Credit card - Wikipedia, the free encyclopedia. An example of the front in a typical credit card.
A credit card is a payment card issued to users (cardholders) as a method of payment. It allows the cardholder to pay for goods and services based on the holder's promise to pay for them. A credit card also differs from a cash card, which can be used like currency by the owner of the card. A credit card differs from a charge card also in that a credit card typically involves a third- party entity that pays the seller and is reimbursed by the buyer, whereas a charge card simply defers payment by the buyer until a later date. Technical specifications. The card number's prefix, called the Bank Identification Number, is the sequence of digits at the beginning of the number that determine the bank to which a credit card number belongs.
This is the first six digits for Master. Card and Visa cards. The next nine digits are the individual account number, and the final digit is a validity check code.
Both of these standards are maintained and further developed by ISO/IEC JTC 1/SC 1. WG 1. Credit cards have a magnetic stripe conforming to the ISO/IEC 7. Many modern credit cards have a computer chip embedded in them as a security feature. In addition to the main credit card number, credit cards also carry issue and expiration dates (given to the nearest month), as well as extra codes such as issue numbers and security codes. Not all credit cards have the same sets of extra codes nor do they use the same number of digits. History. Bellamy used the term credit card eleven times in this novel, although this referred to a card for spending a citizen's dividend from the government, rather than borrowing.
They came in various shapes and sizes; with materials made out of celluloid (an early type of plastic), copper, aluminum, steel, and other types of whitish metals. These charge coins were usually given to customers who had charge accounts in department stores, hotels, and so on.
A charge coin usually had the charge account number along with the merchant's name and logo. The charge coin offered a simple and fast way to copy a charge account number to the sales slip, by imprinting the coin onto the sales slip. This sped the process of copying, previously done by handwriting.
It also reduced the number of errors, by having a standardised form of numbers on the sales slip, instead of various kind of handwriting style. This sometimes led to a case of mistaken identity, either accidentally or intentionally, by acting on behalf of the charge account owner or out of malice to defraud both the charge account owner and the merchant. Beginning in the 1. Charga- Plate. In the 1. United States used them to sell fuel and other oil based products to a growing number of automobile owners.
It was embossed with the customer's name, city, and state. It held a small paper card on its back for a signature. In recording a purchase, the plate was laid into a recess in the imprinter, with a paper . The record of the transaction included an impression of the embossed information, made by the imprinter pressing an inked ribbon against the charge slip. In some cases, the plates were kept in the issuing store rather than held by customers.
When an authorized user made a purchase, a clerk retrieved the plate from the store's files and then processed the purchase. Charga- Plates speeded back- office bookkeeping and reduced copying errors that were done manually in paper ledgers in each store.
Air Travel Card. This is the reason the modern UATP cards still start with the number 1. With an Air Travel Card, passengers could . By the 1. 94. 0s, all of the major US airlines offered Air Travel Cards that could be used on 1. By 1. 94. 1 about half of the airlines' revenues came through the Air Travel Card agreement. The airlines had also started offering installment plans to lure new travelers into the air.
In October 1. 94.
Card reader - Wikipedia, the free encyclopedia. This article is about the hardware device. For the fortune- telling practice using a deck of cards, see Cartomancy.
A card reader is a data input device that reads data from a card- shaped storage medium. The first were punched card readers, which read the paper or cardboard punched cards that were used during the first several decades of the computer industry to store information and programs for computer systems. Modern card readers are electronic devices that can read plastic cards embedded with either a barcode, magnetic strip, computer chip or another storage medium. A memory card reader is a device used for communication with a smart card or a memory card. A magnetic card reader is a device used to read magnetic stripe cards, such as credit cards.
This model works by supplying the integrated circuit on the smart card with electricity and communicating via protocols, thereby enabling the user to read and write to a fixed address on the card. Communication protocols.
Name. Description. T=0. Asynchronous half- duplex byte- level transmission protocol, defined in ISO/IEC 7. T=1. Asynchronous half- duplex block- level transmission protocol, defined in ISO/IEC 7. T=2. Reserved for future use. T=3. Reserved for future use. Contactless. APDU transmission via contactless interface ISO/IEC 1.
If the card does not use any standard transmission protocol, but uses a custom/proprietary protocol, it has the communication protocol designation T=1. This framework works with USB devices with the specific device class 0x.
B. Readers with this class do not need device drivers when used with PC/SC- compliant operating systems, because the operating system supplies the driver by default. This allows applications to work without knowledge of the reader details. Memory card readers. Carnao Beats H.O.U.S.E Download on this page. Most card readers also offer write capability, and together with the card, this can function as a pen drive. Access control card reader.
An access control reader can be a magnetic stripe reader, a bar code reader, a proximity reader, a smart card reader, or a biometric reader. Access control readers are classified by functions they are able to perform and by identification technology: Barcode. The organization and width of the lines is determined by the bar code protocol selected. There are many different protocols, such as the prevalent Code 3. However the same affordability and simplicity makes the technology susceptible to fraud, because fake barcodes can also be created cheaply and easily, for example by photocopying real ones. One attempt to reduce fraud is to print the barcode using carbon- based ink, and then cover the bar code with a dark red overlay.
The barcode can then be read with an optical reader tuned to the infrared spectrum, but can not easily be copied by a copy machine. This does not address the ease with which barcode numbers can be generated from a computer using almost any printer.
Biometric. Biometric technology has been promoted for its ability to significantly increase the security level of systems. Proponents claim that the technology eliminates such problems as lost, stolen or loaned ID cards and forgotten PINs. If there is a high enough degree of probability that the template in the memory is compatible with the live scan (the scan belongs to the authorized person), the ID number of that person is sent to a control panel.
The control panel then checks the permission level of the user and determines whether access should be allowed. The communication between the reader and the control panel is usually transmitted using the industry standard Wiegand interface. The only exception is the intelligent biometric reader, which does not require any panels and directly controls all door hardware. Biometric templates may be stored in the memory of readers, limiting the number of users by the reader memory size (there are reader models that have been manufactured with a storage capacity of up to 5.
