Abstract
Disclosed is an NFC device without a power button. The NFC device includes a battery that outputs a battery voltage, an internal system that includes a voltage receiving terminal for receiving the battery voltage and a reset signal receiving terminal for receiving a reset signal, and maintains a reset state in response to the reset signal having a first state, and an NFC tag circuit that generates the reset signal having the first state, and generates the reset signal having a second state in response to only a system power on command included in a system power on NFC signal transmitted from an external near field communication (NFC) device, in which the internal system releases the reset state in response to the reset signal having the second state, and then, generates a reset release holding signal using the battery voltage, and transmits the generated reset release holding signal to the NFC tag circuit, and the NFC tag circuit generates the reset signal maintaining the second state according to the reset release holding signal.
