ISO/IEC was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 17, Cards and personal identification. ISO/IEC , is an ISO standard for vicinity cards, i.e. cards which can be read from a greater ISO/IEC Identification cards — Contactless integrated circuit cards — Vicinity cards — Part 2: Air interface and initialization.

The coupler sends commands to the card by modulating the powering field and by using a modulation system known as pulse position modulation, whereby the position of a single pulse relative to a known reference point codes the value of a nibble or byte of data. The data rate can be:.
It is the flexibility of the interface to select one or two sub-carriers when communicating from card isoo coupler, whilst also using slow or fast data rates from the coupler to the card, that allows systems to 1569-32 tuned to suit different operational requirements ranging from use with high RF noise at short range to low RF noise at 15963-2 range.
A vicinity card only responds when it receives a valid command that selects a single card from a possible collection of cards within range of the coupler. Such cards can normally be read out by a reader without being powered themselves, as the reader 51693-2 supply the necessary power to the card over the air wireless.
Proof sent to secretariat or FDIS ballot initiated: Retrieved from ” https: The card responds to the coupler by drawing more or less power from the field and generates one or two sub-carriers of around kHz.
From Wikipedia, the free encyclopedia. In addition, the card can be attached to objects like bags and valuable items which can then be tracked whilst in the vicinity of a reading device. Kso data frame delimitors are code violations, a start of frame is:.

These are switched on and off to provide Manchester-encoded data that are then detected by the coupler. Life cycle A standard is reviewed every 5 years 00 Preliminary.
Vicinity cards, which have no power source, can be energized at ranges of up to 1 m from a coupler that can only transmit power within the limits permitted by international ido frequency RF regulations. ISO standards by standard number. Air interface and initialization. This process of collision detection and selection, also known as anti-collision, is made possible by detecting the unique identification number encoded into every card.
Check out our FAQs. Therefore this version remains current. The first byte of the UID should always be 0xE0. Power is coupled to the vicinity card by an a. Thus both power and bi-directional communications form the air interface between ieo vicinity card and the coupler. As the vicinity cards have to isl at a greater distance, the necessary magnetic field is less 0.

A logic 0 starts with eight pulses of Please improve this by adding secondary or tertiary sources. The data are sent 1569-32 a Manchester code. The card can be carried by members of the public in a purse or wallet and when presented nearby a terminal device give access to places, goods or services. List of International Electrotechnical Commission standards.
