Verifone payment terminal

I saw this normal screen gas station this morning whan trying to get gas. I put in my credit card, but nothing works. I took the card out.

New attempt to put in the credit card made something strange to happened: The card terminal rebooted. I got several screens with all kinds of system information until the device went to some info screen

This screen tells some software version information and that it looks like this device is connected to Ethernet network (or at least tries to connect to one).

Then some application starting information…

I think nothing really interesting (in technical or security wise) was revealed.

Finally a screen that tells that the payment terminal was closed at the moment.

This event caused me to be curious what kind of hardware and software this payment terminal uses. So I did some Google searching for information on this Verifone mx760.
