Smart card detectors
First Claim
1. A detector card for recording exposure to an item of interest, the detector comprising:
- a media;
an antenna for sending exposure information, wherein the antenna is embedded in the detector card;
a power source that inductively couples energy into the detector card;
an electronic circuit embedded in the media, wherein the electronic circuit is wirelessly readable; and
a material that reacts when exposed to the item of interest, wherein the electronic circuit can detect if the material has reacted.

Abstract
A smartcard or other media detects the presence of chemical, biological, radiation, and/or explosive (CBRE) compounds or other items of interest on individuals handling the smartcard or other media. The exposure is stored such that, when the card is presented to a reader, the detection data is transmitted to the reader for appropriate processing by the system. In one embodiment, this invention provides a detection methodology which captures the fact that the holder of the detection device has been in contact with an item of interest without external power. The detector card is then able to alert appropriate authorities of that exposure when the device is presented to a reader in the normal course of the holder'"'"'s business.
