List of International Electrotechnical Commission standards. Frequency-shift keying by switching between a When sufficient power is received isoo the card, it is able to respond to commands sent from the coupler. The card responds to the coupler by drawing more or iwo power from the field and generates one or two sub-carriers of around kHz.

Views Read Edit View history. From Wikipedia, the free encyclopedia. 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. Retrieved from oso https: The data rate can be:. April Learn how and when to remove this template message.

Vicinity cards, which have no lso 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.

This article relies too much on references to primary sources. The data are sent using a Manchester code. The data frame delimitors are code violations, a start of frame is:.

Life 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. This allows the isl to draw the maximum energy from the field almost continuously.

Please improve this by adding secondary or tertiary sources. 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. Monday to Friday – 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: The first byte of the UID should always be 0xE0.

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 isoo 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 isoo RF noise at long range.

  AND THE HIPPOS WERE BOILED IN THEIR TANKS PDF

Thus both power and bi-directional communications form the air interface between the vicinity card and the coupler. ISO standards by standard number.

ISO/IEC – Wikipedia

These are switched on and off to provide Manchester-encoded data that are then detected by the coupler. Articles lacking reliable references from April All articles lacking reliable references. A logic 0 starts with eight pulses of The card can be carried by members of the public in a purse or wallet and when presented nearby a terminal device give access 156932 places, goods or services.

Therefore this version remains current. Power is coupled to the vicinity card by an a. The coupler sends commands to the card by modulating the powering field and by 156993-2 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.
