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 data are sent using a Manchester code.
Monday to Friday – Air interface and initialization. As the vicinity cards have to operate at a greater distance, the necessary magnetic field is less 0. This page was last edited on 22 Novemberat 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 allows the card to draw 115693-2 maximum energy from the field almost continuously.

ISO standards by standard number. 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.
The data frame jso are code violations, a start of frame is:. Proof sent to secretariat or FDIS ballot initiated: April Learn how and when to remove this template message. The data rate can be:. This article relies too much on references to primary sources.
Thus both power and bi-directional communications form the air interface between the vicinity card and the coupler. The coupler sends commands to the card by modulating the powering isso 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.
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. 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 radio frequency RF regulations. Views Read Edit View history.
Ieo Wikipedia, the free encyclopedia. These are switched on and off to provide Manchester-encoded data that are io detected by the coupler.
Please improve this by adding secondary or tertiary sources. Life cycle A standard is reviewed every 5 years 00 Preliminary. 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.
115693-2 Frequency-shift keying by switching between a It is the 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.
The card responds to the coupler by drawing 15693- or less power from the field and generates one or two sub-carriers of around kHz. Check out our FAQs. Retrieved from ” https: 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.
