Security Printing
Security printing is the field of the printing industry that deals with the printing of items such as banknotes, cheques, passports, tamper-evident labels, security tapes, product authentication, stock certificates, postage stamps and identity cards. The main goal of security printing is to prevent forgery, tampering, or counterfeiting. More recently many of the techniques used to protect these high-value documents have become more available to commercial printers, whether they are using the more traditional offset and flexographic presses or the newer digital platforms. Businesses are protecting their lesser-value documents such as transcripts, coupons and prescription pads by incorporating some of the features listed below to ensure that they cannot be forged or that alteration of the data cannot occur undetected. A number of technical methods are used in the security printing industry. Security printing is most often done on security paper, but it can also occur on plastic m ...

Hologram
Holography is a technique that enables a wavefront to be recorded and later re-constructed. Holography is best known as a method of generating real three-dimensional images, but it also has a wide range of other applications. In principle, it is possible to make a hologram for any type of wave. A hologram is made by superimposing a second wavefront (normally called the reference beam) on the wavefront of interest, thereby generating an interference pattern which is recorded on a physical medium. When only the second wavefront illuminates the interference pattern, it is diffracted to recreate the original wavefront. Holograms can also be computer-generated by modelling the two wavefronts and adding them together digitally. The resulting digital image is then printed onto a suitable mask or film and illuminated by a suitable source to reconstruct the wavefront of interest.

Visible Spectrum
The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called '' visible light'' or simply light. A typical human eye will respond to wavelengths from about 380 to about 750 nanometers. In terms of frequency, this corresponds to a band in the vicinity of 400–790 terahertz. These boundaries are not sharply defined and may vary per individual. Under optimal conditions these limits of human perception can extend to 310 nm ( ultraviolet) and 1100 nm ( near infrared). The optical spectrum is sometimes considered to be the same as the visible spectrum, but some authors define the term more broadly, to include the ultraviolet and infrared parts of the electromagnetic spectrum as well. The spectrum does not contain all the colors that the human visual system can distinguish. '' Unsaturated colors'' such as pink, or purple variations like magenta, for examp ...

South African Reserve Bank
The South African Reserve Bank (SARB) is the central bank of South Africa. It was established in 1921 after Parliament passed an act, the "Currency and Bank Act of 10 August 1920", as a direct result of the abnormal monetary and financial conditions which World War I had brought. The SARB was only the fourth central bank established outside the United Kingdom and Europe, the others being the United States, Japan and Java. The earliest suggestions for the establishment of the Central Bank in South Africa date back to 1879. A select committee, of ten members of Parliament, was established on 31 March 1920 to examine the benefits to the national interest of the establishing of the central bank. Following on the recommendations of the committee, the South African Reserve Bank opened for business on 30 June 1921, making it the oldest central bank in Africa. The first banknotes were issued to the public by the Bank on 19 April 1922. Set of ZAR notes 2012 to present R 104 000 000 ...

Enhanced Reality
Augmented reality (AR) is an interactive experience that combines the real world and computer-generated content. The content can span multiple sensory modalities, including visual, auditory, haptic, somatosensory and olfactory. AR can be defined as a system that incorporates three basic features: a combination of real and virtual worlds, real-time interaction, and accurate 3D registration of virtual and real objects. The overlaid sensory information can be constructive (i.e. additive to the natural environment), or destructive (i.e. masking of the natural environment). This experience is seamlessly interwoven with the physical world such that it is perceived as an immersive aspect of the real environment. In this way, augmented reality alters one's ongoing perception of a real-world environment, whereas virtual reality completely replaces the user's real-world environment with a simulated one. Augmented reality is largely synonymous with mixed reality. There is also overl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malawian Kwacha
The kwacha (; ISO 4217: MWK, official name Malawi Kwacha) is the currency of Malawi as of 1971, replacing the Malawian pound. It is divided into 100 tambala. The kwacha replaced other types of currency, namely the British pound sterling, the South African rand, and the Rhodesian dollar, that had previously circulated through the Malawian economy. The exchange rate of the kwacha undergoes fixed periodical adjustments, but since 1994 the exchange rate has floated. In 2005, administrative measures were put in place by Bingu wa Mutharika to peg the exchange rate with other currencies. Banknotes are issued by the Reserve Bank of Malawi. In May 2012, the Reserve Bank of Malawi devalued the kwacha by 34% and unpegged it from the United States dollar. Etymology The name ''kwacha'' was first used in Zambia, where the Zambian kwacha was introduced in 1968. It derives from the Chinyanja or Chichewa word meaning "it has dawned", while ''tambala'' translates as "rooster" in Chichewa ...

