A portable communication terminal requests merchandise information from a store management apparatus, by using store identity information about a store where a purchasing transaction is made, and merchandise information about merchandise to be purchased. The store management apparatus has a merchandise information storage configured to store merchandise information including a price of merchandise to be sold in each store. The store management apparatus receives a merchandise information request from a portable communication terminal, retrieves a merchandise information storage, detects merchandise information matching a retrieval condition, and sends the merchandise information to the request source, i.e., the portable communication terminal. The portable communication terminal displays merchandise information sent from the store management apparatus in a display.

An electronic watermark generating apparatus color-converts an RGB image, and divides the color-converted image into a plurality of blocks. Then, the apparatus embeds to-be-embedded information as an electronic watermark into blocks in which an irreversible compression image has been quantized, the image being produced by carrying out quantization on a block-by-block basis, and restores the RGB image by carrying out de-quantization with respect to the blocks. The above apparatus color-converts the restored RGB image, and divides the color-converted image into a plurality of blocks. Thereafter, the apparatus carries out quantization on a block-by-block basis, and extracts to-be-embedded information from the thus quantized blocks. The apparatus embeds the to-be-embedded information as an electronic watermark again in the quantized blocks when it is not checked that the to-be-embedded information has been correctly extracted.

Tag information which has been previously read but is not currently read is retrieved every time tag information is collectively read by a wireless tag reading device. When corresponding tag information is detected, sales information of a commodity is acquired from this tag information, and the acquired sales information is registered in a sales registering section. Further, display contents in a display device are changed in response to detection of the tag information which has been previously read but is not currently read. Furthermore, when information concerning a commodity for sale is input through a barcode reader, sales information of the commodity is acquired from this input information, and the acquired sales information is registered.

Commodity sales registration processing system and commodity information registering apparatus

There is disclosed a commodity information registering apparatus which registers commodity information while a commodity is moved, comprising a radio tag reading section which reads a radio tag within a first field to acquire commodity identification information stored in the radio tag, an optical reading section which reads a code symbol within a second field to acquire commodity identification information described in the code symbol, and a registering section which registers one of the commodity information corresponding to the commodity identification information acquired from the radio tag and the commodity information corresponding to the commodity identification information acquired from the code symbol.
