Swiss QR

Overview

The parser supports the 1.0, 2.0 and the 2.1 versions of the Swiss QR ISO 20022 standard. For the complete documentation of the standard please refer to the official website.

Sample usage for SwissQr parser and Barcode Capture

First, you need to create a DataCaptureContext, access a Camera and create SwissQr parser:

const context = Scandit.DataCaptureContext.forLicenseKey("-- ENTER YOUR SCANDIT LICENSE KEY HERE --");
const camera = Scandit.Camera.default;
context.setFrameSource(camera);

const cameraSettings = new Scandit.CameraSettings();
cameraSettings.preferredResolution = Scandit.VideoResolution.FullHD;
camera.applySettings(cameraSettings);

const settings = new Scandit.BarcodeCaptureSettings();
const barcodeCapture = Scandit.BarcodeCapture.forContext(context, settings);

let parser;
Scandit.Parser.forContextAndFormat(context, Scandit.ParserDataFormat.SwissQR).then(p => {
  parser = p;
  parser.setOptions({minimalVersion: 100});
});

Then, you need to implement BarcodeCaptureListener:

const barcodeCaptureListener = {
    didScan: (_, session) => {
        const barcode = session.newlyRecognizedBarcode;

        // Parse the scan result.
        parser
            .parseString(barcode.data)
            .then(result => {
                const fields = result.fieldsByName;

                /*
                * Extract the fields relevant to your use case. Below, for example, we extract a creditor's name,
                * which has the type String, and a due date, which is represented as a map with keys
                * "year", "month", "day".
                */
                const creditorName = fields['QRCH/CdtrInf/Cdtr/Name'].parsed;

                const dueDate = fields['QRCH/CcyAmtDate/ReqdExctnDt'].parsed;
                const {year, month, day} = dueDate;

                // Do something with the extracted fields.
            })
            .catch(error => {
                // Handle the parser error
                console.log(error.message);
            });
    }
};

Finally, add the listener to the mode to receive scan results:

barcodeCapture.addListener(barcodeCaptureListener);

For details, go to the API docs.

Example

Parsing following, SwissQr version 1, code (without quotes):

"SPC\r\n0100\r\n1\r\nCH6812345678901234567\r\nScandit AG\r\nLimmatstrasse\r\n73\r\n8005\r\nZuerich\r\nCH\r\n\r\n\r\n\r\n\r\n\r\n\r\n1234.00\r\nCHF\r\n2020-01-01\r\n\r\n\r\n\r\n\r\n\r\n\r\nNON\r\n\r\ntest code\r\nAC:Alternative scheme data first\r\nAC:Alternative scheme data second"

will result in following JSON output:

Parser Options

The parser can be configured by providing a JSON string containing key / value pairs. The following configuration options are available:

Key

Value Type

Description

minimalVersion

Int

Sets minimal version of Swiss Payment Standard that will be parsed. Available options are: 100 (1.0 version), 200 (2.0 version) and 210 (2.1 version). By default it is 200.

strictMode

boolean

Controls the strictness of the parser. When strictMode is set to false, parsing continues for non-critical errors (missing required field, fields containing incorrect characters, invalid separator or character etc.). The encountered problems can be queried via the issues property. By default option is set to true.

Strict Mode

By default the parser operates in strict mode - that means parsing is going to fail whenever the parsed code deviates from the standard.

When strictMode is set to false, parsing continues for the following non-critical errors:

  • A mandatory field is empty or missing;

  • The code mixes CR + LF and LF separators between elements;

  • QRCH/CcyAmtDate/Ccy (currency) contains non-alphanumeric characters or is of incorrect length;

  • QRCH/CdtrInf/IBAN (IBAN) contains whitespace characters;

  • PstCd (postal code) and/or TwnNm (town) are present for an address defined as combined (“K”).
