Abstract

An integrated dual-frequency card issuer device comprises a microprocessor STM32F101 circuit, a power supply circuit, an induction antenna and reading / writing circuit, a JTAG interface circuit, an STM32_ISP circuit, and an RS232 serial port circuit. The induction antenna and reading / writing circuit includes a 13.56M card reading / writing module ZLG522S and a 2.4G card reading module SHNM100. The microprocessor STM32F101 circuit exchanges data with an external radio-frequency application through the card reading module and at the same time exchanges data with a host computer through the RS232 serial port circuit. The STM32_ISP downloading circuit and the JTAG interface circuit carry out software upgrading and debugging of a system of the host computer. The power supply circuit supplies power for all components of a card reader. The invention provides the highly-reliable integrated dual-frequency card reader device with high-efficiency extension.

Description

technical field [0001] The invention relates to a radio frequency card issuer device integrating 13.56MHZ and 2.4GHZ dual frequency bands, especially for mobile payment SIMpass, RF-SIM and other multi-band and multi-application mobile phone radio frequency applications to provide dual-band card issuing services. Background technique [0002] With the development and progress of mobile short-distance communication technology, technologies such as RF-SIM and SIMpass based on short-distance radio frequency communication of mobile phones have been widely developed and applied. The application of the above technologies is gradually being applied to banks, access control, public transportation, computer systems, mobile payment, Popularization in fields such as consumer payment. [0003] However, under current circumstances, most radio frequency applications are only compatible with one frequency band radio frequency, that is, different radio frequency devices are often required fo...
