paris carte senior

Here's the information from the French Tourist Office. It points out that it is an annual pass and not good for travel within Paris.

Persons aged 60 years and over are eligible for a 25% discount from SNCF (French Railways System). The discount apply only for travel beginning in a "blue" period, when traffic is light, i.e., times other than Friday and Sundays afternoons, Monday mornings and holidays.
Please check the SNCF calendars, which are available in France. Or you can consult the "Calendrier Voyageurs" on French National Railways website at: http://www.sncf.fr .

If you plan to travel frequently in France over the course of a year, the Carte Senior may be for you.

Reasonably priced, the Carte Senior will allow discounts of 25-59% for one year from the date of purchase. This card is ONLY SOLD in FRANCE.

These reductions are not valid for traveling by train in the Paris area.

Once again, Perry shills for another website without any knowledge that the website can help.

So far as I know, there is no senior card for travel in Paris. Any transportation tickets or passes you buy for Paris will only be good in Paris and its suburbs. For a page that lists all your ticket and pass choices with links to detailed explanations of each one, go here.
