Navigo Reader is an Android application developed by JonathanMM that allows users to read their Navigo Passes using the NFC feature of their phone. This app is compatible with both silver and blue Navigo Passes.

With Navigo Reader, users can easily access information about their passes, including their validities and last validations. It is worth noting that the app does not send any information to third parties or store the data, as it is only read. The app does not write or modify any data on the Navigo Pass.

If there is any unknown data, such as stations or operators, users can help update the app's database by opening a ticket on the project's website.

It is important to note that Navigo Reader is not an official app and is not affiliated with any transportation authority or operator.
