Detailed Implementation

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

As shown in Figure 1, 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.

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.

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.

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.

Furthermore, the main control MPU is electrically connected to the power management unit (PMU) via a first communication module, enabling bidirectional communication between the two. The first communication module facilitates data transmission and communication between the main control unit and the PMU. For example, the PMU transmits battery status, charge level, and charging status to the main control unit, while the main control unit outputs control commands to the PMU to control the battery's startup or shutdown. The main control MPU is electrically connected to the third communication module of the audio unit via a second communication module. The input terminal of the audio unit is connected to the output terminal of the main control unit. The second and third communication modules are used to transmit audio data and control commands. For instance, the MPU transmits the parsed audio format file (audio data) to the audio unit. This audio format file is integrated into the terminal at the factory.

In some implementations, the first communication module is an I2C communication module, the second communication module is an I2S communication module, and the third communication module is an I2S communication module, all of which are existing communication chips.

The main control unit is electrically connected to the wireless communication unit through the first serial port, and the two communicate bidirectionally. The wireless communication unit includes a Bluetooth module and a Wi-Fi module. The Bluetooth module and Wi-Fi module include their antennas by default, and no further explanation is given. They can communicate with user devices via Bluetooth or Wi-Fi. For example, users can use a tablet computer to communicate with the MPU to realize functions such as reading ID cards, bank cards, fingerprints, and password input.

The main control unit is also connected to a display module, which displays the data collected by the main control unit, providing users with an intuitive and clear visual interactive experience. The display module can be an LCD display or an OLED display.

The main control unit is electrically connected to the card reader microcontroller unit (MCU) via a second serial port, enabling bidirectional communication. The main control unit sends various commands to the MCU via the second serial port, such as card reading commands and password input commands. The MCU sends the command execution results, such as card reading results and password information, back to the main control unit via the second serial port. The main control unit parses and processes the received information to complete the corresponding banking functions. Furthermore, during communication, the MCU can also send status information to the main control unit, such as card reading success/failure and card insertion/removal. This status information helps the main control unit understand the current terminal status and thus take appropriate action or provide user notifications.

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.

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.

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.

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.

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.

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

In this embodiment, as shown in Figure 1, the card reader microcontroller unit, i.e., the 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.

Specifically, the card reader MCU unit includes an I²C 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 I²C 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 I²C communication module. Furthermore, the card reader MCU unit sends read commands to the contact IC card unit via the I²C communication module. The contact IC card unit receives the commands, executes the corresponding operations, 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 first confirms the 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.

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.

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.
