Abstract
An access system includes a portable pouch and an access unit. The pouch has an inserted electronic card, a card receive module and a send/receive module. The access unit is assigned to a transit region of the zone and has a send/receive unit for a communication with the send/receive module of the pouch. To provide access, the tag is transmitted to the send/receive unit of the access unit when the pouch is within range of the send/receive unit. If the tag received by the send/receive unit matches a stored tag, an unblocking signal for providing access to the zone is generated. A signal detector of the pouch detects an electromagnetic field generated by a send unit arranged in the transit region, and information transmitted by the electromagnetic field is processed. A bidirectional communication between the send/receive unit of the access unit and the send/receive module of the pouch is initiated.

23. In a system for providing access to a predetermined zone and including a portable pouch having an inserted electronic card, a card receive module and a send/receive module coupled to the card receive module, wherein the electronic card includes at least one tag, and wherein the tag is transmitted in a wireless manner from the card to the card receive module, and an access unit assigned to a transit region of the zone and having a send/receive unit configured for a communication with the send/receive module of the pouch, a method for providing access to the predetermined zone, comprising:
-
transmitting the tag to the send/receive unit of the access unit when the pouch is within a predetermined range of the first send/receive unit; determining by the access unit if the tag received by the send/receive unit matches a stored tag; generating an unblocking signal for providing access to the zone if the received tag and the stored tag match; detecting with a signal detector of the pouch an electromagnetic field generated by a send unit arranged in the transit region; processing information transmitted by means of the electromagnetic field, wherein the information defines a predetermined minimum receive level necessary for activating electronic components of the pouch; and initiating a bidirectional communication between the send/receive unit of the access unit and the send/receive module of the pouch. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31)

42. An access unit for providing access to a zone with an electronic card containing at least one personified tag, comprising:
-
a send/receive unit for communication with an electronic pouch containing a card in order that a personified tag is transmitted from the pouch to the send/receive unit; a card reader; and a card load modulation unit connected to the send/receive unit, wherein the tag is transmitted by means of a card emulation.
