The Bionic CIO

Harvard Medical School’s John D. Halamka has a computer chip implanted under the skin of his right arm that carries a numeric key to his medical history. If he is ever admitted to a hospital unconscious or incoherent, health-care workers will be able to use a special reader to learn his name, the medications he takes, his allergies, and any major illnesses he has suffered. Of course, there’s always the risk that his chip will set off the security alarms at Wal-Mart—not to mention the more serious risk of identity theft. Would those risks be worth it to you?
