ISO/IEC – Wikipedia

As the vicinity cards have to operate at a greater distance, the necessary magnetic field is less 0. Life cycle A standard is reviewed every 5 years 00 Preliminary. 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 lso 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 – Frequency-shift keying by switching between a This allows the card to draw the maximum energy from the iiso almost continuously. This page was last edited on 22 Novemberat List of International Electrotechnical Commission standards.

ISO standards by standard number. Power is coupled to the vicinity card by an a. 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.

Check out our FAQs. The data are sent using a Manchester code.

Air interface and initialization. When sufficient power is received by the card, it is able to respond to commands sent from the coupler.

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. By using this site, you agree to the Terms of Use and Privacy Policy.

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 responds to the coupler by drawing more or less power from the field and generates one or two sub-carriers of 1593-2 kHz.

The data rate can be:. It is the flexibility of the interface to select one or two sub-carriers 1593-2 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.

Therefore this version remains current. Final text received or FDIS registered for formal approval. The data frame delimitors are code violations, a start of frame is:. Vicinity cards, which have no power source, can be energized at ranges of up to 1 m from a coupler lso can only transmit power within the limits permitted by international radio frequency RF regulations.

These are switched on and off to provide Manchester-encoded data that are then detected by the coupler.

Retrieved from ” https: April Learn how and when to remove this template message. This process 156932 collision detection and selection, also known as anti-collision, is made possible by detecting the unique identification number encoded into every card. From Wikipedia, the free encyclopedia. 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.
