What is a Payment Gateway?

A payment gateway facilitates online credit card payment processing on your website. The software and servers transmit and authorize key information of real-time transactions to the corresponding banks, usually the acquiring and issuing banks. They are also known as merchant and customer banks. Transactional information is exchanged between both, the payment portals and processor or bank involved in the transaction. As a payment service provider, it must be secure and use encryption to store sensitive data to ensure confidential information remains safe and protected from fraudulent activities. This includes data such as credit card numbers, ACH account numbers, AVV and CVV2 numbers. Payment processing is also automated where a secure software vendor communicates with the online payment gateway and the acquiring bank. Payment gateways are necessary due to the popularity of online payments on most websites. They ensure seamless payment processing for your business, like Point-of-Sale (POS) systems in retail shops and establishments.

When the payment gateway receives the credit card details, it sends the data to the bank for verification. This information includes transaction details along with approvals or declines of a transaction. Then the payment gateway sends the received response to the user through the web server. Since security is an integral aspect of payment gateways, card associations have created a set of rules and security standards. They are called Payment Card Industry Data Security Standard (PCI-DSS or PCI) established to be followed by those with access to card information. Once a completed order is submitted usually using HTTPS protocol, it communicates personal information confidentially to the parties involved in the transaction. When a cardholder purchases a product or a service, most payment gateway providers enable added options to merchants with merchant accounts. Payment gateways can conduct real-time transactions, where providers convert currencies between two different countries, bridge language, and payment methods. Often a transaction fee is charged for using payment gateways. There are several tasks the payment gateway performs for a transaction …

What are Iframes?

An iframe or inline frame is essentially a browser window set within the web page. These frames are sections of the web page that can be ‘cut out’ to allow information from an external source. Iframes are one of the only type of frames that HTML5 allows and are usually present on websites that show external content as a feed within their web pages. Defining iframes An iframe or an inline frame is an HTML document on a website that is embedded within another HTML document. It is used to add or include content such as advertisements, interactive applications or content from other external sources into the web page. The interactive applications include those that use Asynchronous Javascript and XML such as e-commerce applications and Google maps. It is possible to configure the iframe on its own scroll bar, independent to the background page scroll bar and it behaves like an inline image. The web designer can alter the content of the iframe without the user having to reload the surrounding page. This is possible through Javascript or the HTML anchor’s target attribute. What do Iframes do? Iframes essentially allow for external content to be included within a web page. External content would consist of advertisements from advertising networks or any promotional material which is not editorial content. Using an iframe for this information is similar to having two browser windows open on the same page, where the main window shows the webpage content, and the secondary window displays the external content. The benefit here is that the actual content on the website does not get diluted because search engines do not consider these advertisements as primary content. How to use the Iframe element? A simple iframe can be built by setting the source URL, width and height. For example: <iframe src=”URL” width=”200px” height=”200px”>Alternate text if the iframe cannot be rendered </iframe>. It is also possible to use percentage instead of pixel values for the settings of the Iframe. This is useful while building a responsive website where the size changes with different screen sizes. The iframe uses HTML5 and HTML 4.01 global elements apart from others. They are as follows: URL which is the source of the frame. Name, height and width of the window. ‘srcdoc’ takes priority over any URL. It is the HTML for the source of the frame. Sandbox is the features that should be defined as …
