Forget those bulky medical file folders. Early in the century ahead, at least for US military personnel, medical records may be carried on a necklace in a modification of the GI dog tag and/or on a smart card. Both approaches are part of a study beginning this month and continuing through February.
This proposed computer-era dog tag, called a personal information carrier (PIC), provides eight megabytes of data. When coupled with a small-sleeve adapter, the PIC allows reading or updating of medical data through most computers, from desktop models in hospitals to handheld or laptop models in field medical units.
