Good point, but allowing a device given away for free to anyone with a bank account to test a PIN opens up a much bigger risk than limiting it to merchant terminals.

I think you're really overstating the difficulty of acquiring a merchant terminal, which are available at literally any shop or restaurant that accepts cards.

You know the EMV specification is open and anyone could write software to check a PIN using a standard smartcard reader (10$ on Amazon), right?
