A QR code, short for Quick Response code, is a type of two-dimensional barcode that can be scanned by smartphones and other devices. QR codes are often used to store website URLs, contact information, or other data. To make a QR code for a link, you can use a free online QR code generator. These generators allow you to enter the URL or other data you want to encode, and then generate a QR code that you can download and share.
QR codes are becoming increasingly popular as a way to share information quickly and easily. They are often used on business cards, posters, and other marketing materials. QR codes can also be used to track website traffic, or to provide customers with additional information about a product or service.
