2. The system according to claim 1, wherein the beacon identification information is different from a patient ID and wherein the interface correlates information received from the transceiver with a patient associated with the beacon identification information.

3. The system according to claim 2, wherein the transceiver receives encrypted patient data from a diagnostic or test apparatus, associates the encrypted patient data and the beacon identification information, and transmits the encrypted patient data and the beacon identification information to the hospital system wirelessly or by a wired connection, and the interface correlates beacon identification information with a patient ID.

4. The system according to claim 1, further including:

a body coupled communication device connected with an appliance or a caregiver which, when the caregiver or appliance is touching or in close proximity to the patient, performs at least one of receiving the beacon identification from the transmitting unit and communicating an identification of the appliance or caregiver to the transmitting unit.

5. The system according to claim 1, wherein the flexible circuit includes a receiving unit that receives body coupled communications that:

(i) request transmission of the beacon identification information;

(ii) convey a caregiver identification from a treating caregiver; and

(iii) convey monitored physiological, administered medication, or clinical lab data,

wherein the receiving unit is connected with the memory to store the caregiver information and the monitored physiological, administered medication or clinical lab data.

6. The system according to claim 1, wherein

the memory is configured to store an encryption key,

the wireless transmitting unit is configured to transmit the encryption key via the body coupled communication protocol to physiological sensors mounted in body coupled communication contact with the patient, and the receiving unit is configured to receive encrypted physiological data from the physiological sensors via the body coupled communication protocol.

7. The system according to claim 1, further including:

a body coupled communication device connected with an appliance or a caregiver which, when the caregiver or appliance is touching or in close the patient, communicates an identification of the appliance or caregiver to a receiving unit of the flexible circuit which stores the identification of the appliance or caregiver in the memory of the flexible circuit.

8. The system according to claim 7, wherein the flexible circuit transmits the stored identification of the appliance or caregiver when the wireless transmitting unit is in bodied coupled communication with the transceiver, the transceiver transmitting the identification of the appliance or caregiver to the medical database.

9. The beacon system of claim 1, wherein the processor encrypts the beacon identification and communicates the encrypted beacon identification to the transceiver in response to the transceiver issuing a request to the processor via body coupled communication.

10. A hospital system comprising:

a plurality of beacon apparatuses for attachment to a plurality of patients;

each beacon apparatus comprising;

a strap of flexible material configured to be attached to an extremity of a patient;

a printable layer attached to the strap;

a flexible power supply attached to the strap; and

,

a flexible circuit attached to the strap and the power supply, the flexible circuit including;

a wireless transmitting unit which wirelessly transmits at least beacon identification information;

a memory that stores at least the beacon identification information and an encryption key; and

,

a processor that at least encrypts the beacon identification information with the encryption key and communicates the encrypted beacon identification information from the memory to the transmitting unit for transmission on the patient'"'"'s body via the body coupled communications;

a transceiver for receiving the encrypted beacon identification information from the beacon apparatuses and transmitting information to the beacon apparatuses;

a medical facility system connected wirelessly or by a wired connection with the transceiver for storing and retrieving patient information, the medical facility system including an interface which decrypts the encrypted beacon identification information and correlates received beacon identification information to a patient associated with the beacon identification information;

a diagnostic or testing apparatus for receiving encrypted beacon identification information from the transceiver and providing encrypted diagnostic or test information and the associated encrypted beacon identification information received from the transceiver to the medical facility system; and

,

a display and user input device connected with the transceiver.

11. The system according to claim 10, wherein the diagnostic or testing apparatus electronically associates the beacon identification information with the diagnostic or test results, communicates the beacon identification information and the diagnostic or test results to the transceiver which transmits the associated beacon identification information and diagnostic or test results to the interface of the medical facility system.

12. The hospital system of claim 10, wherein the diagnostic or testing apparatus includes an IV pump which receives the encrypted beacon identification information from the transceiver and provides encrypted diagnostic information including medical dosage information to the medical facility system.

13. The hospital system of claim 10, wherein the diagnostic or testing apparatus includes a blood pressure monitor which receives the encrypted beacon identification information from the transceiver and provides encrypted diagnostic information including blood pressure and pulse rate information to the medical facility system.

14. A method of associating information with a patient, the method comprising:
