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

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

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

The present invention relates to various methods of collecting and using data from RFID tags associated with items of interest. In one embodiment, the permissible error tolerance associated with the location of an RFID-tagged item may be altered, either manually or automatically. In another embodiment, RFID-tagged items may be associated with certain categories of items, based either on default or user-specified categories.

RFID data collection and use

Various systems and methods of handling items such as files are disclosed, including systems and methods for polling RFID-tagged items while they are stored in storage areas.

Radio frequency identification in document management

The present invention implements, in a data processing environment, many of the attributes of paper Post-it&#xae; notes. The note program of the present invention need not be resident in an application program, and the notes of the present invention may be moved directly between windows or between regions without being saved in an intermediate memory, may be easily dispensed either from a note dispenser of a window or on a desktop, may overlap the boundary of a window, may be automatically saved, may be attached to a document within a window so that the note moves with the document, may overlap a boundary of a window, may be resized with the constraint that the note may not be resized off of a window, may be moved across a window boundary, and may be attached to an object, such as a character, a word, a sentence, or paragraph of a document.

Software notes

A user interface for a radio frequency identification interrogation system is disclosed, which interface may include graphics, sounds, lights, or combinations of the foregoing that provide information to a user in regard to the materials being interrogated.
