AEPS stands for Aadhaar Enabled Payment System, a government-backed initiative launched by the National Payments Corporation of India (NPCI) that facilitates financial transactions using Aadhaar authentication. Aadhaar is a 12-digit unique identification number issued by the Unique Identification Authority of India (UIDAI) that serves as a proof of identity and address. AEPS enables individuals to carry out banking transactions without the need for a debit or credit card, or a signature.

AEPS was launched in 2016 with the aim of increasing financial inclusion in India by providing a safe, secure, and easy-to-use platform for banking services. It is particularly useful for people living in rural areas where traditional banking services may not be easily accessible. AEPS allows individuals to perform banking transactions such as balance enquiry, cash withdrawal, and funds transfer through their Aadhaar number.

How does AEPS work?

AEPS is a simple and easy-to-use platform that requires a few steps to complete transactions. Here’s how AEPS works:

1. Authentication: The first step is to authenticate the user’s identity using their Aadhaar number and biometric information (fingerprint or iris scan). This ensures that the transaction is secure and only the authorized user can perform the transaction.
2. Transaction: Once the user’s identity is authenticated, they can carry out various transactions such as cash withdrawal, balance enquiry, and funds transfer.
3. Confirmation: After the transaction is complete, the user receives a confirmation message with details of the transaction.

Features of AEPS:

1. Financial Inclusion: AEPS aims to increase financial inclusion by providing a platform that is accessible to all, including people in rural areas.
2. Safe and Secure: AEPS is a secure platform that uses Aadhaar authentication and biometric information to ensure that only the authorized user can perform the transaction.
3. Easy to use: AEPS is easy to use and requires only the user’s Aadhaar number and biometric information to carry out transactions.
4. No need for debit or credit cards: AEPS eliminates the need for debit or credit cards, making it a convenient option for people who may not have access to these cards.
5. Low transaction costs: AEPS has lower transaction costs compared to other modes of payment, making it a cost-effective option for users.

Types of Transactions that can be performed using AEPS:

1. Cash withdrawal: Users can withdraw cash from their bank account using their Aadhaar number and biometric information.
2. Balance enquiry: Users can check their account balance using their Aadhaar number and biometric information.
3. Fund transfer: Users can transfer funds from their bank account to another account using their Aadhaar number and biometric information.
4. Mini statement: Users can request a mini statement of their account using their Aadhaar number and biometric information.

Benefits of AEPS:

1. Financial Inclusion: AEPS promotes financial inclusion by providing banking services to people who may not have access to traditional banking services.
2. Secure Transactions: AEPS is a secure platform that uses Aadhaar authentication and biometric information to ensure that only the authorized user can perform the transaction.
3. Easy to use: AEPS is an easy-to-use platform that requires only the user’s Aadhaar number and biometric information to perform transactions.
4. Cost-effective: AEPS has lower transaction costs compared to other modes of payment, making it a cost-effective option for users.
5. Convenient: AEPS eliminates the need for debit or credit cards, making it a convenient option for users who may not have access to these cards.

BRICS is an acronym that stands for Brazil, Russia, India, China, and South Africa. It is a group of five emerging economies that are collectively known as the BRICS countries. The BRICS countries represent a significant share of the world’s population, land area, and economic output. The grouping was established in 2009 and has since become an important platform for the five countries to collaborate on a range of issues, including economic development, trade, and global governance.

The origins of the BRICS grouping can be traced back to a concept that was first proposed by Jim O’Neill, the former Chief Economist of Goldman Sachs. In 2001, O’Neill published a research paper titled “Building Better Global Economic BRICs” in which he identified Brazil, Russia, India, and China as four large emerging economies that had the potential to become major global players in the 21st century. According to O’Neill, the combined GDP of these four countries would overtake that of the United States by 2041.

The BRIC concept gained traction over the years, and the four countries began to meet regularly at various international forums, including the G20 and the United Nations. In 2006, they held their first formal meeting on the sidelines of the G8 summit in St. Petersburg, Russia. At that meeting, the leaders of the four countries issued a joint statement in which they called for greater cooperation and closer dialogue on global issues.

In 2009, the first BRIC summit was held in Yekaterinburg, Russia. At that meeting, the leaders of the four countries decided to formalize the grouping and to hold annual summits to discuss issues of mutual interest. The four countries also invited South Africa to join the grouping, and the name was changed to BRICS.

