Abstract
A wrapping material includes a sheet of non-rigid material; a first substantially planar RFID that is attached to the sheet of non-rigid material, the first RFID having a main body and a closed-loop conductor extending from the main body of the first RFID; and a second substantially planar RFID is attached to the sheet, the second RFID having a main body and a closed-loop conductor extending from the main body of the second RFID; and wherein the closed-loop conductor of the first RFID is arranged relative to the closed-loop conductor of the second RFID such that all straight lines that lie between the first RFID and the second RFID and that do not intersect the main body of the first RFID or the second RFID intersect the closed-loop conductor of the first RFID and/or the second RFID.

14. A wrapping material, comprising
a. a sheet of non-rigid material; -
b. a first substantially planar RFID device that is attached to the sheet of non-rigid material, the first RFID device having a main body and a closed-loop conductor extending from the main body of the first RFID device; and c. a second substantially planar RFID device that is attached to the sheet of non-rigid material, the second RFID device having a main body and a closed-loop conductor extending from the main body of the second RFID device; and wherein the closed-loop conductor of the first RFID device is arranged relative to the closed-loop conductor of the second RFID device such that all straight lines that lie between the first RFID device and the second RFID device and that do not intersect the main body of the first RFID device or the second RFID device intersect the closed-loop conductor of at least one of the first RFID device and the second RFID device.

- 15. The wrapping material of claim 0, wherein the sheet of non-rigid material has a substantially rectangular shape and wherein the first substantially planar RFID device and the second substantially planar RFID device are arranged longitudinally along the length of the sheet of non-rigid material.
-
18. The wrapping material of claim 0, further comprising a third substantially planar RFID device that is attached to the sheet of non-rigid material, the third RFID device having a main body and a closed-loop conductor extending from the main body of the third RFID device;
- and wherein the closed-loop conductor of the second RFID device is arranged relative to the closed-loop conductor of the third RFID device such that all straight lines between the second RFID device and third RFID device not intersecting the main body of the second RFID device or the third RFID device intersect the closed-loop conductor of at least one of the second RFID device and the third RFID device.
-
19. A system for tracking whether a container has been opened, comprising a first RFID device configured to be attached to a container and to be disabled when an opening into the container is made or expanded.
The system of claim 19 for tracking whether a container has been opened, further comprising a second RFID device configured to be attached to a container.
-
20. The system of claim 0 for tracking whether a container has been opened, further comprising a detector configured to monitor whether identification information is received from the first RFID device;
- and wherein the first RFID device has a receiver configured to receive energy from wireless signals.
