Abstract: A portable healthcare electronic data security key for an individual that is configured for use in combination with a portable computerized data access device that can wirelessly communicate with the key through complementary close proximity or NFC circuitry such that when the access device is positioned in close proximity to the key, the key communicates a security protocol to the access device that instructs the access device to utilize the Internet (or another communications network) to remotely access and retrieve with the proper authorization provided by the key at least a portion of the individual's electronically stored medical records from a remote database and display those retrieved medical records on the access device's user display. The security protocol can also instruct the access device to send an alert to emergency contacts identified by the individual in the key or in the database.
