QR 코드 – Denso-Wave Corporation(일본)에서 10년 이상 전에 도입한 매트릭스 코드로, 처음에는 자동차 산업에서만 사용되었지만 다른 산업에서 그 유용성이 빠르게 인정되었습니다. 바코드는 물체에 대한 정보가 포함된 광학 레이블에 불과하며 읽기는 특수 장치(이 경우 모바일 장치의 카메라)로 수행됩니다. 빠른 응답 코드는 흰색 배경에 작은 검은색 사각형이 무작위로 배열된 것처럼 보입니다.
이 2차원 바코드는 제품 패키지의 쇼핑 센터, 인쇄된 출판물의 페이지 및 인터넷 리소스와 같은 현대 생활의 모든 곳에서 볼 수 있습니다. QR코드로 암호화된 정보를 이용하면 특정 리소스에 빠르게 접근할 수 있는데, 그 링크가 코드에 쓰여져 있고, 이메일이나 문자 메시지를 읽고, 좌표를 찾는 등의 작업을 할 수 있다. 대부분의 최신 스마트폰 및 태블릿에는 기본적으로 바코드를 읽는 프로그램이 시스템에 있습니다. 그러나 이러한 유틸리티의 편리함과 기능이 모든 사용자에게 적합한 것은 아닙니다.
이러한 경우 대체 소프트웨어가 구출되므로 유틸리티 QR & 바코드 스캐너를 사용하면 Wi-Fi 네트워크에 자동으로 연결하고, URL로 이동하고, 책 에디션의 고유 번호( 국제 표준 도서 번호) 를 선택하고 선택한 제품에 대한 전체 정보를 볼 수 있습니다. 프로그램에는 플래시 켜기, 자동 초점, 바코드 반전, 전체 스캔 기록 보기와 같은 유용한 기능이 있습니다.
