Abstract:
An NFC card emulation device including a button press confirmation circuit, a time-out determination unit, and a control circuit. The time-out determination unit is formed by adopting discrete components, such as, the second diode, the second resistor, the third resistor and the second capacitor, etc. When the NFC card emulation device approaches the card reader, the card reader supplies energy to the NFC card emulation device and charges the second capacitor by the control circuit, and when the NFC card emulation device is removed from the card reader, the control circuit realizes the timing function by the second capacitor; if, within the timing period, it is determined that the button press confirmation has been performed, it is determined that the button press confirmation is valid. Such a time-out determination unit has a simple structure and a low cost.

Claim (Index 5):
The device of  claim 1 , wherein the button press confirmation circuit comprises:\n a button, a second unidirectional conducting tube, a first resistor, and a first capacitor; and a first end of the second unidirectional conducting tube is connected to the control circuit, a second end of the second unidirectional conducting tube is grounded via the button and the first capacitor which are connected in parallel, and the first resistor is connected with the second unidirectional conducting tube in parallel.
