Short codes (also known as short numbers) are special telephone numbers, significantly shorter than full telephone numbers, that can be used to address SMS and MMS messages from certain service provider’s mobile phones or fixed phones. There are two types of short codes: dialing and messaging.
Short codes are designed to be easier to read and remember than normal telephone numbers. Like telephone numbers, short codes are unique to each operator at the technological level. Even so, providers generally have agreements to avoid overlaps. In some countries, such as the United States, some classes of numbers are inter-operator (U.S. inter-operator numbers are called common short codes).
Short codes are widely used for value-added services such as television program voting, ordering ringtones, charity donations and mobile services. Messages sent to short code can be billed at a higher rate than a standard SMS and may even subscribe a customer to a recurring monthly service that will be added to their mobile phone bill until they text, for example, the word “STOP” to terminate the service.
[WAP is] the de facto worldwide standard for providing Internet communications and advanced telephony services on digital mobile phones, pagers, personal digital assistants and other wireless terminals – WAP Forum
WAP stands for Wireless Application Protocol. Per the dictionary definition for each of these words, we have:
Wireless: Lacking or not requiring a wire or wires: pertaining to radio transmission.
Application: A computer program or piece of computer software that is designed to do a specific task.
Protocol: A set of technical rules about how information should be transmitted and received using computers.
WAP is the set of rules governing the transmission and reception of data by computer applications on, or via, wireless devices like mobile phones. WAP allows wireless devices to view specifically designed pages from the Internet, using only plain text and very simple black-and-white pictures.
WAP is a standardized technology for cross-platform, distributed computing, very similar to the Internet’s combination of Hypertext Markup Language (HTML) and Hypertext Transfer Protocol (HTTP), except that it is optimized for:
Low-display capability
Low-memory
Low-bandwidth devices, such as personal digital assistants (PDAs), wireless phones, and pagers.
WAP is designed to scale across a broad range of wireless networks, like GSM, IS-95, IS-136 and PDC.A QR code (abbreviated from Quick Response code) is a type of matrix barcode (or two-dimensional code) first designed for the automotive industry. More recently, the system has become popular outside of the industry due to its fast readability and comparatively large storage capacity. The code consists of black modules arranged in a square pattern on a white background. The information encoded can be made up of four standardized kinds (“modes”) of data (numeric, alphanumeric, byte/binary, Kanji), or by supported extensions virtually any kind of data.
