Micropayment
A micropayment is a financial transaction involving a very small sum of money and usually one that occurs online. A number of micropayment systems were proposed and developed in the mid-to-late 1990s, all of which were ultimately unsuccessful. A second generation of micropayment systems emerged in the 2010s. While micropayments were originally envisioned to involve very small sums of money, practical systems to allow transactions of less than 1 have seen little success. One problem that has prevented the emergence of micropayment systems is a need to keep costs for individual transactions low, which is impractical when transacting such small sums even if the transaction fee is just a few cents. Definition There are a number of different definitions of what constitutes a micropayment. PayPal defines a micropayment as a transaction of less than £5 while Visa defines it as a transaction under 20 Australian dollars. History The term was coined by Ted Nelson, long before the invent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zong Mobile Payments
Zong was a mobile payment company that allowed users to make micropayments on the Internet if they have a postpaid mobile phone. The payments were charged to their mobile phone bills by the mobile operator. The company was acquired by eBay in 2011. Zong payments were only accepted by online games and social networks, and the service can be used to purchase virtual goods. Zong was awarded the 2009 Frost & Sullivan Best Practices Award for New Product Innovation in the Mobile Payments category. In May 2015, Zong disappeared from the web without any public declaration. The website now simply redirects to PayPal.

List Of HTTP Status Codes
This is a list of Hypertext Transfer Protocol (HTTP) response status codes. Status codes are issued by a server in response to a client's request made to the server. It includes codes from IETF Request for Comments (RFCs), other specifications, and some additional codes used in some common applications of the HTTP. The first digit of the status code specifies one of five standard classes of responses. The optional message phrases shown are typical, but any human-readable alternative may be provided, or none at all. Unless otherwise stated, the status code is part of the HTTP standard (). The Internet Assigned Numbers Authority (IANA) maintains the official registry of HTTP status codes. All HTTP response status codes are separated into five classes or categories. The first digit of the status code defines the class of response, while the last two digits do not have any classifying or categorization role. There are five classes defined by the standard: * ''1xx informational re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Financial Transaction
A financial transaction is an Contract, agreement, or communication, between a buyer and seller to exchange goods, Service (economics), services, or Asset, assets for payment. Any transaction involves a change in the status of the finances of two or more businesses or individuals.

Most purchases are made with cash payments, including Cash, physical currency, Debit card, debit cards, or Cheque, cheques. The other main form of payment is credit, which gives immediate access to funds in exchange for repayment at a later date. History There is no evidence to support the theory that ancient civilizations worked on systems of barter. Instead, most historians believe that ancient ...

Symmetric Cryptography
Symmetric-key algorithms are algorithms for cryptography that use the same cryptographic keys for both the encryption of plaintext and the decryption of ciphertext. The keys may be identical, or there may be a simple transformation to go between the two keys. The keys, in practice, represent a shared secret between two or more parties that can be used to maintain a private information link. The requirement that both parties have access to the secret key is one of the main drawbacks of symmetric-key encryption, in comparison to public-key encryption (also known as asymmetric-key encryption). However, symmetric-key encryption algorithms are usually better for bulk encryption. They have a smaller key size, which means less storage space and faster transmission. Due to this, asymmetric-key encryption is often used to exchange the secret key for symmetric-key encryption. Types Symmetric-key encryption can use either stream ciphers or block ciphers. * Stream ciphers encrypt the digi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nieman Foundation For Journalism
The Nieman Foundation for Journalism at Harvard University is the primary journalism institution at Harvard. It was founded in February 1938 as the result of a $1.4 million bequest by Agnes Wahl Nieman, the widow of Lucius W. Nieman, founder of ''The Milwaukee Journal''. Scholarships were established for journalists with at least three years' experience to go back to college to advance their work. She stated the goal was "to promote and elevate the standards of journalism in the United States and educate persons deemed specially qualified for journalism." It is based at Walter Lippmann House in Cambridge, Massachusetts.

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 the 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 s ...
