I. Introduction
Mankind has entered the 21st century, and the entire society on which we live is facing various changes brought about by the new economic era. Since the US Vice President Al Gore proposed the concept of “digital earth” in 1998, the concept of “digital” has penetrated into all aspects, and “digital cities”, “digital communities”, and “digital homes” have also developed. Especially in recent years, the rapid development of the real estate industry and the continuous increase of people’s requirements for housing have brought the construction of “digital communities” to the agenda. Some cities have formulated plans for “digital communities”, and some cities have also built “digital communities”. Experimental engineering. So, what is a “digital community”? At present, the benevolent see benevolence, and the wise see wisdom. We believe that a “digital community” is a community that connects management and service providers with each household through 4C (computer, communication and network, automatic control, IC card) technology. The realization of the concept of digital community will enable people to live , The residential community becomes intelligent, more fulfilling and more colorful. The digital community is a key node of Unicom’s digital home and digital city, and an indispensable link in the overall project of building a “digital China”.
The state included the construction of intelligent well-off demonstration houses as an important development direction of national infrastructure investment in the “2000 Implementation Plan of the Well-off Urban and Rural Housing Technology Industry Project”, and in early 1997, it began to formulate the “Electrical Design of Well-off Housing (Standards) “Guidelines” (discussion draft), the “Guidelines” stipulate that the electrical design of a well-off residential community should meet the following requirements as a whole: a high degree of safety, a comfortable living environment, convenient communication methods, comprehensive information services, Intelligent home appliances, etc.
According to the above functional requirements, the digital community should include: community electromechanical equipment automation system, fire alarm (including gas/natural gas leak alarm) system, security monitoring system, video intercom system, parking lot management system, three-meter remote billing system, Community consumption settlement system, information network service system, community property management system, etc. Some of the systems are hardware devices and guarantees for the realization of intelligent communities, but in terms of actual use and convenience to users, the core should be the “all-in-one card” of the digital community. That is, the user can complete the usual fund settlement and certain control operations through an IC card. The implementation of the community “all-in-one card” will bring great convenience to users and will also add attractive “hot spots” to the rental and sale of the community.
It is foreseeable that the digital community is an important field of IC card applications, and it is also a new growth point driving the economic development of IC cards.
2. Application background
The first phase of Shenzhen Shekou Haiyue Garden was completed in 2001. In order to make the community management scientific, standardized, and intelligent, and to provide owners with more thoughtful and meticulous services, Shenzhen China Merchants Real Estate Co., Ltd. proposed to add IC card projects in the community, requiring the system to have The following functions:
Use Philips Mifare 1 IC card;
The IC card must have both banking functions and community functions;
With IC card access control system;
With IC card parking lot charging system;
Have IC card club consumption system;
Has the function of community bus consumption;
With member points management function;
With security patrol management;
Various products have network functions;
All data should be interacted through the network;
The system should be extensible to prepare for the interconnection between several communities in the future.
Judging from the above requirements, this is a typical digital community all-in-one card construction.
The so-called “all-in-one card” refers to how to build the application platform of the IC card as a whole, so as to bring all independent application systems into unified management. All-in-one card technology involves various aspects, such as network technology, communication technology, database technology, automatic control technology, etc., but its core is still IC card technology and reading and writing equipment. It can be said that IC cards and reading and writing equipment are the supporting points of all-in-one card technology.
In accordance with the requirements of the Ministry of Construction for the construction of digital communities, based on full discussions with Shenzhen China Merchants Real Estate, our company uses IC card technology accumulated over the years, and takes the digital community “all-in-one card” as the starting point. Together with Industrial and Commercial Bank of China, we have completed Haiyue After more than three months of trial operation, the “One Card” construction of the Garden Digital Community and the official issuance of the card in September this year have achieved remarkable results and received praise from all quarters.

(2) Function introduction
1. Card Issuing Management System
The issuance of the IC card is realized by the card issuing machine and the IC card issuance management software, and the operation is generally completed on the computer in the control center. The card issuance management system is used to realize the management of IC card personal information and consumption authority. Including personnel information entry, loss reporting and blacklist management, card renewal and card replacement, IC card data query and other functions.
The IC card is an empty card before it is issued and cannot be used. It must be issued through the system before it can be used. The issued IC card can be used for operations such as door opening, attendance, consumption, entry and exit of the parking lot, and book borrowing according to the authority. A single card realizes multiple functions, that is, the “all-in-one card”.
Haiyue Garden digital community IC card is divided into management card and community card. Management cards are provided to operators of various IC card terminals, and community cards are provided to owners.
Community cards are divided into main cards and paid cards. Each household has one main card and multiple paid cards. The main card is issued by the bank, and then initialized at the community management center, so that the main card can be used in the community, such as access control, parking, club consumption, etc., or outside the community, that is, the function of the bank card is retained, and the real realization One card with multiple functions; the payment card is issued by the community and mainly provided to the relatives of the owner. When the payment card is issued, the system will confirm the relationship with the owner and establish an internal connection between the card and the main card. All the consumption amount of the payment card is It is automatically registered to the bank account of the main card, which makes the fund management very simple and in place.
Since community IC cards are linked to bank accounts, this requires very strict measures for the management of IC cards, including administrative management and technical management. Administrative management requires that all main cards must sign an account opening agreement with the bank. Damaged or lost cards must be handled within the specified time. Technical management is the establishment of a closed-loop operating environment from the issuance of the card to the use of the card in various consumer terminals. The information on the card must be encrypted and protected, and reliable authentication must be carried out between the card and the terminal. The list mechanism can be downloaded to each terminal instantly to prevent illegal use.
2. Community consumption system
It is used for charging places such as business centers, entertainment centers, restaurants, parking lots, etc., in the community, to realize the charging of IC card holders and non-card holders from outside, and reduce unnecessary cash flow.
The community consumption system is composed of IC card consumption/charge terminal (POS), management host, IC card reader/writer, communication network and management software. Mobile POS machines (buses, activity points, etc.) adopt offline mode, and realize data upload and download between POS machines and the host through data collectors, and fixed POS machines (consumption in clubs, etc.) adopt a network connection method, and the management host summarizes each consumption in real time Point consumption data and download the consumption data in POS through the network.
The schematic diagram of the community consumption system is as follows:

