselves. Square will also be looking to get as many people on contactless as possible, because with Apple Pay / Android Pay you can exceed the usual capped limit in the UK (I believe it's something like £30 with a regular contactless card before PIN entry is required).
