Such an EHICard is spread since 2004 in European countries - I have my "default" insurance card definitly more than 10 years already and its backside has the EHIC design.
However, that still doesn't protect you from paying for a transport back to your home country. For those cases a travel health insurance is still a good choice - there are vendors offering them for 6 € per year already and cover also things like cancelling a journey. Even if not the slightest thing happens that money is more than wisely spent.
Dude, you're more than 2 years too late! Too bad.How about free beer if you still show up? *luring*
