Detailed ways

The present invention will be described in further detail below according to the drawings and embodiments.

As shown in Figures 1-4, the portable mobile transaction device includes an STM32 processor, and a multi-function card reader module, a dot matrix printer module, a keyboard input module, a power supply module, and a status indication module that are respectively connected to the STM32 processor. , USB communication interface module;

The multi-function card reading module is used to read the information stored in different transaction cards and send it to the STM32 processor; the STM32 processor is used to analyze the data of the card reading module, keyboard input module, and USB communication interface module and output control signals to other modules; The dot matrix printer module is used to receive the information of the STM32 processor and print out the transaction voucher; the power module is used to provide the working power of the device and lithium battery management; the status indication module is used for status prompt; the USB communication interface module is used for STM32 and PC Ciphertext interaction between client software. the

The multifunctional card reading module includes: ISO7811 magnetic stripe card reading circuit, IS014443 radio frequency card circuit, IS07816 contact IC card reading circuit;

The ISO7811 magnetic stripe card reading circuit, the IS014443 radio frequency card reading circuit, and the IS07816 contact IC card reading circuit are respectively connected to the STM32 processor. The STM32 processor sends the card reading control command and reads back the user in the card according to the card type. information. the

The power module includes: a power management circuit, an external DC socket and a MINI USB socket, and a lithium battery;
