I’ve treated myself to a credit card holder which offers protection from
people trying to scan my card. It wasn’t at all expensive – about £3 I
think.

Well, exactly. These cards have been around since 2012 so I'm
wondering why all the fuss now.

A few links below - by the way, for people saying about numbers being
synced, yes, the store will have to be synced as always.

But the card won't be - that's not how these card work, or indeed the
number entry pads the bank give you. Neither are wirelessly synced to
anything.

Yes, a bit scary. I wonder what the cost of producing such cards would be
and whether the cost would outweigh what is lost via fraud.

I can see that the technology to change the number within the card wouldn't
be too problematic but I'm wondering how the retailer would know if that is
the correct security number.
