A card, much like a credit card in that it is linked to a bank account. This card would offer rewards and the reward would be Universal Health Care, either using the system they use now for air miles, cash back, etc., or perhaps a self imposed tax on purchases using this card. A set percentage of any transaction would be taxed at such a percentage as related to the level of care. Personally I would pay 5 cents for every dollar if I knew that I would have universal care. Card also has med info.
