Compared with traditional industries, the one card industry is an emerging industry that has developed with the development of information technology. It was introduced from abroad, but has distinct Chinese characteristics in its application in China. It is closely related to the management of underlying hardware devices, card related tourists, and HR. The intelligent one card system integrates many new technological achievements in the fields of smart cards, automatic control, biometric recognition, computer software and networks, databases, and information security. In the era of information technology revolution, it has shown vigorous vitality.

With more and more companies choosing to use the one card system, it also heralds the arrival of a new era of overall industry operation systems. In today's increasingly deepening application of the one card industry, customers are no longer choosing a single product provider, but more from the perspective of their own company's overall operation, looking at the management of the "characters" within the entire enterprise from a global perspective. Therefore, such enterprises tend to be more rational when selecting suppliers. The high-quality platform of the one card system and the overall system that can grow together with users in the long run are often the first factors for users to weigh, rather than the previous situation of rushing to launch the system independently to solve a specific problem.

The main applications of the one card system include group version E-HR software, attendance series, access control and elevator control series, consumption and energy-saving series, visitor and counter signature series, parking lot series, channel and ticket checking series, patrol series, etc.
