[0046] Specifically, the first processing unit 31 controls the first rotating conveying unit 32 to rotate at a reduced speed, so that the first communication card read-write unit 33 performs a decelerated scan on the communication card. Some track state abnormalities can be eliminated through the decelerated scan, so that the second communication card read-write unit 43 can read and write the communication card normally.

[0047] In at least one embodiment, when the first processing unit 31 obtains that the first communication card reading and writing unit 33 fails to read and write the communication card, the first processing unit 31 reports it through an external device.

[0048] In at least one embodiment, the second near-field communication component 4 includes: a second processing unit 41, a second rotating conveying unit 42 and a second communication card read-write unit 43; the second rotating conveying unit 42 is movably mounted on the first conveying frame 1 or the second conveying frame 2, the second communication card read-write unit 43 is mounted on the second rotating conveying unit 42, and the second rotating conveying unit 42 and the second communication card read-write unit 43 are electrically connected to the second processing unit 41; the second processing unit 41 drives the second rotating conveying unit 42 to rotate so that the second rotating conveying unit 42 pushes the communication card to move in the conveying channel 11; when the second processing unit 41 obtains the track state of the communication card, the second processing unit 41 controls the second rotating conveying unit 42 to adjust the rotation speed in real time according to the track state of the communication card, so that the second communication card read-write unit 43 reads and writes the communication card; when the second processing unit 41 reads abnormal information on the communication card through the second communication card read-write unit 43, the second processing unit 41 drives the second rotating conveying unit 42 to return the communication card to the first near-field communication component 3.

The disclosure and other embodiments can be implemented as one or more computer program products, i.e., one or more modules of computer program instructions encoded on a tangible and non-volatile computer-readable medium for execution by a data processing device or to control the operation of the data processing device. The computer-readable medium can be a machine-readable storage device, a machine-readable storage substrate, a storage device, a material composition that affects a machine-readable propagation signal, or a combination of one or more thereof. The term "data processing unit" or "data processing device" includes all devices, equipment and machines for processing data, including, for example, a programmable processor, a computer or a multiprocessor or a computer group. In addition to hardware, the device may also include code that creates an execution environment for a computer program, for example, code constituting processor firmware, a protocol stack, a database management system, an operating system, or a combination of one or more thereof. A propagated signal is an artificially generated signal, for example, a machine-generated electrical, optical or electromagnetic signal, which is generated to encode information for transmission to a suitable receiver device.

[0065] A computer program (also referred to as a program, software, software application, script, or code) may be written in any form of programming language (including compiled or interpreted languages) and may be deployed in any form, including as a stand-alone program or as a module, component, subroutine, or other unit suitable for use in a computing environment. A computer program does not necessarily correspond to a file in a file system. A program may be stored in a portion of a file that holds other programs or data (e.g., one or more scripts stored in a markup language document), in a single file dedicated to the program, or in multiple coordinated files (e.g., files that store one or more modules, subroutines, or portions of code). A computer program may be deployed for execution on one or more computers that are located at one site or distributed across multiple sites and interconnected by a communications network.

[0066] The processes and logic flows described in this document may be performed by one or more programmable processors executing one or more computer programs to perform functions by operating on input data and generating output. The processes and logic flows may also be performed by, and the apparatus may also be implemented as, special purpose logic circuits, such as an FPGA (field programmable gate array) or an ASIC (application specific integrated circuit).

[0067] For example, processors suitable for executing computer programs include general and special purpose microprocessors, and any one or more of any type of digital computer. Typically, the processor will receive instructions and data from a read-only memory or a random access memory or both. The basic components of a computer are a processor that executes instructions and one or more storage devices that store instructions and data. Typically, a computer will also include one or more mass storage devices for storing data, such as magnetic disks, magneto-optical disks, or optical disks, or operably coupled to receive data from a mass storage device or transfer data to a mass storage device, or both. However, a computer does not necessarily have such a device. Computer-readable media suitable for storing computer program instructions and data include all forms of non-volatile memory, media, and memory devices, including, for example, semiconductor memory devices, such as erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), and flash memory devices; magnetic disks, such as internal hard disks or removable disks; magneto-optical disks; and compact disk read-only memory (CD ROM) and digital versatile disk read-only memory (DVD-ROM) disks. The processor and memory can be supplemented by dedicated logic circuits, or incorporated in dedicated logic circuits.

[0070] Only a few implementations and examples are described, and other implementations, enhancements, and variations can be made based on what is described and illustrated in this patent document.

[0071] A first component is directly coupled to a second component when there are no intermediate components other than a line, trace, or another medium between the first component and the second component. A first component is indirectly coupled to a second component when there are intermediate components other than a line, trace, or another medium between the first component and the second component. The term "coupled" and its variations include direct coupling and indirect coupling. Unless otherwise specified, the use of the term "about" is meant to include a range of 10% above and below the value.
