Data or information about patients has been used to identify who they are for treatment, payment, research or government use. Despite the use of many identifiers we continue to have issues with duplicate records or misidentification of patients at hospitals and clinics.
Biometrics have been used effectively in various industries for some time, using fingerprints or other physical traits to identify individuals. Hospitals are now beginning to use these same technologies to counteract this issue of misidentification of patients. It is likely your palm-veins or iris will be scanned in the future to verify your identity.
