Hi Juraj,
a QR code is a bidimensional barcode.
My printing library has the needed functionality, so I can simply use it.
But there seems to be something on CodeProject:
www.codeproject.com/Articles/1250071/QR-...T-Class-Library-Writ
Or something other:
csharp.hotexamples.com/de/examples/ZXing...-class-examples.html
Basically you should generate a bitmap from your text and print it then with your printing library.

Hi Wolfgang,

to add it, I do not need to print QR codes, I need to generate a picture (bitmap) that the program will send electronically to the customers who will make payments based on this code.
Where would I find what QR code should contain for the payment, especially in what structure. I found more libraries for creating QRs, but I'd like to save time by testing and letting you know which one to use.

Hi Juraj,
as I wrote: my printing library generates them, and therefore I have never researched other sources.
Anyway: the ZXing library seems to be one of the most used in .NET:

Hi all,

using zxing i can generate a QRCode, but i can't find anywhere to create a pay "string" for payment. Does anyone know how to do it?

Juraj,
didn't you look in my links on wikipedia? AFAIU, there the "strings" are listed, no?

Hi Juraj,

unfortunately I don't know what contents are neded in your country for payments. You need to ask a bank or look at other codes with your smartphone.

Hi Karl,

at least here I have never seen SEPA payment requests with QRcode.
And my bank has no QRCode reader....

Wolfgang,
obviously noone bothers to read my link ;(.
"EPC QR code From Wikipedia,
The European Payments Council Quick Response Code guidelines define the content of a QR code that can be used to initiate SEPA credit transfer (SCT). It contains all the necessary information in clear text. These QR code guidelines are used on many invoices and payment requests in the countries that support it (Austria, Belgium, Finland, Germany, The Netherlands) enabling tens of millions to pay without requiring manual input leading to lower error rates."
Followed by a description and samples...

Hi All,

Wolfgang is right, probably in individual countries. I found the SEPA payment in Czech but the QR code with Czech pay "string" not work. . When I made a QR code on web page, work OK. I gave it a decode (with gxing) pay "string" has this content:

pay "String" from QR after decode:
00064000BQPSCJSHJL6A1D2DR3GGLFQL4L7GK8KUF7N3THCK4DNA237JJI27CROV2J73ECSGR1IB357DO

original pay data :
IBAN: SK6381805002408134378929 VS: 1100022019 KS:1144 Amout: 1985,74 EUR Due Date: 25/3/2019
