Abstract: A checkout system is provided for carrying out a two-factor authentication process where coded products are purchased and theft activity might be pursued. The system typically includes an identification code reader for reading product identification codes (e.g. UPC bar code symbols or EPC-encoded RFID tags) on products that are passed through the point of sale (POS) and a security code detector/reader for automatically detecting/reading a security code (e.g. implemented as an EAS tag or an RFID tag) at the POS. During product checkout operations, the identification code reader reads identification codes, and the security code detector/reader detects or reads security codes applied to products. Collected identification and security data is automatically processed using identification and security data stored in a database to determine whether or not each product being purchased at the POS is in compliance or not in compliance with a two-factor authentication process supported by the checkout system.

Abstract: An optical indicia reading terminal can comprise a microprocessor, a memory, an image sensor integrated circuit including a two-dimensional image sensor, and a hand held housing encapsulating the two-dimensional image sensor. The image sensor integrated circuit can be configured to output a plurality of digital signals, each digital signal being representative of light incident on at least one pixel of the two-dimensional image sensor. The optical indicia reading terminal can be configured to store in the memory a frame of monochrome image data by selectively acquiring a plurality of luminance signals from the plurality of digital signals. Each luminance signal of the plurality of luminance signals can be representative of luminance of light incident on at least one pixel of the two-dimensional image sensor. The optical indicia reading terminal can be configured to process the frame of image data for decoding decodable indicia.
