Although the e-healthcare smart card stores different information in each country, there are many commonalities. Most include personal identification information, so you do not have to repetitively fill out forms. They also contain your social or private healthcare benefits, and can be PIN protected so you have control over who can access your health information.
Some programs go further, providing the capability to carry electronic prescriptions, digitally sign documents and securely access personal healthcare information over the Internet. In some cases personal health information is stored on the card, including allergies or current medications, which can be extremely valuable in an emergency if you are incapable of speaking.
