The device may have a finger-ring housing that surrounds a finger-shaped opening to allow the device to be worn on a finger of a user. The coil may be formed from metal traces on a printed circuit that wrap around the finger-shaped opening. Near-field communications circuitry in the device may be used to gather near-field communications tag information. The tag information may be gathered in response to user input. Wireless communications circuitry that uses a non-near-field communications antenna may wirelessly transmit the tag information and/or other information such as user input to a companion device. ## Claims ### Claim 1 A ring device, comprising: a ring-shaped housing; sensors including a motion sensor and a fingerprint sensor mounted in the ring-shaped housing; and near-field communications circuitry that is configured to emulate a near-field communications tag, wherein information from at least one of the sensors is configured to trigger an operation with the near-field communications circuitry. ### Claim 2 (depends on 1) The ring device defined in claim 1 wherein the motion sensor comprises an accelerometer. ### Claim 3 (depends on 1) The ring device defined in claim 1 wherein the near-field communications circuitry includes a near-field communications reader. ### Claim 4 (depends on 3) The ring device defined in claim 3 wherein the near-field communications reader is configured to obtain tag information from a near-field communications tag in response to the information. ### Claim 5 (depends on 4) The ring device defined in claim 4 wherein the information comprises information associated with user input. ### Claim 6 (depends on 5) The ring device defined in claim 5 wherein the user input comprises movement of the ring-shaped housing that is detected with the motion sensor. ### Claim 7 (depends on 4) The ring device defined in claim 4 wherein the sensors comprise a microphone and wherein the information comprises audio input detected by the microphone. ### Claim 8 (depends on 4) The ring device defined in claim 4 wherein the motion sensor is configured to detect gesture input. ### Claim 9 (depends on 8) The ring device defined in claim 8 wherein the gesture input comprises at least one of tapping and shaking. ### Claim 10 (depends on 8) The ring device defined in claim 8 wherein the gesture input comprises pointing input. ### Claim 11 A ring device, comprising: a ring-shaped housing configured to be worn on a finger; sensors mounted in the ring-shaped housing, wherein the sensors include a motion sensor and at least one of a temperature sensor, an ambient light sensor, and a health sensor; and a near-field communications reader configured to obtain tag information from a near-field communications tag in response to information from the motion sensor. ### Claim 12 (depends on 11) The ring device defined in claim 11 further comprising wireless communications circuitry configured to use non-near-field wireless communications to transmit the tag information. ### Claim 13 (depends on 11) The ring device defined in claim 11 wherein the motion sensor is configured to detect gesture input. ### Claim 14 A ring device, comprising: a sensor configured to detect gesture input in a virtual reality environment; and wireless communications circuitry configured to send control signals to an electronic device based on the gesture input, wherein the wireless communications circuitry comprises near-field communications circuitry selected from the group consisting of: a near-field communications tag reader and a near-field communications tag emulator. ### Claim 15 (depends on 14) The ring device defined in claim 14 wherein the electronic device has a display and wherein the control signals are configured to adjust content on the display. ### Claim 16 (depends on 14) The ring device defined in claim 14 wherein the sensor is configured to detect user input that includes at least one of tapping and shaking and wherein the sensor is selected from the group consisting of: an accelerometer, a compass sensor, a gyroscope, and an inertial measurement unit. ### Claim 17 (depends on 16) The ring device defined in claim 16 wherein the near-field communications circuitry is activated in response to the user input. ### Claim 18 (depends on 16) The ring device defined in claim 16 wherein the near-field communications tag reader is configured to obtain tag information from a near-field communications tag in response to the user input. ### Claim 19 (depends on 18) The ring device defined in claim 18 wherein the wireless communications circuitry is configured to provide the tag information to the electronic device. ### Claim 20 (depends on 14) The ring device defined in claim 14 wherein the electronic device is configured to create the virtual reality environment.
