With the emergence of smart phones and tablet computers, the digital age has also slowly hit the smart pace. Faced with the massive digitalization, the status of the traditional era was greatly shaken. In this series of processes, such a new technology was born. Such a small product has brought about such a big change in our daily life. It is a QR code.

QR code "QR" is an abbreviation for Quick Response. This QR code can be quickly read. Compared with previous bar code, QR code can store richer information, including encrypting text, URL address and other types of data. .

It is a wise choice to keep the QR code size at 3/4" x 3/4" if possible. Although the camera on the phone will get better and better, so more people can scan those very small QR codes, but you have to admit that there are still many people scanning 1 / 2 "x 1 / 2" size QR There will be trouble when you code.

2. Make sure there is plenty of blank space near your QR code.
