Swiss QR Invoice

[Schumatech]

Hello everyone,

Who has already generated a Swiss QR- invoice with Lucee? Which components/libraries or services have you used?

I am of course looking for something that is free of charge. It is for a non-profit organization.

I would be very happy to receive tips and advice.

Thanks a lot,
Allan

see this post it shows how to make QR code with Lucee 6.2

Interacting with Java Libraries in Lucee 6.2

With Lucee 6.2, one of our main objectives was to simplify Java integration as much as possible. We focused on making it easier to load libraries and adapt existing Java code to work seamlessly in Lucee. To achieve this, we approached it with a simple challenge: pick a third-party Java library and try to use it in Lucee with the least amount of friction. If we encountered any hurdles, we adapted Lucee accordingly. In short, we learned a lot from real-world examples and worked to overcome any une…

Of course it can be rewritten to work with older Lucee versions, but will need a bit of work.

@Schumatech, I was not familiar with the Swiss QR Code, but was curious so I just learned about it and found that it has a specific data content structure for payment info, plus the Swiss cross in the middle for user recognition, but structurally not different than any other QR code.

As for data structure, I found multiple versions here.

Then using @micstriit’s Java example as a reference, I herded ChatGPT into giving me cfscript that looks like it could actually work (I haven’t tested it):

// Load necessary ZXing Java classes
qrWriterClass = CreateObject("java", "com.google.zxing.qrcode.QRCodeWriter");
bitMatrixClass = CreateObject("java", "com.google.zxing.common.BitMatrix");
encodeHintType = CreateObject("java", "com.google.zxing.EncodeHintType");
barcodeFormat = CreateObject("java", "com.google.zxing.BarcodeFormat");

// Swiss QR Code payment data (adjust based on Swiss QR Code standard)
qrData = "SPC\n0200\n1\nCH4431999123000889012\nS\nRobert Schneider AG\nRue du Lac 1268\n2501\nBiel\nCH\nS\nPia-Maria Rutschmann-Schnyder\nGrosse Marktgasse 28\n9400\nRorschach\nCH\n3949.75\nCHF\n\n\nNON\n\nMOTIVATED SALARY";

// Set QR encoding hints
hints = CreateObject("java", "java.util.HashMap");
hints.put(encodeHintType.CHARACTER_SET, "UTF-8");

// Create the QR code BitMatrix
qrCode = qrWriterClass.init().encode(qrData, barcodeFormat.QR_CODE, 400, 400, hints);

// Load BufferedImage for handling the QR code image
bufferedImageClass = CreateObject("java", "java.awt.image.BufferedImage");
bufferedImage = qrCode.toBufferedImage();

// Swiss Cross Image (see download below)
crossImagePath = "/path/to/swiss_cross.png";
imageioClass = CreateObject("java", "javax.imageio.ImageIO");
crossImage = imageioClass.read(CreateObject("java", "java.io.File").init(crossImagePath));

// Combine Swiss Cross into QR Code Image
graphicsClass = bufferedImage.getGraphics();
crossWidth = 50; // Set size for the Swiss cross
crossHeight = 50;
crossX = (bufferedImage.getWidth() / 2) - (crossWidth / 2); // Center position
crossY = (bufferedImage.getHeight() / 2) - (crossHeight / 2);

// Draw the Swiss cross in the middle of the QR code
graphicsClass.drawImage(crossImage, crossX, crossY, crossWidth, crossHeight, null);
graphicsClass.dispose();

// Save the QR code image to a file
outputPath = "/path/to/output/swiss_qr_code.png";
outputFile = CreateObject("java", "java.io.File").init(outputPath);
imageioClass.write(bufferedImage, "png", outputFile);

// Output success message
writeOutput("Swiss QR Code with Swiss cross generated successfully.");

I also found a PNG for the cross here via Formpipe.

Good luck and I’m looking forward to your QA tested code!

I think there is not such a thing as a swiss QR-Code. QR-Codes is a free to use patent (thx to Denso and Toyota). What you are describing is a standard of structered information that is the content of the QR-Code. You just need to bring the raw data into the needed standard and translate/generate that to a QR-Code like any other standardized data (such as e.g. vcf, url etc)

This could be a helpful link. Do you have any more information on how it can be used

[andreas]

I’ve read something about it. The QR-Bill is not just a QR-Code, but a standard for printing standarized digital bills (e.g. as PDF) in a structured manner, that has t the QR-Code data in it (as XML). You can choose to make it fully by your own, or try using a linary for it, e.g. SwissQRBill Java library GitHub - manuelbl/SwissQRBill: Java library for Swiss QR bill payment slips (aka QR-Rechnung)

QRCode can store 4 kind of that, binary,string,number or kanji (japanese characters).

Nearly all QRCode today do store string and use different formats QRReader understand, i have for example a component that can create for me all kind of format like this

        /**
         * Creates a formatted WiFi configuration string to encode into a QR code.
         * 
         * @param ssid          The WiFi SSID (network name).
         * @param password      The WiFi password.
         * @param encryption    The encryption type (e.g., WPA, WEP). Optional.
         * @return              A formatted WiFi string for the QR code.
         */
        public static String function wifi(required string ssid, required string password, string encryption="") {
            var enc="";
            if(len(arguments.encryption)) enc="T:#arguments.encryption#;";
            return "WIFI:S:#trim(arguments.ssid)#:;#enc#P:#arguments.password#;;";
        }

for “Swiss QRCode” this is simply a format like this, sorry i simply assumed that part is clear.
