The TP Card looks to be a variant of the stored-value IC cards like Suica [1][2] used for transit and e-money payments across Japan, but with a fixed commuter pass and no recharge functionality.
The linked thread includes a comparison [3] between the TP Card and a regular Suica.
Just FYI for anyone wondering about the photo, this is actually Google's office in King's Cross. "Campus London" was further east and looked more like a coworking space.

I like the straightforward explanation this site provides. That said, I tend to use http://example.com to trigger captive portals because it's an IANA reserved domain [1] that other people can't register.
This gives me confidence to browse to it without fear that the domain could lapse in the future and get taken over (e.g. in a watering hole attack).
