Does anyone know why UK folk are having extra passport checks?

Just got back from a trip to Scandinavia and a lot of UK folk (myself included) have had to have their 'passport details updated' on their system. Just curious if anyone knows why? I didn't want to sound unhelpful (and it took like 1 min so wasn't an issue, just curious!) but am wondering what that actually means. Assuming it's another B word 'benefit' of some kind but I could be wrong. I know there's some new EU legislation coming in relatively soon but I don't think it was related to that
