[0023] The accompanying drawings are provided to further understand the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation thereof.

[0024] Figure 1 This is a modular structure diagram of a portable mobile clip-on terminal according to an embodiment of the present invention. Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 As shown, this utility model embodiment provides a portable mobile clip terminal, including a mobile clip shell, in which a motherboard PCBA, a display module, a fingerprint module and a battery module are embedded; the motherboard PCBA is electrically connected to the display module, the fingerprint module and the battery module respectively.

[0027] In this embodiment, the motherboard PCBA includes a main control unit, a power management unit, a power on / off control unit, an audio unit, a wireless communication unit, a card reader microcontroller unit, a contact IC card unit, a PSAM card unit, a magnetic stripe unit, a keypad unit, and a contactless IC card unit. The motherboard PCBA is a printed circuit board assembly, where electronic components, i.e., various units, are mounted on a printed circuit board (PCB) and formed into a complete circuit system through processes such as soldering.

[0028] The main control unit is implemented using an MPU microprocessor. The main control unit (MPU) is bidirectionally connected to the power management unit (PMU) and the power on / off control unit. The power management unit (PMU) controls the power input and output to ensure stable operation of the terminal. The power on / off control unit is an existing power on / off circuit controlled by the main control MPU, which in turn controls the power on and off of the terminal.

[0029] Furthermore, the power-on / off circuit has two pins connected to the main control MPU, one for input and one for output. The pins are active high and are low by default.

[0030] Further, the master MPU is electrically connected with the power management unit PMU through the first communication module, and the two communicate bidirectionally. The first communication module is used to realize data transmission and communication between the master unit and the power management unit, such as the power management unit PMU transmitting battery status, power, charging status, etc. to the master unit, and the master unit outputting control instructions to the power management unit PMU to control the start or shutdown of the battery, etc. The master MPU is electrically connected with the third communication module of the audio unit through the second communication module, and the input end of the audio unit is connected with the output end of the master unit. The second communication module and the third communication module are used to realize transmission of audio data and control instructions, such as the MPU transmitting data after analyzing the audio format file to the audio unit, and the audio format file (audio data) being integrated into the terminal when the device is shipped.

[0031] In some embodiments, the first communication module is a 12C communication module, the second communication module is a 12S communication module, and the third communication module is a 12S communication module, all of which are existing communication chips.

[0032] The master unit is electrically connected with the wireless communication unit through the first serial port, and the two communicate bidirectionally. The wireless communication unit includes a Bluetooth module and a Wifi module. The Bluetooth module and the Wifi module by default include their antennas, and no additional description is made. The Bluetooth module and the Wifi module can communicate with user devices through Bluetooth or Wifi, such as a user using a tablet computer to communicate with the MPU to realize reading of an ID card, a bank card, a fingerprint, and password input, etc.

[0033] The master unit is also connected with a display screen module. The display screen module is used to display data collected by the master unit, and provides users with intuitive and clear visual interactive experience. The display screen module can adopt an LCD display screen or an OLED display screen.

[0034] The master unit is electrically connected with the card reading microcontroller unit MCU through the second serial port, and the two communicate bidirectionally. The master unit sends various instructions, such as card reading instructions and password input instructions, to the card reading microcontroller unit through the second serial port. The card reading microcontroller unit sends instruction execution results, such as card reading results and passwords, to the master unit through the second serial port. The master unit analyzes and processes the received information to complete corresponding bank business functions. Further, in the communication process, the card reading microcontroller unit can also send state information, such as card reading success / failure and card insertion / removal, to the master unit. These state information helps the master unit to understand the current state of the terminal, so as to perform corresponding processing or prompt the user.

[0035] The main control unit is also electrically connected to the fingerprint module, and the two communicate bidirectionally. The main control unit is used to control the fingerprint module's start-up, stop, and fingerprint acquisition operations through commands, ensuring that the fingerprint module works at the correct time and under the correct conditions. The fingerprint module is used for fingerprint acquisition and recognition. It captures the user's fingerprint image through a high-precision fingerprint sensor and compares the acquired fingerprint image with the built-in existing fingerprint recognition algorithm to provide reliable authentication and determine the user's identity. Furthermore, the fingerprint module also has security protection functions.

[0036] Furthermore, the main control unit sends corresponding instructions to the fingerprint module, such as starting fingerprint collection, stopping collection, and registering fingerprints, and receives the fingerprint images collected by the fingerprint module for user authentication.

[0037] In some implementations, the main control unit, power management unit, audio unit, wireless communication unit, card reader microcontroller unit, and fingerprint module are all implemented using existing components. Various existing modules can achieve the functional effects of this invention, and there is no specific limitation on the component models used in specific units or modules. For example, the main control unit can be implemented using an RK3399 MPU; the power management unit can be implemented using a BQ25730; the audio unit can be implemented using an AW8733T; the wireless communication unit can be implemented using a Wi-Fi / Bluetooth integrated AP6212; the card reader microcontroller unit can be implemented using an STM32; and the fingerprint module can be implemented using a Goodix GT-511C3 or FPC1020.

[0038] In this embodiment, the power management unit is a PMU (Power Management Unit), which includes a PMU chip and a power conversion chip. The PMU chip and the power conversion chip are electrically connected. The power conversion chip can provide 5V and 3.3V power (power conversion converts the battery power from the PMU into the 5V and 3.3V required by the terminal). The PMU chip and the battery module are electrically connected via power leads, and the connection is bidirectional. The PMU chip manages the battery module, such as real-time monitoring of the battery module's power status (e.g., remaining power, charging status), controlling the battery charging process to ensure safe charging, triggering a low-power warning when the battery is low and sending it to the main control unit for feedback, and having a comprehensive protection mechanism. Using an existing PMU chip, the corresponding power management functions inherent in the chip itself can be realized.

[0039] The PMU power management unit is also bidirectionally connected to an external power adapter. When the battery module's power is insufficient, it can be charged by an external power source or directly powered by an external power source to power the back clip terminal.

[0040] In some implementations, the battery module uses a high-density capacity battery and includes two battery power leads and two grounding wires.

[0041] In this embodiment, as Figure 1 As shown, the card reader microcontroller unit, or card reader MCU unit, is bidirectionally connected to the contact IC card unit, PSAM card unit, magnetic stripe unit, keypad unit, and contactless IC card unit.

[0042] Specifically, the card reader MCU unit includes an IC communication module and a GPIO communication module. The card reader MCU unit is electrically connected to the contact IC card unit and the PSAM card unit via the IC communication module. The contact IC card unit is used for reading contact IC cards and uploads the read data to the card reader MCU unit via the IC communication module. Furthermore, the card reader MCU unit sends a read command to the contact IC card unit via the IC communication module. The contact IC card unit receives the command, executes the corresponding operation, and returns the result data to the card reader MCU unit. The card reader MCU unit transmits the returned data to the main control MPU and displays it on the display module. The PSAM card unit is used to receive SAM cards and provides IC card-level security protection. During interaction with some contact cards, the card reader MCU unit will first confirm data exchange with the PSAM before communicating with the IC card. The card reader MCU unit is electrically connected to the magnetic stripe card unit via the GPIO communication module. The magnetic stripe card unit is used for reading magnetic stripe cards and uploads the read data to the card reader MCU unit via the GPIO communication module.

[0043] Specifically, the card reader MCU unit also includes a third serial port and a fourth serial port. The third serial port is electrically connected to the national cryptographic chip in the PIN pad unit. The PIN pad unit is used for user password input and data encryption / decryption, uploading the password data to the card reader MCU unit. The PIN pad unit includes a national cryptographic chip and a keyboard, with the chip electrically connected to the keyboard. The card reader MCU unit is electrically connected to the contactless IC card unit via the fourth serial port. The contactless IC card unit is bidirectionally connected to the antenna board. The contactless IC card unit, also known as the RFID card unit, is used for reading contactless IC cards and second-generation ID cards, uploading the read data to the card reader MCU unit via the fourth serial port.

[0044] In some implementations, the contact IC card unit, PSAM card unit, magnetic stripe unit, keypad unit, and contactless IC card unit are all implemented using existing components. Various existing modules can achieve the functional effects of this invention, and the specific component models used for each unit or module are not specifically limited. For example, the contact IC card unit can be implemented using an NFC IC; the PSAM card unit can be implemented using the NXP A7000 series or Broadcom BCM5821; the magnetic stripe unit can be implemented using a Magnetic Card Reader IC; the keypad unit can be implemented using a 16-key matrix keypad from Keysight Technologies; and the contactless IC card unit can be implemented using the NXP MFRC522 (RF card module).
