1. A license plate, comprising:
- a license plate blank to which is attached a reflective sheeting; and
a machine readable element including useful information accessible through a first channel and checking information only to verify the accuracy of the transmission of the useful information transmitted via the first channel without duplicating or replicating useful information accessible through a second channel, wherein the second channel is devoted solely to the transmission of checking information, and wherein the first channel and the second channel are separated by at least one of;
wavelength, time, position, or medium.

Abstract
One embodiment of the apparatuses, methods, and systems of the present disclosure is a license plate, sticker, or ALPR system having enhanced or increased accuracy. At least one of the license plate, sticker, or ALPR system includes useful information that is transmitted over a first channel and checking information that is transmitted over a second channel. The second channel is devoted solely to transmitting the checking information (e.g., the second channel does not transmit useful information). In other words, the license plates, stickers, and ALPR systems of the present disclosure include at least one channel that is devoted solely to transmitting checking information.

12. A method of enhancing the accuracy of license plate readings, comprising:
-
providing a license plate including useful information; providing checking information only to verify the accuracy of the transmission of the useful information transmitted via the first channel without duplicating or replicating useful information; reading the useful information through a first channel; and reading the checking information through a second channel that differs from the first channel and using the checking information to verify the accuracy of the reading of the useful information, wherein the first channel and the second channel are separated by at least one of;
wavelength, time, position, or medium.
