QR Code
A QR code (an initialism for quick response code) is a type of matrix barcode (or two-dimensional barcode) invented in 1994 by Japanese company Denso Wave. A barcode is a machine-readable optical label that can contain information about the item to which it is attached. In practice, QR codes often contain data for a locator, identifier, or tracker that points to a website or application. QR codes use four standardized encoding modes (numeric, alphanumeric, byte/binary, and kanji) to store data efficiently; extensions may also be used. The quick response system became popular outside the automotive industry due to its fast readability and greater storage capacity compared to standard UPC barcodes. Applications include product tracking, item identification, time tracking, document management, and general marketing. A QR code consists of black squares arranged in a square grid on a white background, including some fiducial markers, which can be read by an imaging device such as ...

Japanese Industrial Standards
are the standards used for industrial activities in Japan, coordinated by the Japanese Industrial Standards Committee (JISC) and published by the Japanese Standards Association (JSA). The JISC is composed of many nationwide committees and plays a vital role in standardizing activities across Japan. History In the Meiji era, private enterprises were responsible for making standards, although the Japanese government too had standards and specification documents for procurement purposes for certain articles, such as munitions. These were summarized to form an official standard, the Japanese Engineering Standard, in 1921. During World War II, simplified standards were established to increase matériel output. The present Japanese Standards Association was established in 1946, a year after Japan's defeat in World War II. The Japanese Industrial Standards Committee regulations were promulgated in 1946, and new standards were formed. The Industrial Standardization Law was enacted ...

Mobile Phone
A mobile phone, cellular phone, cell phone, cellphone, handphone, hand phone or pocket phone, sometimes shortened to simply mobile, cell, or just phone, is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN). Modern mobile telephone services use a cellular network architecture and, therefore, mobile telephones are called ''cellular telephones'' or ''cell phones'' in North America. In addition to telephony, digital mobile phones ( 2G) support a variety of other services, such as text messaging, multimedia messagIng, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, video games and digital photography. Mobile phones offering only those capabilities are known as fea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conversion Funnel
In e-commerce, the conversion funnel is the journey a consumer takes through an Internet advertising or search system, navigating an e-commerce website, and finally making a purchase. The consumer is seen as being "converted" from a visitor to the site to a buyer. A funnel describes the progressive reduction in the number of users at each stage of the process. Advertising efforts can be aimed at "upper funnel", "middle funnel", or "lower funnel" potential customers. Typically a large number of customers search for a product/service or register as page view on a referring page which is linked to the e-commerce site by a banner ad, ad network or conventional link. Only a small proportion of those seeing the advertisement or link actually click the link. The metric used to describe this ratio is the click-through rate (CTR) and represents the top level of the funnel. Typical banner and advertising click-through rates are 0.02% in late 2010 and have decreased over the past three years ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conversion Rate
In electronic commerce, conversion marketing is marketing with the intention of increasing ''conversions—''that is, site visitors who are paying customers. Measures Conversion marketing attempts to solve low online conversions through optimized customer service, which requires a complex combination of personalized customer experience management, web analytics, and the use of customer feedback to contribute to process flow improvement and site design. By focusing on improving site flow, online customer service channels, and online experience conversion marketing is commonly viewed as a long-term investment rather than a quick fix . Increased site traffic over the past 10 years has done little to increase overall conversion rates, so conversion marketing focuses not on driving additional traffic but converting existing traffic. It requires proactive engagement with consumers using real time analytics to determine if visitors are confused and show signs of abandoning the site ...

Web Browser
A web browser is application software for accessing websites. When a user requests a web page from a particular website, the browser retrieves its files from a web server and then displays the page on the user's screen. Browsers are used on a range of devices, including desktops, laptops, tablets, and smartphones. In 2020, an estimated 4.9 billion people used a browser. The most used browser is Google Chrome, with a 65% global market share on all devices, followed by Safari with 18%. A web browser is not the same thing as a search engine, though the two are often confused. A search engine is a website that provides links to other websites. However, to connect to a website's server and display its web pages, a user must have a web browser installed. In some technical contexts, browsers are referred to as user agents. Function The purpose of a web browser is to fetch content from the World Wide Web or from local storage and display it on a user's device. This process ...

Smartphone
A smartphone is a portable computer device that combines mobile telephone and computing functions into one unit. They are distinguished from feature phones by their stronger hardware capabilities and extensive mobile operating systems, which facilitate wider software, internet (including web browsing over mobile broadband), and multimedia functionality (including music, video, cameras, and gaming), alongside core phone functions such as voice calls and text messaging. Smartphones typically contain a number of metal–oxide–semiconductor (MOS) integrated circuit (IC) chips, include various sensors that can be leveraged by pre-included and third-party software (such as a magnetometer, proximity sensors, barometer, gyroscope, accelerometer and more), and support wireless communications protocols (such as Bluetooth, Wi-Fi, or satellite navigation). Early smartphones were marketed primarily towards the enterprise market, attempting to bridge the functionality of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ZXing
The application Barcode Scanner is an Android app, from the open-source project ZXing (short for Zebra Crossing), that allows an Android device with imaging hardware (a built-in camera) to scan barcodes or 2D barcodes and retrieve the data encoded. Information encoded often includes web addresses, geographical coordinates, and small pieces of text, in addition to commercial product codes. This Android-based system has similar functionality to a hardware barcode reader. This application supports many different types of barcodes, including those used to identify products in commerce. The Barcode Scanner can automatically search the Web to identify a product with a barcode and use, for example, price-comparison information between vendors. The application can decode several 2D barcodes including the widely used QR Code and Data Matrix. QR codes are often embedded in websites; Barcode Scanner can open a browser at the encoded site, for example, facilitating the download of a ...

De Facto
''De facto'' ( ; , "in fact") describes practices that exist in reality, whether or not they are officially recognized by laws or other formal norms. It is commonly used to refer to what happens in practice, in contrast with ''de jure'' ("by law"), which refers to things that happen according to official law, regardless of whether the practice exists in reality. History In jurisprudence, it mainly means "practiced, but not necessarily defined by law" or "practiced or is valid, but not officially established". Basically, this expression is opposed to the concept of "de jure" (which means "as defined by law") when it comes to law, management or technology (such as standards) in the case of creation, development or application of "without" or "against" instructions, but in accordance with "with practice". When legal situations are discussed, "de jure" means "expressed by law", while "de facto" means action or what is practiced. Similar expressions: "essentially", "unofficial", "in ...
