Radio frequency identification device with visual indicator
First Claim
1. A label attached to a container or product shipped by air, said label comprising radio-frequency identification (RFID) device, said RFID device comprising:
- a chip;
an antenna operatively coupled to the chip; and
a display operatively coupled to the chip;
wherein the antenna is configured to receive signals to be passed on to the chip;
wherein the operability of the RFID device is disabled during aircraft flight by sending a first signal to the RFID device causing the RFID device to temporarily suspend normal operations; and
wherein the display comprises a visual indicator that provides a visual indication of an operative state of the RFID device, and the visual indicator selectively displays or obscures underlying printed material.

Abstract
An RFID device includes a chip, an antenna operatively coupled to the chip, and a visual indicator operatively coupled to the chip. The visual indicator provides a visual indication of an operative state of the device. The visual indication may be human readable and/or machine readable, and may provide visual indication that is dependent on a change in an operative state of the device. The operative state that triggers the visual indication may include a state in which the chip has temporarily or permanently been rendered inoperative or disabled, that is, in which the chip no longer responds to, or otherwise interacts with, ordinary incoming RF signals such as from a device reader. The visual indicator may be included in a display that functions by any of a variety of suitable mechanisms, such as by use of electrochromic materials, thermochromic materials, liquid crystals, or chemically-reactive materials.
