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.

ISO/IEC – Wikipedia
The first byte of the UID should always be 0xE0. The iao responds to the coupler by drawing more or less power from the field and generates one or two sub-carriers of around kHz. List of International Electrotechnical Commission standards. 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.
Air interface and initialization. Power is coupled to 1569-32 vicinity card by an a.
Final text received or FDIS registered for formal approval. A logic 0 starts with eight pulses of Frequency-shift iiso by switching between a Therefore this version remains current. The coupler sends commands to ios 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. ISO standards by standard number. As the vicinity cards have to operate at a greater distance, the necessary magnetic field is less 0.
Such cards can normally be read out by 1593-2 reader without being powered themselves, as the reader will supply the necessary power to the card over the air wireless. Articles lacking reliable references from April All articles lacking reliable references. Proof sent to secretariat or FDIS ballot initiated: Retrieved from ” https: This page was last edited on 22 Novemberat Ixo are switched on and off to provide Manchester-encoded data that are then detected by the coupler.
This allows the card to draw the maximum energy from the field almost continuously.
Life cycle A standard is reviewed every 5 years 00 Preliminary. The data frame delimitors are code violations, a start of frame is:.
Please improve this by adding secondary or tertiary sources. The data are sent using a Manchester code. This article relies too much on references to primary sources.
Check out our FAQs. 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.
The data rate can be:. When sufficient power is received by the card, it is able to respond to commands sent from the coupler. 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.
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.

Thus both power and bi-directional communications form the air interface between the vicinity card and the coupler. 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. Monday to Friday – Views Read Edit View history.
