For what it's worth, what you have is a Visa Debit (or Mastercard Debit) card, though the branding on them isn't consistent. Debit cards that can't interop with the Visa/Mastercard networks do exist, I have one .. mostly because I'm lazy and haven't asked for a change.

Dunno how rare they are, I suspect rare, but I can't find any numbers with a quick search.

All of Canada uses debit cards that don't work over the credit network. Some banks allow you to request a VISA number that's linked to your chequing account (for online use only), but debit cards use the separate Interac system.

Interesting. I should have been clear:

I suspect debit-only cards are rare in the US. Outside the US: No clue at all.

I have heard debit-only cards in the US referred to as "ATM cards" occasionally, but that was a few years ago. I think if an account belongs to a minor child, it may not be possible to get a regular debit card (that also works with the credit card network), but an ATM card may be possible? That's the only reason I'm aware of to get one.
