QR codes, or Quick Response codes, are two-dimensional barcodes that can be scanned by a smartphone or other mobile device equipped with a QR code reader. You’ve probably seen them in printed material and also on videos. Here’s what they look like. I created this one to make it easy for people to go online and purchase my books.
They were first invented in the 1990s by a Japanese company named Denso Wave. QR codes can be used for a variety of purposes, such as providing quick access to a website, sharing contact information, or displaying product information. They are commonly used in marketing and advertising, but can also be used for personal purposes like sharing your phone number or email address.
QR codes can be found on a variety of surfaces, such as billboards, magazines, product packaging, and business cards. They are a fast and convenient way to access information and can be a valuable tool for businesses and individuals alike.
To use a QR code, you will need a smartphone or other mobile device equipped with a QR code reader app. These days most smartphone cameras have that capability built in, but there are many free QR code reader apps available for download from the app store.
To use the QR code simply open your camera and point it at the QR code. The app will automatically scan the code and display its contents. This could be a link to a website, a phone number, or any other type of information. To use a link, simply tap it when it displays.
On my camera, I can tap Show Options and choose to open the link or copy it to my clipboard to paste into a note for later use.