3. IC card access control system
IC card access control adopts advanced computer technology, smart card technology, precision machinery manufacturing technology, etc., and uses IC card as the key to open the door, which improves the safety and reliability of the door and is the development direction of door lock control in the future. Compared with ordinary door locks, IC card access control system has the characteristics of high security, one card with multiple locks, one lock with multiple cards, one card with multiple functions, storage of card swiping records, alarm for illegal card operations, and replacement of lost cards. The IC card access control system adopts the networking mode. The networking mode can monitor the status of each unit door in real time, issue IC card numbers, extract credit card records and other functions.
4. IC card family management system
The family property management system is mainly to provide community residents with a management system for daily consumption and security of the family based on IC cards. The design of the family IC card property management system takes safety as the core and easy-to-use as the goal, providing safe and thoughtful services for the residents of the community. The family IC card property management system includes functions such as IC card to take electricity, IC card to take water, IC card to take gas, IC card to pay for cable TV, visual doorbell and closed-circuit television monitoring.
To establish a residential IC card property management system, we must first set up a toll center in the community. The center is responsible for issuing stored-value IC cards to community residents, and users can purchase a certain amount of stored-value cards according to their needs. When there is a balance in the stored-value card, the user can use electricity, water, gas, and cable television. Otherwise, it is not allowed to be used, and the IC card must be recharged at the charging center before it can be used. Adopting this method can bring the following advantages:
(1) IC card for electricity, IC card for water, IC card for gas, IC card to pay for cable TV.
(2) Users can purchase more electricity, water, gas, and cable TV fees at one time, avoiding the previous monthly separate settlement, which can save a lot of time.
(3) Water, electricity, gas, and cable television charge managers do not need to personally collect charges at residents’ homes, which not only reduces the burden on charge managers, but also avoids the possibility of bad guys pretending to be toll collectors to conduct illegal and criminal activities, making residents feel safer.
(4) It can improve the efficiency and automation of community charging management.
Residents in the community install IC card-controlled digital electricity meters, digital water meters, digital gas meters and IC card-controlled cable TV scramblers. These meters or scramblers have an IC card read-write controller. When inserting the IC stored-value card purchased from the community charging center into the read-write head of the controller, if the stored value in the card is zero, electricity, water, gas and receiving cable TV cannot be used, and the user needs to go to the community charging center After recharging, you can use electricity, water, gas, and receive cable TV.
The electricity meter, water meter, and gas meter controlled by the IC card actually use the microprocessor in the IC card controller to read the remaining amount in the IC card, and the remaining amount is zero. The electricity meter controls the relay or the water meter and gas meter control valve to make Users cannot use water, electricity and gas. The same is true for the cable TV scrambler controlled by the IC card. If the remaining amount in the IC card is zero, the TV signal will be scrambled, and the user will not be able to watch TV programs normally.
5.Patrol Subsystem
When patrolling, the sign-in form of the traditional signature book is prone to problems of counterfeiting or supplementary signing. It is time-consuming and laborious to check sign-in, and it is more difficult to analyze theft and negligence. With the advent of non-contact IC cards, an induction patrol system was naturally produced. The introduction of this system has played an extremely important role in social stability. Inductive patrols are divided into online patrols and discrete patrols. Online patrol system:
A card reader is placed at each patrol point, which is directly connected to the computer of the control management center through a cable (the principle is the same as the access control). Each patrol point is equipped with a clock, storing more than 3200 patrol records. When patrolling, as long as the patrolman puts the patrol card (inductive IC card) close to the patrol point, the card reader will automatically record the patrol number, time, location and other information. The control management center can know the patrol status of the patrol at any time.
6.Parking lot management subsystem

7. Fund settlement
A distinctive feature of the community “all-in-one card” is that it minimizes cash flow and management costs. The system automatically records the consumption status of each card consumer in the database. At regular intervals, the fund settlement data is generated and uploaded to the bank. After the bank processes the result, the result is returned. The system will process the result according to the processing result. For consumers who do not meet the consumption regulations, the system automatically treats the card as a blacklist. So that the card has no consumption rights.
There are many ways to settle with bank funds, and we adopt a batch withholding fee settlement method.
The bulk deduction fee settlement method is that the property company transfers the data of the co-branded card consumption through the IC chip to the bank, and the bank deducts the magnetic stripe account of the customer’s co-branded card in bulk through the bulk collection and payment method.
Advantages of using this method:
1. The clearing method is simple and easy to operate. The bank’s batch collection and payment clearing is a relatively mature fund settlement method, which is safe and reliable.
2. It is conducive to cost savings, no need to install other systems and networks to transmit clearing data, saving costs and expenses.
3. It is conducive to the promotion and publicity of co-branded cards. The two cards (magnetic stripe card, IC card) can be used in one account, and customers can use it without pre-charging the IC chip, which truly realizes the “all-in-one card”.
Five, concluding remarks
The implementation of the “all-in-one card” project in the digital community improves work efficiency, reduces the waste of human resources, avoids the intervention of many human factors, strengthens the orderly and effective monitoring and management of people, finances, and materials, and improves the sharing of resources Utilization rate is a good way for the digital community to move towards scientific and intelligent management. We believe that the “all-in-one card” will have a bright future in the digital community.
