I believe I am reading the webpages correctly, but thought I would double-check here.

When we go to Paris, we always use our Carte Orange and buy a new coupon hebdo. It appears that Paris now has a smart card system, Navigo, which is starting to replace the Carte Orange.

We would not mind getting one of these instead, cause we love London's Oyster card and all others of its ilk, but when I read the form it looks like I need to have a Paris address or some sort of certification from my employer in Paris.

Is this correct? Can I not just pick one up when I get there?
