According to one embodiment, a reading apparatus is arranged between an operator and a customer face-to-face standing. The reading apparatus includes a main body, a first image capturing section for the operator, a second image capturing section for the customer, and a processing section, an output section. The first image capturing section is arranged at the main body and photographs a commodity. The second image capturing section is arranged at the main body and photographs the customer-holding object. The processing section executes sales registration. The output section acquires images captured by the first and second image capturing sections to output the images to the processing section. When transaction starting is instructed, the output section acquires the images captured by the first and second image capturing sections and adds an identifier to each image to be output to the processing section. The identifier represents a source capturing an image.
