Control display and network system substituting integrated circuit card

Abstract

The invention relates to a control display and network system substituting an integrated circuit card. A plurality of service browsers, a cashier dispenser, a network charger, an optimal computer and a database server and the like of certain network unit form a service station by adopting local area network technology. The optimal computer of each service station is connected with a router in the internet by a distinguishing computer to form a safe and reliable special service wide area network. The control display is provided with a microprocessor and a memory and is equipped with input keys and miniature liquid crystal display and the like. The invention needs to be online for information processing and does not need to be online for authorization, and can substitute the existing various IC cards. The invention can substitute the control display of a bank for realizing 'paperless transaction' and 'cashier flow reduction'. The network charger is equipped with the microprocessor for identifying and controlling software, the memory, a read-write device and a display and the like. The network charger adopts bar code technology, and the invention can be applied to the fields of retail trade, manufacturer, financial insurance, book management and warehouse automation management and the like.

Description

technical field [0001] The invention relates to network interconnection technology, computer technology and display technology. Display technology is a skillful combination of microelectronics and display technology. Background technique [0002] At present, various integrated circuit (IC) cards or optical storage cards do not display the message or information contained in the existing paper vouchers replaced by them, and are not vouchers in the true sense. [0003] The electronicization of various businesses in all walks of life, including e-finance, e-commerce, e-government, e-military, e-medical, e-official, e-business, e-transportation, e-logistics and other systems, is mainly carried out based on the Internet. The characteristics of the Internet are anytime, anywhere, easy to use, instant interaction, etc., which provide a good solution for the interaction and sharing of information flow, transaction flow, capital flow, logistics, etc. of various businesses, all-weath...

Problems solved by technology

But each firewall must be open to the vendor to access the equipment in question, which itself would be a security risk

When the network size is large, managing the firewall becomes difficult

[0011] Secure Socket Layer (Secure Socket Layer, SSL) VPN is only suitable for site-to-network connections, and cannot achieve secure interoperability between multiple networks

[0012] The existing automated IC card reader cannot conduct business through a public network (such as the Internet)
