Question 2: What exactly does a card mean? One card really brings convenience to all of us. At least we don't have to bring so many membership cards when shopping. Oh, the day before yesterday, on New Year's Day, my fellow villagers and I went to the downtown area near us to buy clothes and new year's goods. Before going out, we all remind each other, remember, bring a membership card, or we will buy beautiful clothes or things, and we won't be able to bear the few dollars without a membership card. Think about it. If you know how to save, a dress without a membership card costs 100 yuan, and 95 yuan with a membership card can save 5 yuan. Together, I want to go back and buy at least three sets of clothes next year. A suit saves 10 yuan, and those two people can save 60 yuan. Hehe, that's right If you save this 60 yuan, you can buy another dress. Hehe, but there are so many membership cards that it's too much trouble to put them in your wallet. It's annoying to go to this store to buy. Fortunately, we went to that new clothing store and saw that they had an agent, Zhongshan Easy Search Life Card, and then I asked. Who knows, after listening to this, the old family immediately bought one from 10 yuan. You know, it's really great. You can also go to other clothes, beauty salons, Internet cafes, restaurants, and so on. There are hundreds of places where their merchants can enjoy discounts, and there are many large shopping malls we know. Although some don't know the name of the merchant, they have the address. There is a brochure with the address and telephone number of the merchant on it. You can go and see it next time you go. Maybe there are some good-looking or delicious ones.
Question 3: What is a smart card, such as a recharge card, a card that recharges multiple games, or QB, etc. . . 5 General meaning, one-card refers to the situation that many enterprises jointly launch sales, such as bus cards, a number of bus companies in a city, and bus cards are jointly sold. You can take any bus by buying a card, which is universal in the whole region! Convenient and fast,
Question 4: What does it mean to ask for coins on the bus card? Generally speaking, when you are prompted to ask for coins on the bus card, it is because there are no times and money on your card. If there are times or money, asking for money is not successful.
Bus IC card refers to integrated circuit card. It is more convenient to use a bus card. You don't need to prepare change, just swipe your card in the car. Generally speaking, it is more favorable than small change. In many places, coins cost one yuan and credit cards cost eighty cents.
Bus IC card is a non-contact data card. It changes the induced current at both ends of the coil into DC through the inductance coil on the card (the inductance coil is also a coil made of copper wire) under the action of the chip integrated in the card, and then combines a relatively large capacitor at both ends of the DC to keep the voltage at both ends stable, and then leads two wires from both ends of the coil to the chip as signal transmission lines. When approaching the card reader, the coil generates an induced voltage, which can transmit data between the card and an external database.
Question 5: What is a smart card? The most fundamental requirement of all-in-one card system is "information sharing and centralized control", so the design of the system should not be a simple combination of single functions. Consider the technical realization of the overall design ideas of software such as unified network platform, unified database, unified identity authentication system, data transmission security, various management system interfaces, exception handling, etc. The intelligent comprehensive performance of each management system and each card reading terminal equipment can achieve the best system design.
Due to the basic idea of "information sharing and centralized control", one-card is widely used in all walks of life, such as campus card, enterprise card, bank card, medical card and so on.
In May 2006, Beijing began to use the "Municipal Traffic Card". From June 65438+1 October1day, 2007, urban areas will enjoy a 40% discount and suburban areas will enjoy a 20% discount. In June 2008, 5438+ 10, all suburbs in the city were 60% off.
All-in-one card generally involves public transportation, taxis and subways, and it will also rapidly expand into gardens, highway toll collection, small consumption and other fields. At this time, the security of the data in the card, especially the wallet, is highlighted. Odd number contactless CPU card not only meets the above application requirements, but also provides a safer guarantee for the wallet in the card.
Interpretation of the concept of "one card"
In the field of smart cards, "one card" is frequently used in various card magazines, but what exactly is "one card"? What is its conceptual significance? So far there is no accurate, clear and satisfactory explanation.
At present, the concept of "all-in-one-card" should be "one card, one database and one line", that is, a network cable is connected to a database (PC), and IC card management, inquiry and other functions are realized through a comprehensive software, thus realizing the "all-in-one-card" of the whole system.
The following are explained separately:
The so-called "all-in-one card" is to realize intelligent management of many different functions on the same card. One card has many devices, not different cards have different functions, and different machines are used on different cards. Some people mistakenly think that all cards (including magnetic cards, id cards, contact ic cards, contactless IC cards, etc. ) can be read and accessed because they are all "one card" devices. The first requirement of "one card" is that the reading and writing equipment of the card must be consistent with the card. Secondly, it is required that the cards must be multi-partition and password-verified smart cards to ensure their independence, security and universality. For example, the MFARE card has 16 functional partitions with independent keys. In the M|FARE system equipment, as long as the MlFSREHHU card is empty, the password is not sealed, and the devices reach an agreement with each other, many different devices of a company can communicate with each other with one card. Different companies use the same equipment, the same card, as long as it is MFARE technology and its module system, as long as there is a blank area on the card, it can be used, which is the so-called "all-in-one card".
The so-called "one line" means that a line connects a variety of information, a variety of different devices are hung on a line, and all devices are connected in series with a PC through an interface and exchange information of different data. If there are many devices hanging on the PC, then each device will occupy a line with the PC, and the PC needs to provide it with a communication interface. In this way, there are many devices and communication interfaces, but the communication interfaces of computers are limited and cannot meet the requirements. Moreover, in the process of installation and use, it is not advisable to let so many wires communicate with PC.
The so-called "one database" is to realize card issuance, card return, loss reporting, card information inquiry and so on. In the same software, the same PC, the same database, accurate, clear, convenient and fast. This is called "one? quot。 The so-called "all-in-one card" in the market now means that all the equipment made by the company can use the company's card. As for whose database, platform and software are distributed to their respective distribution offices, this is not a real "all-in-one card". Only on the same software can the real "all-in-one card" be realized.
Structural advantages of "one card"
Because of the true meaning of "one card, one line and one library", it has the following unique advantages in structure:
1. Enjoy data * * *: speed up data exchange.
2. Comprehensive search: As there is a general database, all relevant records can be found in this database at one time as long as the query field names are given, which improves efficiency and reduces errors.
3. Comprehensive statistics: Because there is only one database, reports can be generated in time, and it is not necessary to query each PC one by one.
4. Monitor and query the usage, records and status of any terminal in real time.

Question 6: What does it mean that the ICBC card says bus card? This is a bus IC card jointly issued by ICBC and the bus company. IC card is the abbreviation of integrated circuit card, which is called microchip card, microcircuit card, smart card or smart card in some countries and regions. Bus contactless IC card is a kind of contactless IC card.
Question 7: What does the bus card mean? The group card must be a group card with more than 50 people, which is more favorable than the ordinary card.
Question 8: What does the bus card exemption form mean? It's called annual inspection, which means that every September, the student ID card and the old-age ID card prove that you are a student and old.
Question 9: What does the icdc on the bus card mean? Starting from this year, all traffic cards issued by Shanghai Communication Company have ICDC logo on the back, which is the national unified sensor chip standard. Inductive traffic cards before 2008 will be gradually replaced.
Question 10: What does "Merchants Card" mean? China Merchants Bank Card is a debit card, quasi-credit card and debit card among credit cards, which is equivalent to a savings card. You can deposit money, withdraw money, pay wages, pay telephone bills and settle accounts.
