storing, by the electronic device, the biometric data of the user of the mobile device and the identification data of the mobile device that was received from the mobile device and a biometric pin, wherein the electronic device is configured to only store one time the biometric data of the user of the mobile device and the identification data of the mobile device that was received from the mobile device and the biometric pin;

receiving a request from the mobile device, by the electronic device, for authenticating the user of the mobile device, the request including biometric data captured by the mobile device and identification data of the mobile device;

performing, by the electronic device, a first comparison between the biometric data stored in the electronic device and the biometric data included in the request, and a second comparison between the identification data of the mobile device stored in the electronic device and the identification data of the mobile device included in the request; and

sending to the mobile device, by the electronic device, a response to the request for authenticating the user of the mobile device based on a result of both the first comparison and the second comparison, the response to the request for authenticating the user of the mobile device including the biometric pin if the result of both the first comparison and the second comparison is that there is a match,

wherein the response to the request for authenticating the user of the mobile device is for use by the mobile device to perform an operation based on the authentication of the user.

2. The method of claim 1 , wherein the identification data of the mobile device includes a serial number, an International Mobile Equipment Identity (IMEI), and an Integrated Circuit Card IDentifier (ICCID).

3. The method of claim 1 , wherein the electronic device receives from the mobile device and sends to the mobile device through at least one of a wireless communication or a wired communication, and

wherein the wireless communication comprises at least one of Wi-Fi communication, Near Field Communication (NFC) communication, Radio Frequency IDentification (RFID) communication, or Bluetooth communication.

4. The method of claim 1 , wherein the operation performed by the mobile device based on the authentication of the user comprises at least one of a network login, a device login, or a financial transaction.

5. The method of claim 1 , wherein the biometric data comprises at least one of a single fingerprint, a multiple finger fingerprint, a palm print, an iris scan, a voiceprint, a facial recognition without motion adjustment, a facial recognition with motion adjustment, a repeatable motion, a repeatable key input, or a repeatable touchscreen input.

6. The method of claim 1 , further comprising emulating, by the electronic device, at least one of a contactless card and a credit card.

7. The method of claim 1 , wherein if the user of the mobile device is authenticated, the mobile device displays on a display at least one of an image or alphanumeric characters for identifying the user of the mobile device.

8. The method of claim 1 , wherein the electronic device has an exterior surface that has printed thereon or embedded therein at least one of an image or alphanumeric characters that is visible from the outside for identifying the user of the mobile device.

9. The method of claim 1 , wherein the electronic device is configured to be worn by the user of the mobile device.

10. The method of claim 1 , wherein the electronic device forms at least one of an IDentification (ID) card, a driver's license, a credit card, a government security card, a corporate security card, a badge, an access card, or public transportation card.

11. The method of claim 1 , wherein the electronic device is disposed in a case configured to at least one of physically couple or retain the mobile device.

12. An electronic device for use with a mobile device for biometric authentication of a user of the mobile device, the electronic device comprising:

a memory configured to only store one time biometric data of a user of the mobile device, identification data of the mobile device, and a biometric pin;

a transceiver configured to communicate with the mobile device; and

a processor configured to communicate and control the memory and the transceiver to:

receive from the mobile device biometric data of the user of the mobile device that was captured by the mobile device and identification data of the mobile device,

store one time the biometric data of the user of the mobile device and the identification data of the mobile device that was received from the mobile device and the biometric pin,

receive a request from the mobile device for authenticating the user of the mobile device, the request including biometric data captured by the mobile device and identification data of the mobile device,

perform a first comparison between the biometric data stored in the memory and the biometric data included in the request, and a second comparison between the identification data of the mobile device stored in the memory and the identification data of the mobile device included in the request, and

send to the mobile device a response to the request for authenticating the user of the mobile device based on a result of both the first comparison and the second comparison, the response to the request for authenticating the user of the mobile device including the biometric pin if the result of both the first comparison and the second comparison is that there is a match,

wherein the response to the request for authenticating the user of the mobile device is for use by the mobile device to perform an operation based on the authentication of the user.

13. The electronic device of claim 12 , wherein the identification data of the mobile device includes a serial number, an International Mobile Equipment Identity (IMEI), and an Integrated Circuit Card IDentifier (ICCID).

14. The electronic device of claim 12 , wherein the transceiver is configured to communicate with the mobile device through at least one of a wireless communication or a wired communication, and

wherein the wireless communication comprises at least one of Wi-Fi communication, Near Field Communication (NFC) communication, Radio Frequency IDentification (RFID) communication, or Bluetooth communication.

15. The electronic device of claim 12 , wherein the operation performed by the mobile device based on the authentication of the user comprises at least one of a network login, a device login, or a financial transaction.

16. The electronic device of claim 12 , wherein the biometric data comprises at least one of a single fingerprint, a multiple finger fingerprint, a palm print, an iris scan, a voiceprint, a facial recognition without motion adjustment, a facial recognition with motion adjustment, a repeatable motion, a repeatable key input, or a repeatable touchscreen input.

17. The electronic device of claim 12 , wherein the electronic device further includes a card emulator for emulating at least one of a contactless card or a credit card.
