Detailed ways

Introduced below are some of the various embodiments of the present invention and are intended to provide a basic understanding of the present invention. It is not intended to identify key or critical elements of the invention or to delineate the scope of what is claimed.

The purpose of the present invention is to provide a device, which can make a user's mobile terminal (such as a mobile phone) behind the device, and the user's mobile terminal and the device are automatically connected to form a POS device, and optionally, the The device can also have the function of charging the user's mobile terminal. Since electromagnetic induction is generated between the device and the mobile terminal, we will hereinafter refer to the device as an "electromagnetic induction device".

First, the electromagnetic induction device of the present invention will be described.

FIG. 1 is a schematic diagram showing the structure of an electromagnetic induction device according to an embodiment of the present invention.

As shown in FIG. 1 , an electromagnetic induction device 10 according to an embodiment of the present invention includes: a coil 11 for generating an induced current through electromagnetic induction; a current measurement module 12 for detecting changes in the induced current generated by the coil 11 ; The control processor 13 receives the output from the current measurement module 12, and controls each module of the electromagnetic induction device; the contactless processing module 14 realizes contactless processing; the code scanning module 15 reads and parses the barcode information by scanning the code; And the communication module 16 is used to realize short-distance communication with the outside; the safety processor 17 is used to process the contactless signal obtained by the contactless processing module 14, and transmit the control signal from the main control processor 13 to the contactless processing module 104 . Here, the communication module 16 is, for example, a short-range communication module such as a Bluetooth module, which is used for connection and communication with the user's mobile phone. In addition, the electromagnetic induction device 10 further includes a power supply (not shown) for supplying power and generating a current in the coil.

Moreover, as shown in FIG. 1 , the electromagnetic induction device 10 is in the form of a triangular prism, wherein the step coil 11 is placed under the surface A of the triangular prism to prevent “charging current” from inducing the mobile terminal on the A surface of the electromagnetic induction device. . Its induction principle is the electromagnetic induction principle of wireless charging.

A coil is placed under the A side of the triangular prism, which is used to inductively "charge" the mobile phone placed on the A side of the device. Its principle is the principle of electromagnetic induction of wireless charging, as shown in Figure 2. FIG. 2 is a schematic diagram showing an electromagnetic induction method between the electromagnetic induction device of the present invention and a mobile terminal.

As shown in FIG. 2 , the power transmission coil (here, the coil 11 of the electromagnetic induction device) generates alternating current of a certain frequency, which is generated in the power receiving coil, here the internal coil of the mobile terminal (such as a smartphone) through electromagnetic induction. certain current. In this way, the current measuring module 12 can judge whether the electromagnetic induction device 10 is "charging" the user's mobile phone by measuring whether the current changes, and thus can judge whether the user places the mobile terminal on the device A surface.

when the change of the induced current is detected, the communication module of the electromagnetic induction device is started, and correspondingly, the mobile terminal senses that the mobile terminal is being charged, the communication module of the mobile terminal is started to be connected with the communication module of the electromagnetic induction device, meanwhile, the mobile terminal starts a corresponding payment and receipt function, and the payment and receipt function controls the electromagnetic induction device to perform code scanning operation or non-receiving operation.

14. The method of claim 13, wherein the code scanning and the non-acceptance are performed by a plurality of processors,

in the induced current obtaining step, whether the electromagnetic induction device and the mobile terminal are close to each other is judged by judging the magnitude of the induced current generated between a first coil in the electromagnetic induction device and a second coil in the mobile terminal.

15. A computer-readable storage medium, on which a computer program is stored, which, when being executed by a processor, carries out a handover control method of non-accepted physical and scan code reading according to claim 13 or 14.

16. A computer device comprising a memory, a processor and a computer program stored on the memory and executable on the processor, characterized in that the processor implements the handover control method of non-accepted physical and scan code reading of claim 13 or 14 when executing the computer program.
