What is Online QR Code Generator?
QR Code Generator is a free online tool for generating QR codes. QR Code stands for “Quick Response Code”. QR Code is a 2-Dimensional barcode first used in 1994, originating from the Japanese automotive industry. Its popularity among other barcode types comes from its high capacity for storing data.
Although there are many usage areas of QR Codes, they are mostly used for directing users to websites and mobile applications on Google Play and Apple Store. Other than that, you can use them to create vCards, send e-mails, make or receive payments, share WiFi credentials, and much more.
How do QR Codes Work?
QR Codes are formed from a white background and black squares (called modules). The longer the text, the higher the number of squares. Here is a sample QR Code:
Every QR Code contains three large square “finder patterns” in three corners. These help scanners quickly detect and orient the code. The remaining area contains the encoded data along with error correction information, which allows the code to be read even if up to 30% of it is damaged or obscured.
