ISO 14443 has two variants, Type A and Type B. ISO 14443A was accepted by the ISO committee in 1997. It is the first ISO standard for 13.56 MHZ frequency contactless card which was developed by Mikron Austria and acquired by Phillips in 1996. Currently, ISO 14443A is the most widely used contactless standard in the world, mainly in transport applications. ISO 14443B was approved by the ISO committee in 1998. See similar questions...

In 1998, Philips and Texas Instruments presented ISO 15693 for vicinity applications. The aim of this standard is to increase the reading distance. Its predecessor, ISO 14443, only has a communication of 10cm, ISO 15693 expands the communication range for vicinity operations to around 1.5m in gate configuration. However, its drawback is its limited communication speed which is offset by the communication range. See similar questions...

Copies of the full ISO 14882 standard are available on line via the ISO mirror site for committee members. Non-members, or those who have not paid for the privilege of sitting on the committee and sustained their two-meeting commitment for voting rights, may get a copy of the standard from their respective national standards organization. In the USA, this national standards organization is ANSI and their website is right here. See similar questions...

Smart Cards are the latest development in card technology. They feature a silicon microchip that offers an unprecedented range of payment options and services. They possess an expandable memory capacity to enable the storage of large amounts of data on one card. Smart Cards speed up and increase the efficiency of bank transactions by storing all the necessary information. Transactions can be authorized safely even when the POS terminal is off-line.

This is the idea that a complex and autopoietic system must relate to its environment, and the internal structure becomes coupled to relevant features of that environment. In complexity terms the environment selects which of the systems attractors becomes active at any time, what is also called situated or selected self-organization. See similar questions...

TCR Engineering Services has focused on the quality assurance and quality control of our services and is proud to have successfully accredited by the National Accreditation Board of Laboratories (NABL) against the ISO / IEC 17025 standard "General Requirements for the Competence of Testing and Calibration Laboratories.

Very broadly, the UCA includes the following features that are not part of ISO 14651. This is only a sketch; for details see http://www.unicode.org/reports/tr10/. the completely ignorable characters and irrelevant combining characters don't interfere with contractions well-formedness criteria for tables (disallowing tables that would produce peculiar results, e.g. where X and Y don't contract, X < Y and yet XY == YX) [MD] See similar questions...

Even though Office Open XML was already an ECMA standard, we felt that there was value taking it on to the ISO. This was mainly because we had been asked to by various customers (mostly governments). They wanted to have our formats in the domain of the international community. See similar questions...

two cores are brought closer or the interaction distance is increased the coupling increases to a maximum of 100%, and if the fibers are matched, reduces to zero and then begins to increase again. This cyclic coupling function shows a beating of the power from one fiber to the other, the number of beats being dependent on the positioning of the cores. A 3dB, 50/50 coupler is set to mid point of the first upbeat. See similar questions...

Proximity is a new concept in card access. It is a key fob device that does not need to be swiped, just held close to the reader (thus the name "Proximity"). Proximity access control systems are economical, resistant to extreme weather conditions, vandal resistant and easy to install and maintain. The Proximity reader can be installed behind a wall so it is unobtrusive and the "keys" are seldom lost because they are kept on a key chain. See similar questions...

The V-Smart MiFare supports GemEasy 8000, HID 1430 and HID 1431 (request HID cards unprogrammed on the MIFARE? side), IDentiSMART Series by IDenticard cards. The V-Smart iCLASS supports the HID contactless smart cards [2KByte (16kBit) in both 2-application and 16-application area flavors]. See similar questions...

Smart cards feature a small embedded chip which operates as a "mini-computer" that not only securely stores data but also can process information and react to its environment. These features give smart cards the unique ability to provide secure, portable access to personalized services while protecting each user s privacy and identity. See similar questions...

The Z-card-the main processor board-can drive 80 external points. Expansion driver cards can provide 80 LED outputs per card. Up to eight expansion cards may be used with a single Z-card for a total of 640 LED outputs. If more than 640 LED outputs are required, an additional Z-card may be added. See similar questions...

Two available packages are ''defunc,'' posted to comp.sources.misc in December, 1993 (V41 i32,33), to alt.sources in January, 1994, and available from sunsite.unc.edu in pub/packages/development/libraries/defunc-1.3.tar.Z, and ''parse,'' at lamont.ldgo.columbia.edu. Other options include the S-Lang interpreter, available via anonymous ftp from amy.tch.harvard.edu in pub/slang, and the shareware Cmm (''C-minus-minus'' or ''C minus the hard stuff''). See also questions 18.16 and 20.6. See similar questions...

The most common coupling fluid in use is DI water. Other fluids can be used but chances are that they will absorb more ultrasound than water and at very high frequencies may cause poor signal levels. The instrument operator must choose a fluid that will not harm the sample or the instrument. Alcohols such as IPA are the next most common fluid. See similar questions...

All major cards offer different types of incentives, interest rates, and fee structures because they recognise that their customers use credit cards in a variety of different ways. For more information on the main differences, and how you can reach a decision on which features are of most interest to you, see our guide to choosing the right credit card which explains what to look out for in more detail.

C++ is as close as possible to compatible with C, but no closer. In practice, the major difference is that C++ requires prototypes, and that f() declares a function that takes no parameters (in C, a function declared using f() can be passed an arbitrary number of parameters of arbitrary types). There are some very subtle differences as well, like sizeof('x') is equal to sizeof(char) in C++ but is equal to sizeof(int) in C. See similar questions...
