Abstract: A system for maintaining and updating patient data that includes: a magnetic card reader; a magnetic card; a memory chip on the magnetic card, where the memory chip stores patient data; and a biometric reader attached to the magnetic card reader. Preferably, the card reader updates patient data stored in the memory chip when the magnetic card is swiped through the magnetic card reader. The card reader may also enable a monetary transaction when the magnetic card is swiped through the magnetic card reader. In one additional feature, the patient data is stored on a remote database, where the patient data on the remote database is updated when the magnetic card is swiped through the magnetic card reader.
