The sixth chapter card fees / meal selling system

Introduction 1, charge system

Charging system (canteen management system) is the most advanced modern food system, it adopts theinduction card this cutting-edge products, combined with modern design and management, with advanced technology, reliable safety, no maintenance, change thetraditional dish meal sale, ticket, find tedious workchange. To improve efficiency, enhance themanagement. The advantages of investing in one step, is to improve the management level of enterprises,enterprises and institutions, to achieve the best choice formeal selling computer operation.

Induction card name for non-contact radio frequencycard, has the advantages of non-contact, no loss,induction is essentially a semiconductor chip, direct memory read and write data, less susceptible to interference from the external environment, so it issuitable for electronic wallet, business card systems,enterprise a cartoon system, highway automatic chargingsystem and the bus ticket vending system.

2, system.

This system composed of PC workstation, 485communication card, 485 cable, fee charging terminal,supporting the management of software component. The system structure diagram as follows:

3, function characteristics

● easy scalability

Each PC workstation can manage 200 terminals, if thedining room number or the larger the number can increase the workstation can manage more terminal.

Super large capacity

Database uses this system is SQL SERVER database, itscapacity is adequate for tens of thousands of enterprises scale.

The efficient, rapid, convenient, accurate

Immediate settlement, real-time query, retrieval; provides a variety of statements complete, save a lot of manual labor, greatly improve the working efficiency, the operator can grasp the business business card system.

● cross enterprise zone

Realization of real time data exchange many businessarea, it is very useful to have several different locations ofbusiness enterprises. It is easy to realize multi Enterprises

The district centralized management, a common card,partition billing and other functions.

● safety, reliability

The use of radio frequency card instead of cash, theconsumption process of cardholders and sales are notcoming into contact with cash, all operations were completed in the terminal POS, directly to the account the amount of deduction, each transaction system are automatically recorded. Key data are encrypted, for all the data of the whole system, can realize the automaticbackup multi drive, just specify the backup path.According to the need or manual disk backup.

The terminal can set various charging methods, meet the needs of different users

The user can according to need to set arbitrary amount,measured way, way, way of quota recipes;

● terminal according to the business hours set period, the automatic switch machine

● backup battery can power off 8 hours of operation.

● consumption restriction function, to protect the interests of users to maximize

When consumption exceeds a set amount of time will not allow the user to consumption (the highest consumptionamount can be set by the system), high safety;

● real-time report

Consumer correction function

In the process of consumption if the amount of input error, can according to the transaction records werewashed on the workstation, to protect the interests ofcardholders.

● real-time subsidies, view the consumption records,check the operation log, make the management moreclearly. Through the network, the other is access to that computer can real timely and dynamically view the variousdata;

4, charge system hardware description
