Is one card virtual currency

1. No,
virtual currency refers to non real currency. Well known virtual currencies, such as online currency of Internet company, q-coin of Tencent company, q-point and voucher of Shanda company, micro currency launched by Sina (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), silver grain (used for bixue Qingtian game), and popular digital currencies in 2013 include bitcoin, Laite coin, infinite coin, quark coin, zeta coin, etc Barbecue coins, pennies (Internet), invisible gold bars, red coins, prime coins. At present, hundreds of digital currencies are issued all over the world. Popular in the circle & quot; The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum".

2.

1. Q coin

Q coin, referred to as QB, also known as QQ coin, Tencent Q coin, etc. Usually its exchange rate is 1q currency = 1 RMB, with Tencent paipai net transactions are generally 10% off

QB is a virtual currency launched by Tencent, which can be used to pay for QQ bank number, QQ member service and other services. Tencent q-coin, through the purchase of QQ card, telephone recharge, bank card recharge, network recharge, mobile phone recharge card, one card recharge card and other ways to obtain

The face value of QQ card is 10 yuan, 15 yuan, 30 yuan, 60 yuan, 100 yuan and 200 yuan respectively

there is another kind of electronic cryptocurrency, qqcoin, which is not related to each other

2. Litecoin

litecoin, abbreviated as LTC, currency symbol: Ł; It is a kind of network currency based on "peer-to-peer" technology. It is also an open source software project under MIT / X11 license. It can help users make instant payments to anyone in the world

lightcoin is inspired by bitcoin (BTC) and has the same implementation principle in technology. The creation and transfer of lightcoin is based on an open source encryption protocol and is not managed by any central organization

3, infinite coin

infinite coin (hereinafter referred to as IFC) is a new digital currency, which has more circulation advantages than bitcoin, and fills the short board of bitcoin in the field of commercial circulation and promoting commercial operation. The positioning of unlimited money is to serve the daily life of small transaction payment

one transaction of infinite coin needs three confirmations, each confirmation takes three seconds, and the transaction confirmation speed is very fast. Because bitcoin transaction needs 6 confirmations, which takes about 1 hour, and lightcoin transaction takes 15 minutes, infinite coin is used in daily common transactions, which is more practical

infinite coin was released on June 5, 2013. Based on scrypt POW algorithm. A block is generated in 30 seconds. In the initial block, there are 524288 infinite coins in each block. After that, for every 86400 blocks generated, the number of coins in the block is halved, with a total of 90.6 billion. The difficulty of mining is adjusted every hour

Quark coin is not the currency in real life, it exists safely in the computer of global network

quark network is protected by six most advanced encryption algorithms to ensure that it can become a digital ledger. The whole network uses each of the six functions to generate a proof of work, and the coin maker must "verify" these transactions to ensure that each coin increase is real and effective

only regular computer can participate in ensuring that it can maintain a highly secure peer-to-peer network, which makes it more decentralized

quark coins can only be g up through the CPU of regular computers. In the first 36 weeks, a total of 247605120 quark coins will be g out. Since March 30, 2014, the annual quark coins set at 1050000 can enter the market through "digging", and the block reward will never be less than one, which is currently two

Zetacoin is an open-source digital currency based on SHA-256 algorithm. The initial coin mining is 160 million coins, and the subsequent annual inflation is a better incentive, To keep the hash of the network is not pure transaction cost

The total number of

zetacoin is 160 million, 1000 zets per block and half of 80640 zets per block

3. Electronic currency belongs to virtual currency, but virtual currency is not necessarily electronic currency. In the mainstream currency circle, it is generally called digital currency rather than virtual currency. Virtual currency is just a name that does not know much about digital currency
digital currency has made great progress in China, and the central bank version of digital currency has come out, which will first be applied to the bill market. The domestic Puyin group has launched the tea based digital currency Puyin, which has the credit endorsement of tea assets.

4. Yes
for example, the current electronic transfer is actually virtual currency
of course, paper money itself is a currency symbol, not a currency
the goods ratio is the general equivalent
nowadays, paper money or virtual currency are all transactions based on national credit or enterprise credit
in these economic activities, virtual currency acts as a measure of value and a means of circulation.