Swiss National Bank
The Swiss National Bank (SNB; german: Schweizerische Nationalbank; french: Banque nationale suisse; it, Banca nazionale svizzera; rm, Banca naziunala svizra) is the central bank of Switzerland, responsible for the nation's monetary policy and the sole issuer of Swiss franc banknotes. The primary goal of its mandate is to ensure price stability, while taking economic developments into consideration. The SNB is an ''Aktiengesellschaft'' under special regulations and has two head offices, one in Bern and the other in Zurich. History The bank formed as a result of the need for a reduction in the number of commercial banks issuing banknotes, which numbered 53 sometime after 1826. In the 1874 revision of the Federal Constitution it was given the task to oversee laws concerning the issuing of banknotes. In 1891, the Federal Constitution was revised again to entrust the Confederation with sole rights to issue banknotes. The Swiss National Bank was founded under the law of 6 Octob ...

Mobile Device
A mobile device (or handheld computer) is a computer small enough to hold and operate in the hand. Mobile devices typically have a flat LCD or OLED screen, a touchscreen interface, and digital or physical buttons. They may also have a physical keyboard. Many such devices can connect to the Internet and connect with other devices such as car entertainment systems or headsets via Wi-Fi, Bluetooth, cellular networks or near field communication (NFC). Integrated cameras, the ability to place and receive voice and video telephone calls, video games, and Global Positioning System (GPS) capabilities are common. Power is typically provided by a lithium-ion battery. Mobile devices may run mobile operating systems that allow third-party applications to be installed and run. Early smartphones were joined in the late 2000s by larger tablets. Input and output is usually via a touch-screen interface. Phones/tablets and personal digital assistants may provide much of the functionality ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animation
Animation is a method by which still figures are manipulated to appear as moving images. In traditional animation, images are drawn or painted by hand on transparent celluloid sheets to be photographed and exhibited on film. Today, most animations are made with computer-generated imagery (CGI). Computer animation can be very detailed 3D animation, while 2D computer animation (which may have the look of traditional animation) can be used for stylistic reasons, low bandwidth, or faster real-time renderings. Other common animation methods apply a stop motion technique to two- and three-dimensional objects like paper cutouts, puppets, or clay figures. A cartoon is an animated film, usually a short film, featuring an exaggerated visual style. The style takes inspiration from comic strips, often featuring anthropomorphic animals, superheroes, or the adventures of human protagonists. Especially with animals that form a natural predator/prey relationship (e.g. cats and mice, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mobile App
A mobile application or app is a computer program or software application designed to run on a mobile device such as a phone, tablet, or watch. Mobile applications often stand in contrast to desktop applications which are designed to run on desktop computers, and web applications which run in mobile web browsers rather than directly on the mobile device. Apps were originally intended for productivity assistance such as email, calendar, and contact databases, but the public demand for apps caused rapid expansion into other areas such as mobile games, factory automation, GPS and location-based services, order-tracking, and ticket purchases, so that there are now millions of apps available. Many apps require Internet access. Apps are generally downloaded from app stores, which are a type of digital distribution platforms. The term "app", short for "application", has since become very popular; in 2010, it was listed as " Word of the Year" by the American Dialect Society. A ...
