QR-Codes have become more popular than the typical barcode as the typical barcode can only hold a maximum of 20 digits, whereas the QR-Code can hold up to 7,089 characters. This makes the use and diversity of QR-Codes much more appealing than their older counter part, the barcode.
Partially part of the reason QR-Codes can hold more data, is because if you compare a typical barcode to a QR-Code, you can see one major difference; barcodes only span horizontal whereas QR-Codes can span horizontally and vertically.
What is a QR Code?
A QR Code (it stands for "Quick Response") is a 2-dimentional bar code that's been used in Japan since 1994 and is widely used in Europe. QR Codes are quickly gaining popularity in the United States.
QR Codes can be decoded by most camera equipped mobile phones. They can be effectively embedded in magazines, in-store graphics, signage, business cards or any application where additional information is required. By scanning the code, a user is directed to any website, personal URL, phone number, SMS text messaging, or text description without having to type or search for the correct link. You might even be presented with a special coupon offer.
