The actual usefulness of these cards depends hugely on where you're living. In the UK there aren't any exchanges and banks can often get the hump and shut you down if you sell via Localbitcoins more than a couple of times.

Because of that cards were extremely useful as they never touch any bank account.

If you're somewhere in mainland Europe then there's not much point and never really has been. SEPA and slightly less hostile banks make them kind of pointless.
