The system is mainly used for consumption management of consumption places such as canteens and shops in schools. In the dining hall, the ID card is issued to the dining staff instead of the money ticket, and the card is paid for on the rice machine when the meal is served. When the card is not enough, the money can be recharged. All the dining data is processed centrally through the computer network, and the meals are quickly sold to the canteen, which eliminates the long queue of users; reduces the operating cost of the use unit and improves the management level of the entire canteen. The card can also be used in a variety of consumer locations, with cards in the shopping and entertainment venues of designated stores (such as cinemas, tearooms, and chargeable rooms).
DL-XF-03T ID card charge management system
1. Electronic money: The ID card issued and recharged can be used as a credit card in the unit instead of cash. Make the internal consumption of the unit electronic and institutionalized. Such as for shopping, dining, parking charges, borrowing books, making long distance calls, collecting water and electricity, etc.
The use of this system will eliminate the circulation of meals and cash in the canteen, save the cost of ticket production and supplement, prevent ticket loss and forgery, prevent loopholes in the circulation, and effectively block the pollution caused by the circulation of the ticket and the spread of germs. At the same time, it simplifies the eating process, saves the ticket counting process, improves work efficiency, and effectively controls and strengthens financial and cash control. In particular, the canteen dining, booking meals and other data directly into the computer management, creating extremely favorable conditions for the automation of the entire canteen management.
2. Data collection: The charging machine must be initialized before use. During initialization, set the basic parameters of the toll collection machine, including the user's internal authorized user, the card number of the ID card and the amount in the card, the loss of the card, the blacklist card, the current date, time, and the test data of the toll collection machine. When the whole system is in normal use, the computer needs to collect the consumption details of each vending machine as the data source for settlement.
3. Data settlement: Collect the collected data to form a daily consumption list. Then, the summary is made to form the total revenue of each toll machine on a daily basis. Various audits are performed on the data during collection and aggregation, including legality check, deletion of duplicate data, re-settlement of supplementary data, and final report generation, which facilitates financial accounting or supervision of the income of each consumer.
The data settlement system will perform blacklist detection on the collected data. The so-called blacklist refers to the loss of a card or an invalid card number or an illegal recharge card. A suspicious illegal card is detected by checking whether the card number of each consumption record is valid, whether the balance in the new card is greater than the amount in the old card in the balance library. The operator can view the corresponding ID card holder.
First, the system features:
1. Complete system function
The system can realize the issuance management, deposit, withdrawal, refund and inquiry, report loss, data statistics and provide various business reports for the canteen consumption ID card.
2. High reliability, high stability networking
3. Flexible system structure
Units of different scales, natures, and requirements may choose different system structures according to actual conditions.
4. Complete fault handling technology
The system can continue to work if any device in the system fails or various unexpected events occur.
5. Powerful extensions
According to the needs of enterprises, the system can be expanded into enterprise RFID/xinpin/yikatong/'target='_blank'> card.
Second, the system composition
1, ID card introduction:
(1) ID card is uem4100 compatible format EN card, the chip adopts high-speed CMOS EPROM technology, capacity 1K, data retention period is 10 years, read unlimited times. The ID card has no power supply and has its own antenna. It contains encryption control logic circuit and communication logic circuit. The communication between the card and the reader adopts the international DES and RES secret cross algorithm, which has high security and security. Strong.
ID card has a global unique 32-bit serial number, divided into 16 sectors, each sector is 4 blocks, the block is the smallest read and write unit, each block is 16 bytes, each sector has a separate set of passwords Users can flexibly define access control for each sector.
The ID card operates at a frequency of 125 kHz and the communication speed is 106 KB. The typical transaction process is <100 ms. It also has an anti-collision mechanism.
