This is the most unpractical card ever sold. The fact that it is digital and that in no way you can get a physical one mean that you MUST have always a good internet connection AND that the APP works. If that doesn’t happen you’re screwed and must pay full price ticket. Don’t buy it unless you travel A LOT and you’ll have more chances of managing to use it out of all the times you actually take the train Honestly, save the money and avoid having just more problems than you need for a thing that is supposed to help you.
