ABSTRACT
Environmental protection is a permanent problem in the contemporary social development situation. In order to reduce the paper waste and protect the environment, the paperless electronic business card is proposed. One can communicate through the business card information on the computer, and verify the authenticity of the business card through an electronic database. The electronic business card is mainly based on Single Chip Micyoco technology. The core theories of the electronic paperless-card are embedded technology and Bluetooth wireless transmission technology. The society is the place for frequent exchanges with the rapid development of market economy, business, and market competition. The electronic business card is a portable electronic instrument. The electronic paperless-card needs a low power supply voltage, small size, low power consumption and high-speed microprocessor as the main controller chip. The electronic business card completes the data input, data storage, and search functions mainly by using STM32C8T6 module.
