Hello Guzaida50
Thanks for the feedback.
I would have described it differently, yet to stay in line with the information given on the SBB / ZVV websites I used that term.
In the past, when all customers still had the blue abonnement card, they indeed had to deposit the physical card at a counter for the time they did not want to use the travel card. Nowadays, it just requires a click in their IT system, if applicable. The term itself, however, is still used.
Keep in mind that we are not the SBB customer service, we are a help page run by volunteers. We do speak multiple languages, not all perfectly, though.
Have a nice day,
Roland
