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. As the vicinity cards have to operate at a greater distance, the necessary magnetic field is less 0. The data rate can be:. A logic 0 starts with eight pulses of The data frame delimiters are code violations, a start of frame is:. The data are sent using a Manchester code.

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. 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. Power is coupled to the vicinity card by an a. When sufficient power is received by the card, it is able to respond to commands sent from the coupler. 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. This allows the card to draw the maximum energy from the field almost continuously.
