QR Codes in Delphi: Generating and Scanning

Two recent blog posts about QR codes and Delphi.

Just a short post referring to a couple of recent Delphi blogs on related topics:

TMS has a blog post about scanning QR code in a Delphi mobile application at www.tmssoftware.com/site/blog.asp?post=280. The code is based on an open source Objective-C library (zbar.sourceforge.net/) TMS wrote a wrapper Delphi component for. So this is iOS specific, but certainly a very nice demo!
Zarko has a blog post about producing QR codes with an open source library at zarko-gajic.iz.hr/generating-qr-codes-using-delphi-delphizxingqrcode-open-source-unit-by-debenu/. Would be interesting to see if the code could be easily ported to FireMonkey and mobile versions of Delphi.

QR Codes in Delphi Generating and Scanning

Google actually provide a QR code generator; 
https://google-
developers.appspot.com/chart/infographics/docs/qr_codes

There's no need for a third-party library for generation 
when this is available. Of course it does require an 
internet connection, but that's more likely than 
tracking down a QR library that works with FMX from the 
get-go.

QR Codes in Delphi Generating and Scanning

Another way generating QR-Codes may be using Zint for 
Pascal

QR Codes in Delphi Generating and Scanning

 I think both Google Zxing bar code and onbarcode are
good, it's easily to generate QR-Code in needed
platforms.

found online Zxing qr code generator.
