New Fall U-Pass

So starting in fall quarter, we have the new shiny U-Pass, which works like the Orca card right? So my question is, when is it activated? Will it start the first day of quarter, earlier, or not until tuition is paid in full? (I picked mine up in spring quarter, so I've got it, but when will it work?)

Not sure if anyone will know, but thought it'd help to ask

Thanks ♥
