In the UK there is traditionally a semi-religious approach in refusing to at least make available national and nationally recognised (as opposed to club membership, etc.) ID cards. The UK has only ever had them during wartime (needs must, you see) but within Europe they were in use long before the Common Market, never mind the EU, was established (contrary to what a different semi-religious belief would insist). The various different European ID cards were then standardised and adopted EU-wide. The UK continues to be different and insist everyone else is wrong. In both the UK and EU, situations arise when people need to identify themselves and (uniquely ?) the UK leaves its people and organisations/companies/etc. without the availability of the useful tool of a simple card to instantly facilitate this - for ideological reasons. To my knowledge, anybody without an ID card in the EU (lost, wallet stolen, etc.) can readily replace it but must then identify themselves to get it - but that is a piece of cake because the details are on file and can readily be verified by the person presenting themselves. Not having such a system is a complication, not a simplification - it is however the UK way.
