AUTOMATIC INTEGRATED SENSING AND ACCESS CONTROL
First Claim
Patent Images
1. A transit system for sensing exposure to an item of interest, the transit system comprising:
- a unique identifier of a media;
an exposure detector that detects exposure of the media to the item of interest, wherein the exposure detector determines whether the media has been exposed to the item of interest based, at least in part, on a detected optical change in a detection material of the media;
a processor coupled to the exposure detector, wherein;
the unique identifier is flagged when the exposure to item of interest is detected, anda message is communicated away from the processor to a remote location when the unique identifier is flagged; and
an access control point that;
automatically reads the unique identifier of the media, anddenies access beyond the access control point based, at least in part, on a determination that the unique identifier is flagged.

Abstract
An access control system for sensing exposure to items of interest for a person associated with a unique identifier of a fare card or ticket is disclosed. The access control system includes the unique identifier, an exposure detector and a processor. The unique identifier associated with the person that is flagged when exposure is detected. The exposure detector detects exposure to items of interest by the person. The processor is coupled to the exposure detector. The message is communicated away from the processor to a remote location when the unique identifier is flagged.

8. A system for sensing exposure to items of interest for a person associated with an identifier that is machine-readable from access control media, the system comprising:
-
the identifier of the access control media associated with the person, the identifier being machine readable from the access control media; an exposure detector that detects whether the access control media has been exposed to one or more items of interest based, at least in part, on a detected optical change in a detection material of the media; a processor coupled to the exposure detector, wherein; the identifier is flagged when the exposure to one or more items of interest is detected, an exposure condition being stored by the access control media, and a message is communicated away from the processor to a remote location when the identifier is flagged; and an access control point that reads the identifier of the access control media, wherein the unique identifier is used, at least in part, to determine whether to allow access beyond the access control point. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method for flagging a media used in an access control system based, at least in part, upon exposure to at least one predetermined item of interest, the method comprising:
-
providing a machine-readable identifier associated with the media; determining if the media was exposed to the at least one predetermined item of interest based, at least in part, on a detected optical change in a detection material of the media; flagging the machine-readable identifier when the determining results in a determination that there was exposure to the at least one predetermined item of interest; notifying a point away from a location where the machine-readable identifier was provided that the machine-readable identifier is flagged; automatically reading information from the media; and controlling access of a person based, at least in part, on whether the machine-readable identifier is flagged. - View Dependent Claims (16, 17, 18, 19, 20, 21)
