Abstract: A device is configured to operate in a first mode of operation during which the device is configured to receive a first supply voltage in a contactless manner. The device includes a light emitting element and a first circuit. The first circuit is configured to receive a second supply voltage generated from the first supply voltage. A first current is generated from the first supply voltage, independent from the second voltage, and applied to the light emitting element which is selectively turned on.