Since its formation, the BRICS grouping has evolved into a platform for the five countries to collaborate on a wide range of issues, including economic development, trade, energy, and global governance. The BRICS countries account for about 42% of the world’s population, 23% of global GDP, and 16% of global trade. Together, they represent a significant voice in global affairs.

The BRICS grouping has established a number of institutions to support its work, including the New Development Bank (NDB), the Contingent Reserve Arrangement (CRA), and the BRICS Business Council. The NDB is a multilateral development bank that was established to finance infrastructure and sustainable development projects in the BRICS countries and other emerging economies. The CRA is a pool of currency reserves that can be used to provide emergency funding to BRICS countries facing balance of payments crises. The BRICS Business Council is a platform for businesses in the five countries to exchange ideas and explore opportunities for collaboration.

One of the key objectives of the BRICS grouping is to promote economic development and trade among its member countries. To this end, the five countries have established a number of initiatives to promote investment and trade. In 2010, they launched the BRICS Business Forum, which brings together business leaders from the five countries to discuss issues of mutual interest. They have also established the BRICS Trade Fair, which is a platform for businesses to showcase their products and services to potential partners.

In addition to economic development, the BRICS grouping has also focused on issues of global governance. The five countries have called for a more inclusive and representative global order, and have advocated for reforms to the United Nations and other international organizations to make them more reflective of the interests of developing countries. They have also called for a greater role for developing countries in global decision-making processes.

Over the years, the BRICS grouping has faced a number of challenges. One of the key challenges has been the divergent interests of the five countries. While they

AJAX (Asynchronous JavaScript and XML) is a web development technique used to create responsive and dynamic web applications. With AJAX, web pages can update specific sections of a page asynchronously without requiring the entire page to reload. This results in a better user experience, as users can interact with web applications faster and more seamlessly.

Before AJAX, web applications relied on full page reloads to update content on the page. For example, when a user submitted a form, the entire page would reload, including the header, footer, and other content that didn’t need to change. This was a slow and inefficient way to update web pages, especially for applications that required frequent updates.

With AJAX, web developers can use JavaScript to make asynchronous requests to the server, retrieve data, and update specific sections of the page without refreshing the entire page. This technique is particularly useful for building real-time web applications that require frequent updates, such as chat applications and stock tickers.

How does AJAX work?

To understand how AJAX works, it’s important to understand the role of JavaScript, the XMLHttpRequest object, and the server in the AJAX workflow.

JavaScript

JavaScript is a programming language used to create interactive and dynamic web applications. With JavaScript, web developers can add interactivity to web pages, validate forms, and perform calculations. JavaScript is a client-side language, meaning it runs on the user’s browser, not on the server. This makes it a perfect language for creating responsive and interactive web applications.

XMLHttpRequest (XHR) object

The XMLHttpRequest (XHR) object is a built-in JavaScript object that allows web developers to make asynchronous requests to the server. With the XHR object, developers can retrieve data from the server and update the web page without reloading the entire page. The XHR object supports several request types, including GET, POST, PUT, and DELETE.

Server

The server is responsible for processing the requests made by the XHR object and returning a response. When the server receives a request, it processes the request and returns the requested data in a format such as XML, JSON, or plain text.

Here’s a step-by-step breakdown of how AJAX works:

1. User interacts with the web page

The user interacts with the web page by clicking a button, entering text into a form, or performing any other action that requires a request to the server.

2. JavaScript makes an XHR request

The JavaScript code on the web page creates an XHR object and sends a request to the server. The request can be a GET request to retrieve data from the server or a POST request to send data to the server.

3. Server processes the request

The server receives the request, processes the request, and returns a response. The response can be in the form of XML, JSON, or plain text.

4. JavaScript receives the response

The JavaScript code on the web page receives the response from the server and updates the web page dynamically. For example, if the user requested new data, the JavaScript code will add the new data to the page without refreshing the entire page.

5. Web page updates dynamically

The web page updates dynamically, without requiring a full page reload. The user can continue to interact with the page without any interruption.

Benefits of AJAX

1. Improved user experience

The most significant benefit of AJAX is that it provides a better user experience. With AJAX, web pages can update specific sections of a page asynchronously, resulting in faster and more responsive web applications. This can lead to increased user engagement and satisfaction.

2. Reduced server load

Because AJAX only retrieves and updates the necessary data, it can reduce the load on the server. This can lead to faster response times, reduced server load, and improved scalability.

3. Better SEO

With AJAX, web developers can create web applications that can be crawled by
