## Abstract

An antenna is configured to receive authentication information through wireless communication from a mobile device adapted to be carried by a user. A detector is configured to perform detection of approach or contact of an object to be detected with respect to the antenna based on a change in an electrostatic capacitance. A control device is configured to validate the detection in response to an approval of authentication of the mobile device that is performed with the authentication information.

## Claims

### Claim 1

An authentication system, comprising:
an antenna configured to receive authentication information through wireless communication from a mobile device adapted to be carried by a user;
a detector configured to perform detection of approach or contact of an object to be detected with respect to the antenna based on a change in an electrostatic capacitance; and
a control device configured to validate the detection in response to an approval of authentication of the mobile device that is performed with the authentication information.

### Claim 2 (depends on 1)

The authentication system according to claim 1,
wherein the control device is configured to control an operation of a device to be controlled based on the authentication and the detection.

### Claim 3 (depends on 2)

The authentication system according to claim 2,
wherein the device to be controlled is a locking/unlocking device configured to lock/unlock a reclosable body.

### Claim 4 (depends on 3)

The authentication system according to claim 3,
wherein the antenna and the detector are incorporated in a knob adapted to be used to open/close the reclosable body.

### Claim 5 (depends on 3)

The authentication system according to claim 3,
wherein the reclosable body is installed in a mobile entity.

### Claim 6 (depends on 1)

The authentication system according to claim 1,
wherein the antenna is a loop antenna.

### Claim 7 (depends on 1)

The authentication system according to claim 1,
wherein the antenna is configured to receive the authentication information through proximity wireless communication and short-range wireless communication; and
wherein the device to be controlled is configured to switch between a state that the antenna receives the authentication information through the proximity wireless communication and a state that the antenna receives the authentication information through the short-range wireless communication, until the authentication is approved based on either the proximity wireless communication or the short-range wireless communication.

### Claim 8

A user interface device, comprising:
an antenna configured to receive authentication information through wireless communication from a mobile device adapted to be carried by a user;
a detector configured to perform detection of approach or contact of an object to be detected with respect to the antenna based on a change in an electrostatic capacitance; and
a processor configured to validate the detection in response to an approval of authentication of the mobile device that is performed with the authentication information.
