Here, the QR code (Quick Response Code) is a two-dimensional (matrix) format code that contains various information in a square horizontal and vertical grid pattern, and the existing one-dimensional barcode can only store numerical information of about 20 characters. On the other hand, QR codes can store up to 7,089 numbers, up to 4,296 characters (ASCII), up to 2,953 binary (8-bit) bytes, and up to 1,817 Chinese characters, and have superior recognition speed, recognition rate, and resilience than regular barcodes. While barcodes are mainly used for calculations, inventory management, and product confirmation, QR codes are often used as a marketing, promotional, and PR tool. Additionally, only product sellers can own dedicated terminals that can read existing barcodes, so consumers can use barcodes. It was impossible to obtain information using QR codes, but in the case of QR codes, consumers can directly obtain product information as long as they have a smartphone.

The use of QR codes has increased with the spread of smartphones. Smartphone users can easily obtain various information by downloading the free QR code scanning application and then scanning the QR code posted on billboards, promotional materials, posters, magazines, the Internet, etc. with their smartphone. In the present invention, by using the QR code pre-printed in different ranges for each type of volume-rate garbage bags, including reusable volume-rate garbage bags and food volume-rate garbage bags, and scanning them with the QR code scanner 800, the garbage bag to be thrown away is It is used to check whether it is a reusable volume-rate garbage bag or a volume-rate food garbage bag.

The Arduino (300) linked to the QR code scanner (800) senses the infrared sensor (400) and places it in the trash can through the QR code scanner (800) when it is close for a certain period of time according to the timer program (601). When the QR code of the designated reusable waste or food waste volume-rate bag is recognized and when a user already registered in the application 1100 of the smartphone 1000 is nearby, the opening/closing cover 200 is opened when both are satisfied. It is programmed to control the operation of the opening and closing motor 210 and the intermittent motor 310.
