Overview
Smart cards (smart IC cards), as a new information carrier, have been applied to many fields, such as hotel management, finance, access control, consumer entertainment, attendance management, communications, medical insurance, and access control industries.
“Hotel Card Management System” is based on our country’s national conditions and the development direction of modern smart buildings, combined with the actual situation of your organization, integrated hotel management software, electronic consumption, door locks, attendance management and other specific entities, drawing on smart IC cards as basic information Carrier, and successfully developed a set of computer management system.
Smart card door lock management system: The card contains the corresponding room number (it can be several rooms on the same floor or several rooms in a suite) and the door opening period. Every time the door is opened, the smart card is inserted into the door lock and the card is pulled out, and the indicator light is on Turn the handle back to open the door. Every time the door is opened, the door lock will record information including card number, date, time, room number, etc.
Smart Card Savings and Consumption Management System: When going to a restaurant to have a meal or to spend in a hotel’s hairdressing salon or sauna, you can pay with a smart IC card. The change of cash or price coupons and the staggered spread of bacteria are avoided, and the settlement is convenient, fast, and time-saving. As long as the smart IC card is inserted into the POS machine during consumption, the salesperson can deduct according to the consumption amount to complete the transaction.
Smart card attendance management system: According to the attendance system of this unit, insert the IC card into the attendance machine every time you enter and exit, the screen immediately displays the employee’s name and department, and displays “OK” to complete this attendance work. The attendance machine records the entry and exit of each employee, including card number, date, time, reason for commuting or abnormal entry and exit, etc.
System overall design
In order to realize that the three systems of hotel management door locks, electronic consumption, and personnel attendance can operate normally under the “all-in-one card” mode, all of its subsystems must be able to share data, and these are issues that must be considered in the design of this system Therefore, this chapter will be divided into five sub-sections: system design goals, system design principles, system structure, scheme design, and the realization of the “all-in-one card” system.
2.1 Design goals of the hotel card system
According to my country’s national conditions and the development direction of modern smart buildings, combined with the actual situation of your organization, comprehensive hotel management software, electronic consumption, door locks, personnel attendance and other specific entities, our system must be advanced, safe, reliable, inexpensive and practical The goal.
2.2 Design principles of the hotel card system
The system should be expandable and optimized: the entire system is an embedded design. The mature management link is in place in one step and the software and hardware construction modules can fully ensure the system expandability, and the front and back designs can be seamlessly combined.
Simple operation, easy to use, standardized management: The system management software has intuitive interface, comprehensive functions, stable performance and easy operation.
2.3 The overall structure of the hotel card system
The overall design idea of the “One Card” system is to issue a multi-partition smart IC card with encryption performance after the guest registers. The card has functions such as electronic keys, electronic wallets, and identity certification, so that guests can fully enjoy high-tech The convenience and safety brought by.

2.4 The functions of each part of the hotel card system
2.4.1 The composition of the system
The “All-in-One Card” system consists of a computer in the card issuing center, hotel management software, smart IC card door lock management equipment, attendance management equipment, and payment collection POS management equipment. The composition of the system is very flexible and convenient. It can be added or deleted at any time according to user requirements.
Smart card door lock subsystem
As a necessary equipment in hotels, door locks are getting more and more attention. Because it is not only a necessary hardware device, but also a good helper in the management of a hotel or smart building, it is also an image window of a hotel or smart building, so various door lock management systems are also launched accordingly. Looking at these door lock management systems, they can be roughly divided into two categories; one is mechanical key locks, which require a large number of waiters to be on duty and open doors for guests. This has the problem of wasting manpower and low efficiency; the other type is a variety of magnetic cards, barcode cards, and iron plate door locks. Because the door opening principle of magnetic cards, barcode cards or iron plates is simple, and the password is exposed, and the magnetic card , Barcode cards have problems such as unstable reading and writing, easy forgery, copying and unauthorized data modification.
For the above two types of locks, once the guest room is stolen or destroyed, it will bring great problems to find out the truth of the matter. Moreover, the same can not achieve versatility and multi-facetedness.
In response to the above problems, we have successfully developed a smart IC card door lock system based on the original various door locks according to the needs of users. There are corresponding room numbers in the card (it can be several rooms not on the same floor, or several inner rooms in a suite) and the door opening period. Every time the door is opened, the door will be opened by turning the handle after pulling out the card. Every time the door is opened, the door lock will record information including card number, date, time, room number, etc. This not only solves the consumption of a large amount of manpower and material resources, but also fully prevents the solution of emergencies such as theft or sabotage of guest rooms.

Smart card savings and consumption subsystem
As we all know, the current consumption methods used by domestic hotels, smart buildings, food cities and other units are actually realized in the form of price vouchers or cash. The price vouchers are mainly printed with paper, plastic and other materials, which have many disadvantages:
Fragile and breakable, it must be reprinted at regular intervals, and the repeated investment is large
Repeated circulation, unsanitary, easy to spread diseases, and serious potential adverse consequences
It is easy to forge and provides an opportunity for some criminals
Easy to lose, causing users and units to suffer economic losses
The staff has a heavy workload of selling, collecting and counting tickets, and is extremely error-prone
There are also some of the above problems in places that use cash to pay.
The biggest drawback of the above two is the inability to achieve versatility and versatility.
We have successfully developed a smart card savings and consumption management system based on the needs of users. The smart card payment POS machine can be operated as a stand-alone machine or connected to the Internet; when the user puts the smart IC card in the effective sensing area, the double-sided LED displays the operation process. At this time, the amount of money stored in the card increases with the increase in the number of consumptions. With successive deductions, consumers and operators can supervise each other during the entire operation process, and if there are errors, they can be corrected immediately. In addition, it also has automatic timing and statistics functions. The user can express the entire consumption process in the form of a report through the management software. And the machine interface is friendly, the keyboard is all Chinese characters and 0-9 Arabic numerals, easy to operate, it is a “fool-type” terminal device.

Smart Card Personnel Subsystem
As the basic management of a unit, attendance has been paid more and more attention. Therefore, various attendance management systems have been launched accordingly. Looking at these attendance management systems, they can be roughly divided into two categories: one is mechanical clocks, which rely on manual collection. Attendance records are manually summarized, which has the problem of wasting manpower and low efficiency; the other type is the attendance management of various magnetic cards and barcode cards. Because of the magnetic card, the reading and writing of the barcode card must be connected to the computer, and the magnetic card, barcode card must be connected to the computer. There are problems such as unstable reading and writing, easy forgery, and unauthorized modification of data.
In response to the above problems, our company successfully developed an IC card Chinese time and attendance machine based on the original IC card English time and attendance machine according to user needs. It integrates get off work attendance, automatic data collection, indicating alarms and other functions, which can solve a large number of personnel management The problem, leaving room for further expansion, can be used in one IC card with the management of consumption, wages, certificates, files, etc. It not only facilitates management, reduces the consumption of manpower and material resources, but also improves work efficiency and corporate image.
