Hello @AhmedAlshemi 

Thank you for your post. 

If you bought the ticket at a ticket machine and it was printed out, it means it wa actually paid. 
What do you mean exactly by "travel card"? Do you have a SwissPass?

For more information you can call our colleagues at the SBB Contact Center (0041 848 44 66 88, CHF 0.08/Min).

Thank you and have a nice day
