Always makes sense of having a separate card for online stuff (shop, subscriptions, etc). But having to go to the bank and renew, create a new one, the waiting lines.

Some banks have web/mobile banking where you can restrict actions/limits/transactions, so it's a good option too.

Others have virtual cards for this purpose, but these are not offered in a lot of countries (revolut, privacy, yandex money, etc).

I guess the amount of hassle is specific to the country. The last time I had to go to a physical branch here was… 2006 maybe?

You apply for the card online and get it in the post.
