If I have to give out my card details anywhere especially for a subscription based service I look beforehand on how I can cancel it. Companies have no shame in leaving you forget a subscription going on forever. That should be punishable by law.
Also my main bank is now Monzo (based in the UK) and there I get a notification on my phone for every transaction I make. I also see a list of all the committed spending for a month which includes all subscription based services I have (some of them I had to mark myself as such because Monzo can't distinguish if they are recurring or not). To be honest I think every mobile bank application should offer this out of the box. It's 2020...
