Software for recognition of QR codes

A year and a half ago, I ran a post about QR codes on Habré. Today, faced with the question of the use of these and the choice of software for recognition, I want to offer the venerable public a small review of readers. I hope there will be interested as well as advanced comrades who will add useful links and reviews to the review)

So, readers.

Kaywa-reader
It seems to me the most famous.
Works on devices : Nokia, Motorola, Samsung, SonyEricsson
Recognizes the code from the monitor : with hard work
Downloaded : from mobile, from computer, via SMS
Opinion : I personally did not manage to actively do it, imo my HTC Touch is not included in the list of available devices, but I saw it in work on other phones. Perfectly recognizes a code on an uneven surface (for example, on a T-shirt).

i-Free reader?
Announced the release of the reader and fell silent. The development of events is extremely interesting ...

Our goal is to support the decoding of the QR Codes, the Data Matrix, and the UPC family of 1D barcodes.
Google did not stand aside :)

We save for now.
Until;)
