Title: Cell phone case having nfc reader and ble
Inventor: WON BAE JUNG
IPC: H04W4/80
Filed: 2020-02-05
Abstract: The present invention relates to a mobile phone case equipped with a near field communication (NFC) reader and a Bluetooth low energy (BLE) unit and, more specifically, to a mobile phone case equipped with an NFC reader and a BLE unit including an extended antenna while an NFC power of a mobile phone extends to a cover of the mobile phone case through a coupling antenna and the extended antenna. According to the present invention, the mobile phone case comprises an NFC reader detecting a tag of a card and a BLE unit transmitting a tag detection result from the NFC reader to the mobile phone, thereby allowing directly transmitting the tag detection result from the mobile phone case to the mobile phone. Since the extended antenna is turned on/off through the NFC reader according to whether the cover is opened or closed, power consumption can be reduced by detecting a card only when the cover is opened or closed. Since the NFC reader is installed in the mobile phone case, whether the card is lost can be detected only by the mobile phone case without intervention of the mobile phone. Since the NFC power of the mobile phone extends to the cover of the mobile phone case, the tag provided on the card is recognized without a separate power supply, and thus whether the card is lost can be determined. In addition, the tag of the card is detected with the extended antenna only when the cover is opened or the mobile phone is moved by using the NFC reader, and thus battery consumption of the mobile phone can be minimized.
