I found my old NaviGo card from our trip to Paris a few years ago, it's in one of those plastic cases with a passport type photo. Is it still able to be recharged? Or was this something you use and toss, I can't remember? If it is rechargeable I'd hate to toss it when we went through the trouble to get the photos, etc.

Any info would be appreciated!

It says Carte Nominative Transport on the part that has my photo on it and the navigo card slips in behind it, not sure if that helps to know what I'm talking about.

Does it look pretty much like this:

then you can reload it with a weekly or monthly pass.

.... that is, for up to 10 years.....

Yes that's it! It's only 3 years old so I can recharge it? Do I do that at the ticket counter or do they have machines in the station? I remember it being very handy to have last time!

There are machines - payment method might be 'chip/pin' credit card, though, or maybe cash. I have only done it at the ticket window in RER station (orig purchase, and then 1 reload). I have read recently, here or Tripadvisor, that you can also reload at other outlets such as local tabac, etc. that show the RATP sign or are listed on the website.

Was just in Paris this month, and we recharged ours at machines in the stations. Won't take American credit card but will take a 20 euro bill. A week's recharge is 18 euros and some change.

Thank you, that's perfect, appreciate the info!
