QR code, also known as QR code, is short for quick response. It is a very popular encoding method on mobile devices in recent years. It can store more information than traditional bar code codes, it can also represent more data types, such as characters, numbers, Japanese, a

Following the previous introduction of a Japanese Open-Source Software (this software can only implement QRCode) Original article: Java implements code and decoding of the QR code QRCode. Now we find another excellent open-source tool-ZXing, it is more flexible and convenient, and supports multiple encoding formats. Full text directory: Basic Introduction Demons

Now two-dimensional code is some of our software station or download station commonly used a thing, in particular, will use two-dimensional code to add friends, below I will introduce the use of PHP to generate a number of two-dimensional code methods. Method One this generation is a two-dimensional code in the middle

I tried the QR code scanning software on my Android mobile phone over the weekend and scanned my train tickets, business cards, and so on. It was very nice and interesting. Of course, Java can also implement this. Now I will share how to simply use Java to implement the encoding and decoding of QRCode In the QR code (w
