How do I use the Barcode/QR Code Mode?

Last updated 10 months ago

Please register a code on some household object, such as a toothpaste, or a book. Any barcode can be registered. Place these objects as far away from bed as possible for maximum effect. Also, you can generate and print a QR code to stick to any object or place you want. You can generate QR codes here, on (https://www.the-qrcode-generator.com/).