5. The time badge is just a prop
and you are wrong. RMB can't buy the badge directly. RMB can buy the badge by replacing it with battle net points

6. Not really! Money needs to circulate, and this can only be regarded as an ancient silver note, just for the convenience of use, or to say... It can only be consumed on campus, can't be traded, and at most has something to do with virtual money...

7. If it is the all-in-one card of China Merchants Bank, the "all-in-one card" is the debit card of China Merchants Bank, which is usually called the savings card. It needs to deposit before use, and has no function of overdraft and cash advance
it is a card with comprehensive financial management function, which integrates current, fixed, multi currency in one card, and has the functions of ATM deposit and withdrawal, card consumption, payment transfer, online payment, etc

8.

The so-called "all-in-one card" is to realize the intelligent management of many different functions on the same card. In essence, it is a special information management system composed of card, appliance and upper management software. Its core content is to realize the standardization and automation of information resource management from business data generation, collection, transmission to summary and analysis by using card as a specific physical medium. At the same time, as a part of enterprise information management, enterprise card is closely related to ERP system, financial system and HR system

extended data

according to the media of all-in-one card, it can be divided into read-only type and read-write type. Read only all-in-one card generally uses the ID number on the card to realize identity authentication, and carries out data interaction in the background, such as magnetic stripe card, bar code card, PVC card with ID number, non-contact IC card (RFID RF card). Read write all-in-one card is widely used. The card can be used as identity authentication ID or card writing operation. Read write card, i.e. IC card, can be divided into contact type and non-contact type. Non contact type is the mainstream today and in the future. Contactless IC card is a radio frequency (RFIC) card, which has a built-in chip. Taking Philips Mifare card as an example, it is composed of multiple read-write sectors, which can be encrypted, stored, read and rewritten. Today's RF card technology developed to CPU card stage, in addition to encryption, storage, reading, rewriting, and has the function of operation and dynamic encryption. CPU card is the mainstream in the future. The mobile phone SIM / UIM card and RF technology are integrated to form a new medium, namely mobile phone card

