Zint compilation on the Win32 platform, and zint
Zint is an open-source Code library that supports over 50 types of Code, including Code-128, Data Matrix, EAN-128, UPC/EAN, ITF, QR Code, Code 16 k, ipv417, microipv417, LOGMARS, Maxicode, GS1 DataBar, Aztec, Composite Symbols, etc. Basically, you can use the bar code you have seen to encode it, it supports direct output of PNG format image files and bitmap byte arrays.

If it can use Google's own technology to direct the entire industry, as long as the company that is working on bar code projects in the future uses mobile phone bar code technology to buy its patents, it will have a monopoly.

must have an exclusive IP Address
As IPv4 is about to be allocated, many people are concerned about this issue. Each IP Address can only install one SSL certificate. However, if you use a wildcard SSL Certificate (wildcard SSL Certificate, the price is about $125 per year), you can deploy multiple HTTPS subdomains on one IP address. For example, https://www.httpwatch.com and https://store.httpwatch.com share the same IP address.
