Abstract

A near field communication (NFC) device, an authentication system using the NFC device and an authentication method thereof are provided. The NFC device includes a RFID tag, a loop antenna, a flexible fabric packaging material and an EMI shielding material. The device can be easily adhered to objects including most handsets for mobile phone services. By adopting the authentication system and the authentication method, the device can be paired with a typical mobile phone and used to authenticate the user, thereby enabling mobile payment and mobile banking activities using mobile phones.

Claims

1. A near field communication (NFC) device, comprising:

a radio frequency identification (RFID) tag, adapted for storing a user identification (ID);

a loop antenna connected to the RFID tag, adapted for sending the user ID to a NFC reader device when the NFC device is near the NFC reader device;

an electromagnetic interference (EMI) shield disposed at a side of the NFC device, adapted for preventing electromagnetic interference and magnetic interference around the side; and

a flexible fabric wrapping material, adapted for completely wrapping the RFID tag, the loop antenna, and the EMI shield.

2. The NFC device as claimed in claim 1, wherein when the NFC device is used in a transaction activity, the NFC device does not record a transaction amount data of the transaction activity.

3. The NFC device as claimed in claim 1, wherein when the NFC device is used in a transaction activity, the NFC device does not calculate a transaction amount data of the transaction activity.

4. A NFC device, comprising:

a RFID tag, adapted for storing a user ID;

a loop antenna connected to the RFID tag, adapted for sending the user ID to a NFC reader device when the NFC device is near the NFC reader device;

a flexible fabric wrapping material, adapted for providing an adhesiveness to adhere the NFC device to an outer shell of an electronic device; and

an EMI shield disposed at a side of the NFC device, adapted for preventing electromagnetic interference and magnetic interference emitted internally from the electronic device;

wherein the flexible fabric wrapping material wraps the RFID tag, the loop antenna, and the EMI shield.

5. An authentication system, comprising:

a NFC device, comprising;

a RFID tag, adapted for storing a user ID;

a loop antenna connected to the RFID tag, adapted for sending the user ID to a NFC reader device when the NFC device is near the NFC reader device;

an EMI shield disposed at a side of the NFC device, adapted for preventing electromagnetic interference and magnetic interference around the side; and

a flexible fabric wrapping material, adapted for completely wrapping the RFID tag, the loop antenna, and the EMI shield;

the NFC reader device, wherein when the NFC reader device is near the NFC device, the loop antenna obtains the user ID; and

a certification authority center connected to the NFC device through the Internet, adapted for obtaining the user ID and performing a user authentication action according to the user ID.

6. The authentication system as claimed in claim 5, further comprising:

an application server connected to the certification authority center; and

an application terminal connected to the application server, wherein after the user authentication action is completed, the certification authority center sends user authentication data to the application server, and the application server and the application terminal process, refresh, or update at least a transaction amount or at least a service data.

7. The authentication system as claimed in claim 6, wherein after the user authentication action is completed, the certification authority center sends an identity related data corresponding to the user ID to the application server.

8. The authentication system as claimed in claim 6, wherein after the user authentication action is completed, the certification authority center sends an authentication success message to the application server.

9. An authentication method, adapted for a NFC device, the authentication method comprising:

obtaining, at a NFC reader device, a user ID of a RFID tag in the NFC device with;

performing a user authentication action with an application terminal, and further sending the user ID and a transaction data to a certification authority center;

after the certification authority center completes the user authentication action, sending an authentication success message, the user ID, and the transaction data to an application server; and

refreshing, at the application server, a transaction record or a service record of an account corresponding to the user ID, wherein the NFC device does not record any transaction amount data or service data.

10. The authentication method as claimed in claim 9, further comprising:

after the certification authority center completes the user authentication action, sending an identity related data corresponding to user ID to the application server; and

refreshing a transaction record or a service record of an account corresponding to the user ID with the application server; and

after the application server refreshes the transaction record or the service record, sending a transaction success message to the application terminal in order to notify the user.
