Answer:
Give the patients RFID tags to identify their medical records
Step-by-step explanation:
Radio-Frequency Identification (RFID) identifies, automatically, tracking tags assigned to objects through electromagnetic fields sent, actively or passively by the tags attached to the object.
The RFID tag sends wireless digital data giving the identification number in response to interrogatory electromagnetic signal emitted by a RFID reader device that is in range
The identification number can then be translated to give the complete specification of concerning the tag
As such a patient putting in the tag, automatically opens up is medical record as he moves from doctors to blood labs to pharmacies within the same hospital.
