A medical ID wallet card gives medical information in an emergency. It is conveniently sized to fit in your wallet or purse, and it has a bold red medical alert symbol printed on the front. Inside, there's a place for your name, emergency contact information, phone, physician name, blood type, medical conditions, allergies, and medications. Although not a replacement for a medical id bracelet, persons with a chronic medical condition consider it an important addition to help provide safety and security in the event of an emergency.
