    Hi,
    I recently switched to this plugin (previously used another one), but both have the same issue: the QR code is generated and displayed correctly, yet the banking app cannot read it when trying to make a payment. Unfortunately, the bank app doesn’t display any error message or reason.

    Have you encountered this issue before, or do you know what might cause it?

    Thank you for your help!

    Hi,

    Thanks for considering this plugin. I have heard about it yes (I remember someone filing an issue, but can’t find it). It’s not easy to debug this, because I can’t just install any bank app. But maybe we can try to find more info.

    Can you tell me which bank app you’re using? Also, can you send me a QR code that was generated and which doesn’t work? Maybe I can test it with my bank app.

    Just found something you may use, if you can’t or don’t want to send me the QR code: https://www.mediaatelier.com/en/Tools/QRValidator/

    I just tried with a QR code myself, and it says it should contain 12 lines instead of 11. So maybe that’s the issue and some banks are more strict than others. I’ll look into this.

    Hi,
    I checked the QR code via the link provided. I get the same error:
    EPC QR Code Error
    Invalid line count
    <small>Expected exactly 12 lines, got 11. Check for missing or extra line breaks.</small>

    Thank you for looking into it.

    Regards,

    Hi,

    I’ve been looking into this. Essentially, I think the generated QR codes are valid. The 12th line is optional. But again, maybe some bank apps are stricter.

    I modified some code, and this is a QR code that gets generated when I add the 12th line (albeit empty):

    Can you check if your bank app accepts it?

    Hi,
    thank you for looking into it. I checked with my bank app.
    Unfortunately, it is not working. I get the info that the app can not read the QR code.

    Ok, good to know. I’ve learned now there are 2 versions of the SEPA QR code. Can you scan this one ? https://getpresto.be/genereer-jouw-sepa-qr-code-om-betalingen-te-ontvangen/

    That’s a V2. And to double check, this one: https://postimg.cc/mPRprNQ8 That’s also a V2, based on the V1 QR codes this library already generates.

    If those work, I’ll look at updating the code to generate V2 QR codes (which I should do anyway, just want to know).

    Strange, as these are valid QR codes. Would it be possible for you to send me a QR code that does work on your app?

    Try this one https://drive.google.com/file/d/1PsBKbs2XGFYWAql-RHsKA5RXe06SeIxV/view?usp=drive_link

    I just used it. And worked.

    Thanks, that helps! That’s actually not a SEPA QR code, but a UPN QR code, which is specific to Slovenia. You may want to check with your bank if their app supports SEPA QR codes (not all bank apps in the EU do). Technically, they’re called EPC QR codes. You can double check with the one on Wikipedia. That’s a verified QR code. If that one doesn’t work, your bank app doesn’t support SEPA QR codes. Can you let me know?

    Hi,
    yes. I took a UPN QR code because it was handy on my desk:)
    I checked the code and it did not work. I did some additional research and looks like SEPA is no longer supported. Others are also complaining in diffrent forums, different bank apps, different banks…
    I am not sure if you can help us then in any way.

    Thank you for your time for looking into this.
