Mine is a Barclaycard Arrival+ (http://www.barclaycardarrival.com/). It is not a PIN-primary card, but it absolutely works in PIN mode at automated PoS systems.
PenFed (https://www.penfed.org/visasignaturepoints/) also offers a true chip-and-PIN EMV card in the US (again, signature priority, but I've verified the PIN works at PoS).
I don't think your JPMC card has a PIN assigned to the chip. Its PIN can only be used at an ATM to get a cash advance.

Barclays is a British bank fwiw. They're likely to have all the infrastructure in place.
