I've read all the answers on here about the pass but I want to know much more. What size does the photo have to be? Can I buy a pass for my friend and can she stick in the photo when I give her the pass or does it have to be done at a station? What are the zone choices? I heard there is 2 parts to the card; do you have to buy some kit separately? How do you activate it because I read it is valid up to 10 years? What's the current prices? What 's the difference between this and the Navigo Decouverte? Finally, are there any passes that cover weekends?
in fact, navigo is just the new carte orange.
so for the price, so you have, with the navigo card, three different time length for navigo:
the difference beetween navigo and navigo decouverte is navigo vanilla is personal and you have to go to an ratp office because they took a photo of directly in the chip card. fro vanilla navigo, there are only one part.the vanilla is only for Parisian people.
the navigo decouverte is the two part card more like the old carte orange. easier to get, you can have it without to go to ratp.there are two part. a chip card without identity and and a card where you write your name and put a photo. you need to have cards to travel but it's the chip car the card who need to be recharged.
i think you buy a card for you friend and put photo after.
about the choice for zone, as i said before, the smallest subscription is zone 1 and 2 but the zone 3 is quite near( for exemple you have la defense in zone 3) you can see all the maps in english there http://www.ratp.fr/plan-interactif/carteidf.php?lang=uk but if you take a small zone, you can buy a "complement de parcours" and go outside.
NEVERTHELESS there are other subscriptions as paris visite, for exemple.
