Wincor Nixdorf NCR, which has English markings on these two machines, currently provides four models for ordering in the Chinese market, including NCR SelfServ 34 wall-type full-featured ATM and NCR SelfServ 32 lobby-type full-function ATM.
Functional ATMs, NCR SelfServ 25 wall-mounted ATMs and NCR SelfServ 22 lobby ATMs.
All four models feature comprehensive energy efficiency, enhanced safety and security, and strictly comply with the latest global manufacturing standards.
NCR SelfServ orders in the Asia Pacific region will be produced at NCR's ATM factory in Beijing.
1. Overview of ATM ATM ATM is the abbreviation of Automatic Teller Machine, which means automatic teller machine. Because most of them are used for withdrawing money, it is also called automatic teller machine.
It is a highly sophisticated electromechanical device that uses magnetic code cards or smart cards to implement self-service financial transactions, replacing the work of bank teller personnel.
It can withdraw cash, check deposit balances, transfer funds between accounts, balance inquiries, etc. It can also perform cash deposits (real-time entry), check deposits (not available in China), passbook replacement, intermediary services, etc.
Cardholders can use credit cards or debit cards to handle automatic withdrawals, balance inquiries, transfers, cash deposits, passbook registration, fund purchases, password changes, mobile phone bill payments and other services based on the password.
The Invention of ATM In 1939, Luther George Simjian invented the automatic teller machine.
However, the concept of an automatic teller machine in the modern sense was proposed in 1968, and the prototype appeared in 1969.
The first ATM was installed at Chemical Bank in New York.
Nowadays, ATM machines are developing very fast, and the ratio with banking institutions has reached 4:1.
The U.S. Navy even installed ATM machines on warships.
Manufacturers Main manufacturers: foreign countries include NCR, Dibao, Dry Nixdorf, Hitachi, Fujitsu, etc.
The main domestic manufacturers include: Guangdian Express, Guangzhou Yuyin, Shenzhen Southeast, etc.
2. Asynchronous Transfer Mode ATM is the abbreviation of Asynchronous Transfer Mode (ATM). ATM is a data transmission technology.
It is suitable for LAN and WAN, it has high-speed data transfer rate and supports many types of communication such as voice, data, fax, real-time video, CD-quality audio and images.
ATM is a broadband technology that transmits voice, video images and data over a LAN or WAN.
It is a cell relay technology with fixed data packet size.
You can think of a cell as a transport device that carries blocks of data from one device through an ATM switching device to another.
All cells are of the same size, unlike frame relay and LAN systems where data packets are of variable size.
Using cells of the same size provides a way to anticipate and guarantee the bandwidth required by an application.
Just as a car must wait for a long truck to turn at a busy intersection, variable-length data packets tend to cause communication delays at switching equipment.
ATM truly has the duality of circuit switching and packet switching: ATM is connection-oriented, it needs to establish a connection in both directions of communication, and then use signaling to tear down the connection after the communication is completed.
However, it abandons the synchronous time division multiplexing used in circuit switching and uses asynchronous time division multiplexing. The clocks of the sending and receiving parties can be different, which can use the bandwidth more effectively.
The transmission unit of ATM is a CELL (cell) with a fixed length of 53 bytes. The header part contains VPI/VCI information for routing selection, so it has the characteristics of switching.
It is a high-speed packet switching. In terms of protocol, it transfers the error correction and flow control functions of the third layer of OSI to intelligent terminals, which reduces network delay and increases switching speed.
Switching equipment is an important part of ATM. It can be used as a hub within an organization to quickly transmit data packets from one node to another; or as a wide area communication device to quickly transmit ATM cells between remote LANs.
Traditional LANs such as Ethernet, Fiber Distributed Data Interface (FDDI), and Token Ring use shared media. Only one node can transmit at any time, while ATM provides connections between any nodes, and the nodes can transmit at the same time.
.
Information from different nodes is multiplexed into a stream of cells.
In this system, the ATM switch can be owned by the public service provider or be part of the organization's intranet.
When used as a company's backbone network, ATM can simplify network management and eliminate many complex problems caused by network interconnections with different addressing schemes and routing mechanisms.
An ATM hub can provide connection between any two ports on the hub, regardless of the type of device connected.
The addresses of these devices are pre-mapped, making it easy, for example, to send a message from one node to another, regardless of the type of network the node is connected to.
ATM management software makes it easy for users and their physical workstations to move around.
Through ATM technology, the local area network interconnection between the corporate headquarters and various offices and company branches can be realized, thereby realizing internal data transmission, corporate email services, voice services, etc., and e-commerce and other applications can be realized through the uplink INTERNET.
