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.

Methods and systems for enhancing read accuracy in an automated license plate reader system

The present invention relates to RFID devices, including handheld RFID devices, and applications for such devices. The devices and applications may be used in connection with items that are associated with an RFID tag, and optionally a magnetic security element. The devices and applications are described with particular reference to library materials such as books, periodicals, and magnetic and optical media.

Applications for radio frequency identification systems

The invention relates to the use of RFID systems for use with items of interest having RFID tags, such as in a library. The invention has particular applicability to determining the location, order, and other information regarding such items.

Radio frequency identification systems applications

A library terminal permits a user to execute a loan transaction without assistance. The library terminal (i) provides a visible scan line from a bar code reader indicating the correct positioning of the bar code on a circulating item, (ii) leads a user through a loan transaction, (iii) provides an explicit feedback to a user when an article has an improper position on the article receiving area, (iv) both checks out and checks in circulating items, (v) stores fonts in bit maps of screen displays instead of in a separate font memory, (vi) integrates a security marker reader, a printer, and a controller in the same housing, (vii) processes financial transactions related to the borrowing of circulating items, and/or (viii) displays actions for helping the user to correct errors in use of the terminal.

System for processing financial transactions in a self-service library terminal

Methods and systems for collecting, tagging, searching for, retrieving, inventorying, and transferring evidence by law enforcement officials are described, in which RFID tags associated with pieces of evidence can be interrogated to assist in locating information relating to that evidence.

Evidence and property tracking for law enforcement

Terminal for libraries and the like

A combination tag is disclosed, including a magnetically-responsive element and a radio frequency-responsive element. In one embodiment, the magnetically-responsive element also functions as an antenna for the radio frequency-responsive element.

Identification tag with enhanced security

A library terminal permits a user to execute a loan transaction without assistance. The library terminal (i) provides a visible scan line from a bar code reader indicating the correct positioning of the bar code on a circulating item, (ii) leads a user through a loan transaction, (iii) provides an explicit feedback to a user when an article has an improper position on the article receiving area, (iv) both checks out and checks in circulating items, (v) stores fonts in bit maps of screen displays instead of in a separate font memory, (vi) integrates a security marker reader, a printer, and a controller in the same housing, (vii) processes financial transaction related to the borrowing of circulating items, and/or (viii) displays actions for helping the user to correct errors in use of the terminal.
