almost every cell phone has a built in QR code scanner

QR codes, which stands for Quick Response Code, is a two-dimensional barcode that is commonly used in mobile phones. QR codes are used to store information and can link to websites or other mobile applications. People have been using QR codes since the early 2000s, but the concept behind them has evolved.

For example, some companies have created QR codes to be scanned to send emails or text messages. QR codes were first used by Toyota, which wanted to promote its new Lexus model. By placing the QR code onto a model car, Toyota hoped that people would scan the code and receive information about the Lexus.

A similar strategy was used by Walmart to promote qr code reader in their new store in Japan. Wal-Mart placed a QR code on a package to help people find the new store.

Nowadays, almost every cell phone has a built-in QR code scanner. People use it to share and download images, music, videos, games and many other types of information. Some people even use QR codes to transfer money.

QR code was originally developed by a company called Denso Wave, Inc. Today, they’re used by companies such as Apple, Google, Nike and others. The most popular use of QR codes is for marketing purposes.
