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. An authentication system, comprising:

a NFC device, comprising;

a RFID tag, storing a user ID;

a loop antenna connected to the RFID tag, 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, preventing electromagnetic interference and magnetic interference around the side; and

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

wherein when the NFC reader device is near the NFC device, the loop antenna communicates the user ID to the NFC reader device;

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

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.

2. The authentication system as claimed in claim 1, 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.

3. The authentication system as claimed in claim 1, wherein after the user authentication action is completed, the certification authority center sends an authentication success message to the application server.
