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.

Final text received or FDIS registered for formal approval. April Learn how and when to remove this template message. 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.

Please improve this by adding secondary or tertiary sources. The data frame delimitors are code violations, a start of frame is:. This page was last edited on 22 Novemberat From Wikipedia, the free encyclopedia.
Articles lacking reliable references from 15963-2 All articles lacking reliable references. This allows the card to draw the maximum energy from the field almost continuously.
The data rate can be:. The first byte of the UID should always be 0xE0. The data are sent using a Manchester code.
A logic 0 starts with eight pulses of Therefore this version remains current. When sufficient power is received by the card, it is able to respond to commands sent from the coupler. List of International Electrotechnical Commission standards. These are switched on and off to provide Manchester-encoded data that are then detected by the coupler.
Check out our FAQs. It is 15693-22 flexibility of the interface to select one or two sub-carriers when communicating from card to coupler, whilst also using slow or fast data rates from the coupler to the card, that allows systems to be tuned to suit different operational requirements ranging from use with high RF noise at short range to low RF noise at long range. Air interface and initialization. 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.
This article relies too much on references to primary sources. Vicinity cards, which have no power source, can 1693-2 energized at ranges of up to 1 m from a coupler that can only transmit power within the limits permitted by international radio frequency RF regulations. Views Read Edit View history. As the vicinity cards have to operate at a greater distance, the necessary magnetic field is less 0.
Proof sent to secretariat or FDIS ballot initiated: Monday to Friday – 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. 1569-32 cycle A standard is reviewed every 5 years 00 Preliminary. Such cards can normally be read out by a reader without being powered themselves, as the reader will supply the necessary power to the card over the air wireless.
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.
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. Power is coupled to the vicinity card by an a.
