6. The communication apparatus according to claim 2, wherein the request signal is transmitted in response to an operation by the user of the communication apparatus.

7. The communication apparatus according to claim 6, wherein the notification unit is configured to notify by using sound.

8. The communication apparatus according to the claim 6, wherein the notification unit is configured to notify by using light.

9. The communication apparatus according to claim 6, wherein the first communication unit is configured to transmit the request signal and receive the response signal by using a proximity communication method.

10. The communication apparatus according to claim 9, wherein the proximity communication method is a non-contact communication method according to NFC standards.

11. A communication method comprising:

transmitting, by a first communication unit using a first communication method, a request signal to another communication apparatus;

receiving, by the first communication unit, a response signal that includes information which specifies a communication method selected from a plurality of communication methods, which are each different from the first communication method, by a user of the another communication apparatus in response to the request signal;

transmitting, by a second communication unit and by using the communication method, authentication information to the another communication apparatus in response to a determination that communication with the another communication apparatus is possible based on the response signal received by the first communication unit; and

notifying, by a notification unit, a user of the communication apparatus after the response signal is received by the first communication unit,

wherein a communication range of the second communication unit is greater than a communication range of the first communication unit.

12. The communication method according to claim 11, wherein notifying the user of the communication apparatus is after the response signal is received by the first communication unit and the second communication unit receives a result of authentication based on the authentication information.

13. The communication method according to claim 12, wherein the response signal includes setting information for communication with the another communication apparatus via the second communication unit.

14. The communication method according to claim 13, wherein the setting information is address information.

15. The communication method according to claim 13, wherein the setting information is authentication method information.

16. The communication method according to claim 12, wherein the request signal is transmitted in response to an operation by the user of the communication apparatus.

17. The communication method according to claim 16, wherein sound is used for the notifying.

18. The communication method according to the claim 16, wherein light is used for the notifying.
