Actually, many do, especially the big retailers. They just haven't turned them on yet. Ingenico iSC250 and 350 models, both of which are NFC- and Chip-capable (it's in their datasheets), are popping up all over the place, and the other manufacturers are keeping up. Walmart has already turned their Chip readers on, for example. Even the third-party CC handlers are starting to encourage smaller retailers to swap out their PIN pads for newer chip-capable ones, again for liability reasons.
