receiving biometric information of the caregiver; and

authenticating the caregiver using the biometric information.

10. A terminal apparatus of a caregiver, the terminal apparatus comprising:

a card recognizer configured to recognize a smart card of a patient;

a memory having stored therein instructions; and

a processor being controlled by the instructions and performing a method, the method comprising:

transmitting, to the smart card, first time information corresponding to a point in time when the terminal apparatus recognizes the smart card a first time, the smart card being first recognized when the caregiver starts a care service for the patient;

receiving first encrypted data including encrypted first time information from the smart card and storing the first encrypted data, the encrypted first time information being generated at the smart card by encrypting the first time information using an encryption key pre-stored in the smart card; and

transmitting the first encrypted data to a management server when the terminal connects to the management server,

wherein the terminal apparatus has no decryption key and the management server has a decryption key corresponding to the encryption key,

wherein, when the card recognizer recognizes the smart card a second time, the method further comprises:

transmitting, to the smart card, second time information corresponding to a point in time when the terminal apparatus recognizes the smart card the second time, the smart card being second recognized when the caregiver ends the care service for the patient;

receiving second encrypted data including encrypted second time information from the smart card, the encrypted second time information being generated at the smart card by encrypting the second time information using the encryption key; and

transmitting the second encrypted data to the management server when the terminal apparatus connects to the management server,

wherein the method further comprises determining a present time so as to acquire each of the first and second time information,
