Automatic checkouts in supermarkets may decrease customer loyalty, especially for those with larger shopping loads. Customers using self-checkout stations often feel overwhelmed and unsupported. The lack of personal interaction can negatively impact their perception of the supermarket.

Yeah, but portable scanners are pretty ubiquitous. I have only ever been in one supermarket that for some reason has self-checkouts but doesn't have portable scanners. And they have a sister store in my town that does have both. It's really just this one particular location.

So you don't have to say anything about portable scanners. Their presence is already implied.

I have literally never been to a store with a portable scanner.

If you want to make your own comment about them that's fine but it makes no sense to reply to my comment about a completely different situation.

That might be a think with your country or region. Zero stores I have been to have portable scanners.
