Metro Card UPDATE: Effective yesterday, you can top off your CDMX Metro Card in the CDMX app. It's call "AppCDMX" in the apple or google play store. Once loaded, look for the icon that says "Recarga Tarjeta MI". But unfortunately it's only for temporary/permanent residents and citizens. Because you need an account through the government. But for visitors, reloads still work in certain convenience stores, and kiosk in the city.
