In the embodiment of the present application, the induction coil 2 is configured to generate an induction current according to a bank card contactless transaction request signal sent by a contactless bank card reader/writer, so as to supply power to the central processing unit. In the embodiment of the present application, the induction coil 2 generates an induction current through electromagnetic induction when receiving any electromagnetic signal, and the generated induction current is used for starting the central processing unit 1 and supplying power to the central processing unit 1. In the embodiment of the application, the bank card non-contact transaction request signal sent by the non-contact bank card reader-writer is also an electromagnetic signal, that is, the induction coil 2 generates an induction current when receiving the bank card non-contact transaction request signal sent by the non-contact bank card reader-writer, so as to supply power to the central processing unit 1, and start the central processing unit 1 to operate. In the embodiment of the present application, the number of turns of the induction coil 2 may be 10 or more and 20 or less.
In a specific embodiment of the present application, the contactless bank card reader/writer may be a post with NFC functionality, and the contactless bank card transaction request signal may be an NFC signal.

When the user uses the non-contact bank card to conduct transaction, the non-contact bank card is far away from the non-contact bank card embezzlement alarm, for example, the non-contact bank card is taken out of a wallet to conduct transaction, and therefore the non-contact bank card embezzlement alarm cannot receive a transaction request and cannot give an alarm.
In the embodiment of the application, in order to further prevent the user bank card from being embezzled, the size of the induction coil 1 is set to be larger than that of the induction coil included in the common non-contact bank card. The induction coil 1 in the alarm for embezzling the non-contact bank card is sensitive to receive electromagnetic induction signals compared with the common bank card, can find and receive the electromagnetic signals faster than the common bank card and consume the electromagnetic signals, so that the signals sent by the non-contact bank card reader-writer are effectively shielded, the non-contact bank card is difficult to receive the signals sent by the non-contact bank card reader-writer, or the signals are too weak to respond to the signals.
In a specific embodiment of the application, the number of turns of the induction coil 1 in the contactless bank card embezzlement alarm of the application is greater than that of the induction coil contained in the ordinary contactless bank card. In the embodiment of the application, the size of each circle of the induction coil 1 in the contactless bank card embezzlement alarm of the application is the same as or similar to that of the induction coil in the common contactless bank card.
