We currently support two devices and will add support for more in the months to come. Please request an invite and let us know if there are particular hardware devices you are interested in us supporting.

How does the hardware work with the web SDK? I didn't think it was possible to interface with hardware from a browser.

Verifone supports HTML subset for user interface, I'd imagine that's the only thing you can customize.
