Use as a part of the code of Cyrillics is possible, but it is undesirable. It is connected with the fact that not all programs readers for mobile phones are capable to display it.
2. Most just the problem of conversion of text information to the QR code is solved by application of the websites which are specially intended for this purpose. Advantage of this way consists in a possibility of use of any operating system, and the shortcoming it consists in need of existence of connection to to the Internet.Dlya of to create the code this way, come on one of the following websites:
