It was founded in December 2015, by Sameer Nigam, Rahul Chari and Burzin Engineer. The PhonePe app, based on the Unified Payments Interface , went live in August 2016. The PhonePe app is accessible in 11 Indian languages. It enables users to perform various financial transactions such as sending and receiving money, recharging mobile and DTH, making utility payments, conducting in-store payments. PhonePe

72-1107: A computer monitor or input device, audio hardware and USB interfaces. Many servers do not have a graphical user interface (GUI). They are configured and managed remotely. Remote management can be conducted via various methods including Microsoft Management Console (MMC), PowerShell , SSH and browser-based out-of-band management systems such as Dell's iDRAC or HP's iLo . Large traditional single servers would need to be run for long periods without interruption. Availability would have to be very high, making hardware reliability and durability extremely important. Mission-critical enterprise servers would be very fault tolerant and use specialized hardware with low failure rates in order to maximize uptime . Uninterruptible power supplies might be incorporated to guard against power failure. Servers typically include hardware redundancy such as dual power supplies , RAID disk systems, and ECC memory , along with extensive pre-boot memory testing and verification. Critical components might be hot swappable , allowing technicians to replace them on

108-452: A client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers , file servers , mail servers , print servers , web servers , game servers , and application servers . Client–server systems are usually most frequently implemented by (and often identified with)

144-403: A computer program that turns a computer into a server, e.g. Windows service . Originally used as "servers serve users" (and "users use servers"), in the sense of "obey", today one often says that "servers serve data", in the same sense as "give". For instance, web servers "serve [up] web pages to users" or "service their requests". The server is part of the client–server model ; in this model,

180-521: A consumer makes a purchase at a merchant site that's set up to handle server-side digital wallets, they type their name, payment and shipping information into the merchant's own form. At the end of the purchase, the consumer is asked to sign up for a wallet of their choice by entering a user name and password for future purchases. Users can also acquire wallets at a wallet vendor's site. Most, if not all digital wallets offer advanced security features e.g. biometric authentication and encryption, this protects

216-415: A device used for (or a device dedicated to) running one or several server programs. On a network, such a device is called a host . In addition to server , the words serve and service (as verb and as noun respectively) are frequently used, though servicer and servant are not. The word service (noun) may refer to the abstract form of functionality, e.g. Web service . Alternatively, it may refer to

252-628: A digital wallet, representing a twofold increase from two years ago. A MasterCard mobile shopping survey among 8500 adults, aged 18–64 across 14 markets, showed that 45% of users in China, 36.7% of users in India and 23.3% of users in Singapore are the biggest adopters of digital wallets. The survey was conducted between October and December 2015. Further analysis showed that 48.5% of consumers in these regions made purchases using smartphones. Indian consumers are leading

288-411: A server serves data for clients . The nature of communication between a client and server is request and response . This is in contrast with peer-to-peer model in which the relationship is on-demand reciprocation. In principle, any computerized process that can be used or called by another process (particularly remotely, particularly to share a resource) is a server, and the calling process or processes

324-423: A service for the requester, which often runs on a computer other than the one on which the server runs. The average utilization of a server in the early 2000s was 5 to 15%, but with the adoption of virtualization this figure started to increase to reduce the number of servers needed. Strictly speaking, the term server refers to a computer program or process (running program). Through metonymy , it refers to

360-711: A thin wallet, is one that an organization creates for and about you and maintains on its servers . Server-side digital wallets are gaining popularity among major retailers due to the security, efficiency, and added utility it provides to the end-user, which increases their satisfaction of their overall purchase. The information component is basically a database of user-input information. This information consists of your shipping address, billing address, payment methods (including credit card numbers, expiry dates, and security numbers), and other information. Digital wallets are composed of both digital wallet devices and digital wallet systems. There are dedicated digital wallet devices such as

396-406: Is a client. Thus any general-purpose computer connected to a network can host servers. For example, if files on a device are shared by some process, that process is a file server . Similarly, web server software can run on any capable computer, and so a laptop or a personal computer can host a web server. While request–response is the most common client-server design, there are others, such as

432-618: Is a collaborative effort, Open Compute Project around this concept. A class of small specialist servers called network appliances are generally at the low end of the scale, often being smaller than common desktop computers. A mobile server has a portable form factor, e.g. a laptop . In contrast to large data centers or rack servers, the mobile server is designed for on-the-road or ad hoc deployment into emergency, disaster or temporary environments where traditional servers are not feasible due to their power requirements, size, and deployment time. The main beneficiaries of so-called "server on

468-515: Is a digital wallet where private keys are stored for cryptocurrencies like bitcoin . A digital wallet has both a software and information component. Secure and fair electronic payment systems are an important issue. The software provides security and encryption for the personal information and for the actual transaction. Typically, digital wallets are stored on the client side and are easily self-maintained and fully compatible with most e-commerce websites. A server-side digital wallet, also known as

504-427: Is also less of a concern, but power consumption and heat output can be a serious issue. Server rooms are equipped with air conditioning devices. A server farm or server cluster is a collection of computer servers maintained by an organization to supply server functionality far beyond the capability of a single device. Modern data centers are now often built of very large clusters of much simpler servers, and there

540-509: Is automatically updated and entered into the order fields across merchant sites when using a digital wallet. Consumers also benefit when using digital wallets because their information is encrypted or protected by a private software code; merchants benefit by receiving a combination of protection against fraud, faster receipt of payment, decreased transaction costs, and decreased theft loss. Digital wallets are available to consumers free of charge, and they're fairly easy to obtain. For example, when

576-405: Is contrasted with "user", distinguishing two types of host : "server-host" and "user-host". The use of "serving" also dates to early documents, such as RFC 4, contrasting "serving-host" with "using-host". The Jargon File defines server in the common sense of a process performing service for requests, usually remote, with the 1981 version reading: SERVER n. A kind of DAEMON which performs

612-694: The Internet is based upon a client–server model. High-level root nameservers , DNS , and routers direct the traffic on the internet. There are millions of servers connected to the Internet, running continuously throughout the world and virtually every action taken by an ordinary Internet user requires one or more interactions with one or more servers. There are exceptions that do not use dedicated servers; for example, peer-to-peer file sharing and some implementations of telephony (e.g. pre-Microsoft Skype ). Hardware requirement for servers vary widely, depending on

648-512: The NPCI guidelines. Initially, on 19 January 2017, NPCI instructed ICICI to allow UPI transactions via PhonePe. During this period, Airtel too blocked PhonePe transactions on its platforms. A day later, on 20 January 2017, NPCI renounced the previous instructions citing the reason that PhonePe indeed violated the UPI norms. After this, PhonePe closed its operations on Flipkart's website, to align itself with

684-409: The publish–subscribe pattern . In the publish-subscribe pattern, clients register with a pub-sub server, subscribing to specified types of messages; this initial registration may be done by request-response. Thereafter, the pub-sub server forwards matching messages to the clients without any further requests: the server pushes messages to the client, rather than the client pulling messages from

720-514: The request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledgment. Designating a computer as "server-class hardware" implies that it is specialized for running servers on it. This often implies that it is more powerful and reliable than standard personal computers , but alternatively, large computing clusters may be composed of many relatively simple, replaceable server components. The use of

756-847: The Internet, the dominant operating systems among servers are UNIX-like open-source distributions , such as those based on Linux and FreeBSD , with Windows Server also having a significant share. Proprietary operating systems such as z/OS and macOS Server are also deployed, but in much smaller numbers. Servers that run Linux are commonly used as Webservers or Databanks. Windows Servers are used for Networks that are made out of Windows Clients. Specialist server-oriented operating systems have traditionally had features such as: In practice, today many desktop and server operating systems share similar code bases , differing mostly in configuration. In 2010, data centers (servers, cooling, and other electrical infrastructure) were responsible for 1.1–1.5% of electrical energy consumption worldwide and 1.7–2.2% in

828-592: The United States. One estimate is that total energy consumption for information and communications technology saves more than 5 times its carbon footprint in the rest of the economy by increasing efficiency. Global energy consumption is increasing due to the increasing demand of data and bandwidth. Natural Resources Defense Council (NRDC) states that data centers used 91 billion kilowatt hours (kWh) electrical energy in 2013 which accounts to 3% of global electricity usage. Environmental groups have placed focus on

864-475: The biometric wallet by Dunhill , a physical device that holds cash and cards along with a Bluetooth mobile connection. Presently there are further explorations for smartphones with NFC digital wallet capabilities, such as smartphones utilizing Google's Android and Apple's iOS operating systems to power wallets such as Google Pay and Apple Pay . Digital wallet systems enable the widespread use of digital wallet transactions among various retail vendors in

900-578: The financial information of the users thus preventing fraud. With the acquisition of iDEAL , European Payments Initiative (EPI) Company has announced that it will create an all European digital wallet. Server (computing) A server is a computer that provides information to other computers called " clients " on a computer network . This architecture is called the client–server model . Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients or performing computations for

936-577: The form of mobile payments systems and digital wallet applications. The M-PESA mobile payments system and microfinancing service has widespread use in Kenya and Tanzania , while the MasterCard PayPass application has been adopted by a number of vendors in the U.S. and worldwide. Digital wallets are being used more frequently among Asian countries as well. One in every five consumers in Asia are now using

972-411: The go" technology include network managers, software or database developers, training centers, military personnel, law enforcement, forensics, emergency relief groups, and service organizations. To facilitate portability, features such as the keyboard , display , battery ( uninterruptible power supply , to provide power redundancy in case of failure), and mouse are all integrated into the chassis. On

1008-531: The holder's credentials. For example, a digital wallet could verify the age of the buyer to the store while purchasing alcohol. The system has already gained popularity in Japan, where digital wallets are known as "wallet mobiles". In addition, a few US states have adapted digital driver's license and state IDs to be added to digital wallet in lieu of the physical card and it can be used at selected TSA checkpoints at airports, banking or enterprise. A cryptocurrency wallet

1044-564: The running server without shutting it down, and to guard against overheating, servers might have more powerful fans or use water cooling . They will often be able to be configured, powered up and down, or rebooted remotely, using out-of-band management , typically based on IPMI . Server casings are usually flat and wide , and designed to be rack-mounted, either on 19-inch racks or on Open Racks . These types of servers are often housed in dedicated data centers . These will normally have very stable power and Internet and increased security. Noise

1080-411: The server as in request-response. The role of a server is to share data as well as to share resources and distribute work. A server computer can serve its own computer programs as well; depending on the scenario, this could be part of a quid pro quo transaction, or simply a technical possibility. The following table shows several scenarios in which a server is used. Almost the entire structure of

1116-412: The server's purpose and its software. Servers often are more powerful and expensive than the clients that connect to them. The name server is used both for the hardware and software pieces. For the hardware servers, it is usually limited to mean the high-end machines although software servers can run on a variety of hardwares. Since servers are usually accessed over a network, many run unattended without

This has inspired companies like Reliance and Amazon India to come out with their own digital wallet. Flipkart has already introduced its own digital wallet. Consumers are not required to fill out order forms on each site when they purchase an item because the information has already been stored and

1224-565: The word server in computing comes from queueing theory , where it dates to the mid 20th century, being notably used in Kendall (1953) (along with "service"), the paper that introduced Kendall's notation . In earlier papers, such as the Erlang (1909) , more concrete terms such as "[telephone] operators" are used. In computing, "server" dates at least to RFC 5 (1969), one of the earliest documents describing ARPANET (the predecessor of Internet ), and
