A POS terminal (code reading device) according to one example embodiment of the present invention includes: a code reading unit that reads information of a code based on a reflected light from the code attached to an item; and a discount processing unit that makes a discount of the item when the information of the code is not read by using a first light being irradiated on the code and the information of the code is read by using a second light being irradiated on the code, wherein the second light is different from the first light.

An entertainment system includes a user interactive device having an identification assembly configured to generate a pattern of light via reflective material, a camera configured to capture the pattern of light generated by the reflective material, and a controller having processing circuitry and a memory. The memory stores machine-readable instructions configured to cause the processing circuitry to receive an indication of the pattern of light and determine identification data associated with the user interactive device based on the pattern of light.

Techniques to improve detection and security of images, including formation and detection of matrix-based images. Some techniques include logic to process image data, generate one or more colorspaces associated with that data, and perform colorspace conversions based on the generated colorspace. The logic may be further configured to generate an image based on the colorspace conversions, including but not limited to a matrix bar code. The logic may be further configured to apply an infrared layer to the image, e.g. matrix barcode, generated from the colorspace conversion(s).

The logic may be further configured to generate an image based on the colorspace conversions, including but not limited to a matrix bar code. The logic may be further configured to apply one or both of an ultraviolet layer and an infrared layer to the image, e.g. matrix barcode, generated from the colorspace conversion(s). Other embodiments are described and claimed.

Techniques to improve detection and security of images, including formation and detection of matrix-based images. A histogram may be used to determine a most prevalent plurality of colors associated with an environment. A related plurality of colors may be determined based on the most prevalent plurality of colors. A matrix barcode may be generated based on the related plurality of colors and an infrared layer.

An article of manufacture may include a matrix barcode on a physical medium and associated with an environment. The matrix barcode may include a plurality of colors, where at least one of the plurality of colors is a least prevalent color, of a plurality of prevalent colors in the environment.

A novel optically readable identification code and a toy with identification code with which a toy main body can be prevented from having the appearance compromised as much as possible are provided. A toy with identification code 10 includes a toy main body 11 with a surface provided with an identification code portion 12 including an optically readable identification code 13. The identification code 13 includes a plurality of dark color portions and a plurality of light color portions, and a chromatic color having an intensity lower than an intensity of a chromatic color used for the dark color portions is used for the light color portions.

A computer-implemented system includes a printing apparatus and a processor. The printing apparatus is configured for printing a ballot and an envelope associated with the ballot and a voter. The processor is configured to access a request file defining voter data from a voter registration database and generate a set of print instructions including ballot print instructions for a ballot and envelope print instructions for an envelope. Both of the ballot print instructions and the envelope print instructions are generated using the request file, and the set of print instructions includes instructions for printing a first machine-readable identifier for the envelope. The processor is further configured to transmit an instruction to the printing apparatus to print the ballot and the envelope using at least a portion of the voter data defined by the request file, the envelope including the first machine-readable identifier corresponding to the voter.

A computer-implemented system for printing ballots, ballot envelopes, and associated elections documents is disclosed.
