Optical Character Recognition
A type of computer software designed to translate images of handwritten or typewritten text (usually captured by a scanner) into machine-editable text, or to translate pictures of characters into a standard encoding scheme (such as ASCII or Unicode). OCR began as a field of research in pattern recognition, artificial intelligence and machine vision.
Order Management System
A software system used in a number of industries for order entry and processing. Such industries include e-commerce, cataloging and financial securities.
The position of a tag antenna vis-à-vis a reader antenna. With UHF systems, readers can be either circular-polarized or linear-polarized. When using a linear polarized antenna, the tag reader and antenna reader must be in alignment in order to achieve the longest reading distance. If that tag antenna is aligned vertically and the reader is sending out signals horizontally, only a small portion of the energy emitted by the reader will hit the tag antenna.
Original equipment manufacturer
A company that builds its own products from components bought from other manufacturers.