9. The most fundamental requirement of the all-in-one card system is "information sharing and centralized control". Therefore, the design of the system should not be a simple combination of indivial functions. Considering 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., all management systems should be integrated, The overall performance of the card reading terminal equipment is intelligent to achieve the best system design
e to the basic idea of "information sharing and centralized control", one card is widely used in all walks of life, such as campus one card, enterprise one card, bank school one card, medical one card and so on
in May 2006, Beijing began to use the "municipal transportation card". Starting from January 1, 2007, 40% discount will be given for bus in urban areas and 20% discount will be given for suburban areas. In January 2008, the urban and suburban areas were all given a 40% discount
the all-in-one card generally involves public transportation, taxi and subway, and also rapidly expands to the fields of garden, highway toll, small consumption, etc. At this time, the security of the data in the card, especially the wallet, is highlighted. In addition to meeting the above application requirements, the contactless CPU card also provides a more secure protection for the wallet in the card
"one card" concept interpretation
in the field of smart card, in various card magazines, "one card" is used more frequently, but what is "one card"? What is its conceptual meaning? So far, there is no accurate, clear and satisfactory explanation
at present, the concept of "all in one card" should be "one card, one library, one line", that is, a network line is connected to a database (PC), and through a comprehensive software, the functions of IC card management and query can be set, so as to realize the "all in one card" of the whole system
the following are explained respectively:
the so-called "one card" is to realize the intelligent management of multiple different functions on the same card. There are many devices on one card, not different cards with different functions, and different computers are used on different cards. Some people mistakenly believe that since it is "all-in-one card" &;, Equipment, then all cards (including magnetic card, LD card, contact IC card, non-contact IC card, etc.) can read and pass“ All in one card;, The first requirement is that the read-write device of the card must be consistent with the card. Secondly, the card must be a smart card with multi partition and password verification to ensure their independence, security and versatility. For example, mfare card has 16 functional partitions with independent keys. In M | fire system equipment, as long as mlfsrehhu card has a vacant space and does not seal the password, and each device has a good agreement with each other, multiple different devices of a company can be connected with one card. Different companies use the same kind of equipment, the same card, as long as it is mfare technology, and its mole system, as long as the card has an empty area, it can be used. This is the so-called "one card"
the so-called "one line" refers to a line connecting multiple kinds of information. A variety of different devices are hung on one line, and all devices are connected together through one line and an interface with PC to exchange information of different data. If a lot of devices are hung on the PC, then each device and the PC occupy a line, and the PC needs to provide it with communication interface. In this way, there are many devices and communication interfaces, but the communication interface of the computer is limited, which can not meet the requirements. Moreover, in the process of installation and use, it is not advisable to connect so many lines with the PC
the so-called "one database" is to realize card issuing, card cancellation, card loss reporting and card data query in the same software, PC and database, which is accurate, clear, convenient and fast. It's called "one? quot; Now, the so-called "all-in-one card" in the market means that all devices made by the company can use the company card. As for whose database, whose platform and whose software will be issued at their respective distribution offices, this is not a real "all-in-one card". Only on the same software can we achieve a real "all-in-one card"
"one card" structure advantages
because the real meaning of "one card, one line, one library", it shows the following unique advantages in structure:
1. Data sharing: speeds up the speed of data exchange
2. Comprehensive search: because there is a general database, as long as the query field name is given, all relevant records can be found in this database at one time, so as to improve efficiency and rece errors
3. Comprehensive statistics: since there is only one database, the report can be generated in time, and it is unnecessary to query each PC one by one
4. Real time monitor and query the usage and record of any terminal
5. Simple operation: only once, at most two steps, the function can be realized without multiple conversions
6. Rece equipment investment and cost< In addition, e to the versatility and compatibility of the card, the chip of mfare card can be divided into 16 regions, and each region can be set with its own regional password. The security, reliability and independence of mfare card can be extended to the following features:
1
2. The software is different, but it can be shared in different areas: under different software, the function can still occupy different areas, and the encryption function can be used independently without interference
for example: in a residential area, Xian'an armored company's "all-in-one card" equipment can realize five functions. When issuing a special IC card, it occupies five areas in the card and encrypts them. Later, company B installs terminal equipment proced by company B in the residential area, which can realize three functions with IC card. In this case, we can take advantage of the chip of | c card to replace the | c card issued by company A, Then, it will be released under the software of company B, occupying three areas other than 5 / 16, and encrypted, and so on, until all areas are occupied by the release. In the future, this IC card can be used to pass through the terminal equipment of company a and company B to realize "one card"< With the popularization and application of science and technology, many departments of almost every instry in modern society have called in IC card intelligent management system. According to the current market situation, the accurate and effective "all-in-one card" management system is established;, It has become the "inevitable outcome of potential";, It is the inevitable requirement of the market. As a result, regardless of business card printing companies, chip suppliers, system integrators, applications, have launched a "one card."
in fact, what people in the instry call "all in one card" is just a proct of a combination of single functions in a broad sense. For example, a manufacturer proces indivial intelligent systems such as access control, parking lot and patrol, which have their own independent equipment and software. Under the market trend, the manufacturer combines these systems and installs them in a certain area. Because it is a | c card, it is called "all in one card". Its network is as follows:
this so-called "all in one card" &;, It has the following shortcomings:
(1) multiple software and multiple distribution systems: if you want to realize one card access, you need to issue this card one by one in each system, which is equivalent to notifying each software one by one, and this card can be used. Tedious and inefficient
(2) multiple databases, multiple PCs (i.e. computers): if you want to query the consumption records of an IC card, you can only enter the card number one by one on each PC and database, and then make statistics. Time consuming and inconvenient< (3) without shared database, it is impossible to realize the one-time and easy operation function of total statistics and total retrieval< (4) high cost and complicated operation
to sum up, this kind of "all-in-one card" is not accurate, high cost, high cost, and slow data running speed, which can only be regarded as not really realizing "all-in-one card";, A transition before a software function
hardware and software conditions for "one card" implementation
as an inevitable trend in the development of smart card field, "one card" is a complex and exquisite system application project. Its hardware and software must meet certain conditions and standards, otherwise it is difficult to achieve "one card" in the true sense
first of all, it is necessary to make "all in one card";, This kind of card must be a smart card with multi partition, password verification, multi-purpose, compatibility, security and reliability, which is the precondition of "one card". Now there are many kinds of cards on the market, from the early barcode card and magnetic card to the contact | c card, then to the non-contact | c card and smart card, which are developing rapidly and becoming more and more advanced. Simple structure, read-only, no write, no area, no anti-counterfeiting, no multi-purpose cards, such as bar code card, magnetic card, | D card and some cards without CPU function can not be used as "all-in-one card";, Here is a brief introction to the types and characteristics of smart cards, The advantages and disadvantages are as follows:
smart card types:
1. Encrypted memory card (security cards contact type)
2. Unencrypted memory card (memory cards contact type)
3. Prepaid card (contact type)
4. CPU card (smart cards contact type)
5. RF encryption card (rf1d contact type)
6. RF CPU card (RFID contact type)
7. P IC card (parallel communication IC card)
5 />Features:
1. Anti destructive and rability:
the smart card is made of silicon chip to store information. The advanced silicon chip manufacturing process can fully guarantee the card's anti-magnetic, static and various ray capabilities. Moreover, e to the small size of the silicon chip, the inside is protected by epoxy layer, and the outside is protected by PCB board and substrate, so it has strong mechanical and chemical resistance. All of these are specified in is07816-1. Now the smart card has been made very delicate and rable. The storage period of information is more than 100 years, and it is easy to read and write. The number of times of reading and writing is more than 100000. Even considering a variety of factors, a smart card can be used for at least 10 years
2. Storage capacity and flexibility:
the capacity of smart card can be several dry bytes, and the storage area on smart card can be divided, which can have different access levels, which provides convenience for information processing and multi-purpose of one card
3. Encryption:
the smart card system has strong encryption, which is first reflected in the chip structure and reading mode. The smart card has large capacity, and the read and write areas of the memory can be selected at will. Therefore, it has great flexibility, even if the general memory card adopts specific technology, it also has strong confidentiality. For the encrypted memory card, there is a strict limit on the number of times to check the card password. If the number exceeds the specified number, the card will be locked. The encryption of the smart card is also reflected in the system design. Because the smart card is a portable digital circuit, and various hardware encryption means of the digital circuit can be used to improve the encryption of the system. In addition, in the software design, various encryption algorithms can be used to greatly enhance the security of the system
the above is a superficial view on the concept and application of "all in one card". I believe that the application of intelligent "all in one card" will be more practical and perfect
"one card for all" and "one card for all" have become the application themes of smart cards. As one of the largest IC card application fields in China, urban construction card involves many fields, such as urban public transportation, subway, taxi, road and Bridge toll, water supply, gas supply, heat supply, residential area and so on. TimeCOS / DI is the smart card that meets the application requirements
when the smart card is used in the bank, it can be inserted into the card reader to complete the banking business. At the same time, when the bus or taxi is in use, it is not necessary to insert the card into the card reader, just shake the card on the card reader with wireless sensing area, which is very time-saving. Therefore, in city life, as long as there is a & quot; All in one card;, You can make a phone call, take a bus, take a taxi, go shopping, pay for water and electricity, and save money

10. The debit card issued by China Merchants Bank is called "all-in-one card" (i.e. savings card, which needs to deposit before use, and has no overdraft function). It must open an account with real name (real name system). It has multiple currencies and multiple savings in one. It also has the functions of ATM deposit and withdrawal, POS card consumption, transfer remittance, online payment, etc. it is a card with comprehensive financial management function. One net user is a comprehensive management account launched by China Merchants Bank, which can be bound with one card and credit card under its own name. Just login name and password, you can login in our bank's public version, mobile banking, credit card palm life and other channels to manage the associated card information. It is more convenient to login without using the card number and password.
