I. Introduction:
Traditional canteens and restaurants mostly use meal tickets or cash for settlement. This inevitably has problems such as cross-infection of germs, long queues, and loss of meal tickets and cash due to poor management. In order to fundamentally solve the above-mentioned problems and improve the management level of canteens and restaurants, our company specially introduces canteen IC consumption management system to users.
The non-contact IC/ID card is a member of the card family. The proximity card encapsulates the memory (semiconductor chip) and antenna on the PVC card, and directly stores and reads the data, and the bit error rate is almost zero. In the process of reading and writing the card, there is no need to directly contact the card reader, there is no wear, and no maintenance is completely required. Since the semiconductor and antenna are completely enclosed, they are not as easily damaged by external environmental interference as magnetic cards or barcodes, and have good reliability and long life.
2. Introduction of IC consumption management system:
The 485 networked meal selling system is developed by collecting opinions and suggestions from a large number of customers, carefully analyzing the pros and cons of other systems, and adopting the latest technology. It is safe and reliable, easy to use, powerful, and hygienic. It is very suitable for schools, enterprises and institutions. It realizes the computerized management of canteens, improves management efficiency, and eliminates loopholes. After a lot of practice, the product has been put on the market, it has proved that the product is stable and reliable, the function meets the actual demand, and the product is leading the domestic counterparts.
(1) The disadvantages of traditional rice selling:
1. Frequent circulation is the source of infection of diseases and bacteria.
2. Easy to damage and inconvenient to store and carry.
3. Ordering meal tickets when buying meals, the process of finding meal tickets is tedious and time-consuming.
4. The method of ordering meal tickets is used in business statistics, which is neither convenient nor accurate.
5. The accumulated cost of meal ticket printing is relatively high.
6. Without safety measures, it is easy to imitate.
(2) Compared with the traditional way of selling rice, the non-contact IC system has the following characteristics:
1. The system uses a non-contact card, also known as a radio frequency card, which is a new technology developed in the world in recent years. It successfully combines radio frequency identification technology and IC card technology to solve the problem of passive (in the card). The problem of no power supply) and no contact is a major breakthrough in the field of electronic devices.
2. High reliability: There is no mechanical contact between the non-contact card and the reader, avoiding various failures due to contact reading and writing. In addition, there is no exposed chip on the surface of the non-contact card, and there is no need to worry about the chip falling off, electrostatic breakdown, bending damage, etc., which not only facilitates the printing of the card, but also improves the reliability of the card.
3. Convenient and fast operation: Due to the non-contact communication, the reader can operate the card within the range of 5-8cm, so there is no need to insert or remove the card, which is very convenient for users to use. The non-contact card has no directionality when used. The card can be swept across the surface of the reader in any direction to complete the operation, which greatly improves the speed of each use.
4. Anti-collision: There is a fast anti-collision mechanism in the non-contact card, which can prevent data interference between the cards. Therefore, the reader can “simultaneously” process multiple non-contact cards. This improves the parallelism of the application and virtually increases the speed of the system.
5. It can be suitable for a variety of applications: the storage structure of the non-contact card allows it to be used for multiple purposes, and can be applied to different systems (attendance, access control, consumption, water control, electric control, etc.), and users can choose according to different applications Set different passwords and access conditions.
6. Good encryption performance: The serial number of the contactless card is unique, and the manufacturer has solidified this serial number before the product leaves the factory and cannot be changed. A two-way verification mechanism is adopted between the contactless card and the reader, that is, the reader verifies the legitimacy of the card, and the card also verifies the legitimacy of the reader. The non-contact card must be mutually authenticated with the reader three times before processing.
7. One card per person, dedicated for special cards, with extremely fast operation speed.
8. The computer automatically completes data statistics, summary, report printing, and convenient query management.
(3) Advantages of card consumption:
1. Convenience and practicality: The card automatically calculates the amount of rice sold, and the balance after deduction, saves time for finding supplements, simplifies the process of selling meals, and solves the problem of unsanitary and difficult storage of meal tickets.
2. Convenient for statistics: each window for selling meals can be automatically accumulated, and the computer control room can know the selling status of each window at any time;
3. Confidentiality and security. In addition, because the consumer machine has two screens, one side is for the operator to see if there is any misoperation, and the other is for the consumer to see if there is any error when swiping the card. Supervision can reduce disputes and create a harmonious environment.
(4) Product features:
1. There is no mechanical contact between the proximity card and the card reader, which effectively avoids various failures caused by contact reading and writing, and also avoids reading and writing failures due to harsh environments such as oil and dust;
2. The semiconductor chip is in PVC, which is dustproof, waterproof and anti-static;
3. The proximity card approaches the sensing area in any way, and the data in the card can be read within a certain distance;
4. Adopt unique anti-collision design;
5. The software is easy to operate, powerful in function, clear in software operation flow, easy to operate with online hotkey help, and complete in selling meals to meet various user needs.
6. Convenient management, whether it is an operator or a supervisor, you can query the required qualifications in real time. In addition to avoiding cash transactions to plug loopholes, management is a step up.
7. Combining catering and selling meals effectively standardizes management and reduces waste of resources.
8. Can realize the all-in-one card system.
3. The composition of IC consumption management system:
IC card, IC consumer machine (desktop or hanging), card issuer, converter, system software.
4. System performance characteristics:
1. Double-sided single-line LED digital tube display, 8 status indicators, 19 keys to touch the membrane keyboard.
2. Humanized voice alarm prompt. When encountering a card that has been reported as lost, the system will automatically send out a voice prompt such as “card has been reported as lost” to prevent audiovisual fatigue in a noisy environment (optional feature).
3. Each toll machine can store more than 26,000 consumption records.
4. Complete system functions: The system can complete various functions such as card issuance, deposit, withdrawal, statistics, inquiry, loss reporting, and reporting.
5. Multiple consumer sites are set up to facilitate centralized management and point-by-point statistics.
6. Flexible consumption method: It can realize unit price, fixed value, count and number charging method, and can set the maximum daily consumption amount and sub-consumption amount according to needs, and can implement time-limited and limited-time consumption.
