What Is A QR Code?
A QR code is a type of barcode that can be read by smartphones and other devices. QR codes are used to store information such as website URLs, contact information, or election ballots.
QR codes can be created with a free online QR code generator like the one above. Once you have generated your QR code, you can print it out and use it like any other barcode. To read a QR code, simply open the camera app on your smartphone and hold it up to the code. The phone will automatically read the QR code and display the stored information .
