Constituting method for access control system with novel two-dimensional bar code

Abstract

The invention relates to a constituting method for an access control system with a novel two-dimensional bar code, and an access control method in the field of information processing. The constituting method is characterized in that an access control system is provided, for the access control system, an admission ticket can be printed by a low-precision printer; ticket information can be embedded on the paper admission ticket without influencing the appearance of the ticket; meanwhile, the access control system is anti-counterfeiting; the access control system can be used for an access control system of an automatic gate; and the access control system can be in common use with an RFID (radio frequency identification devices) card. Problems of high cost of currently used magnetic medium admission ticket, complicated configuration of the automatic gate and frequent maintenance of the current admission tickets can be solved by the introduction of the technology. Meanwhile, the conformity of real-name ticket-buying and automatic real-name ticket-checking is realized, and the automatic checking of travelling content and the anti-counterfeiting information of admission ticket are realized. Therefore, the technological development of access control management of large public places and modern traffics is improved by the constituting method for the access control system with the novel two-dimensional bar code.

Description

technical field [0001] The invention belongs to the field of information processing, in particular to a method for constituting a novel two-dimensional barcode access control system. Background technique [0002] With the rapid development of our country's economy, the application and development of barcode technology has attracted the attention of various fields such as tax stamp anti-counterfeiting and commodity anti-counterfeiting. [0003] The bar code was first invented by a graduate student of the business department of Harvard University in the United States. The original idea was: the customer selects the product he needs through the product list, and takes the card corresponding to the product printed by the punch card machine to the pick-up window. You can get the desired goods. Stores can use this card to correct inventory, or as an application form to charge customers. As such an advanced logistics method, it was not popularized due to the excessively low labor...

Problems solved by technology

However, in low-precision printing, such as printing with a precision below 200dpi, each dot matrix has exceeded the size invisible to the naked eye calculated by the Rayleigh criterion. Into the effect? How to achieve anti-counterfeiting effect while embedding information? This will be the problem to be solved in this patent application
