Implementation Guide

Create HIBC LIC Primary Data

Overview: This section demonstrates how to create and configure an instance of HIBCLICPrimaryData, which holds essential product information.

Step 1: Initialize Primary Data Object

HIBCLICPrimaryData primaryData = new HIBCLICPrimaryData();

Step 2: Set Essential Properties

  • Product or Catalog Number: Unique identifier for the product.
  • Labeler Identification Code: Identifies the manufacturer.
  • Unit of Measure ID: Specifies measurement units.
primaryData.setProductOrCatalogNumber("12345");
primaryData.setLabelerIdentificationCode("A999");
primaryData.setUnitOfMeasureID(1);

Create HIBC LIC Secondary Additional Data

Overview: This section covers creating and configuring an instance of HIBCLICSecondaryAdditionalData, which includes additional details like expiry date and lot number.

Step 1: Initialize Secondary Data Object

HIBCLICSecondaryAdditionalData secondaryData = new HIBCLICSecondaryAdditionalData();

Step 2: Set Additional Properties

  • Expiry Date: Use current date for demonstration.
  • Quantity, Lot Number, Serial Number: Define product specifics.
  • Date of Manufacture and Link Character: Establish manufacturing details.
secondaryData.setExpiryDate(new Date());
secondaryData.setExpiryDateFormat(HIBCLICDateFormat.MMDDYY);
secondaryData.setQuantity(30);
secondaryData.setLotNumber("LOT123");
secondaryData.setSerialNumber("SERIAL123");
secondaryData.setDateOfManufacture(new Date());
secondaryData.setLinkCharacter('S');

Combine HIBC LIC Primary and Secondary Data

Overview: Learn how to merge primary and secondary data into a single HIBCLICCombinedData object for streamlined processing.

Step 1: Initialize Combined Data Object

HIBCLICCombinedData combinedData = new HIBCLICCombinedData();

Step 2: Set Primary and Secondary Data

  • Link both datasets to form a complete data structure.
combinedData.setPrimaryData(primaryData);
combinedData.setSecondaryAdditionalData(secondaryData);

Sign Document with QR Code Containing HIBC LIC Combined Data

Overview: This final section demonstrates how to sign a document using a QR code that encodes the combined HIBC data.

Step 1: Define File Paths

String filePath = "YOUR_DOCUMENT_DIRECTORY/Sample.pdf";
String outputFilePath = "YOUR_OUTPUT_DIRECTORY/SignWithQRCodeHIBCLICCombinedData/" + fileName;

Step 2: Set Up QR Code Sign Options

  • Encode Type: Use QrCodeTypes.HIBCLICQR to specify the encoding type.
  • Data Assignment: Pass combined data for inclusion in the QR code.
Signature signature = new Signature(filePath);
try {
    QrCodeSignOptions options = new QrCodeSignOptions();
    options.setEncodeType(QrCodeTypes.HIBCLICQR);
    options.setData(combinedData);

    // Sign and save document
    signature.sign(outputFilePath, options);
} finally {
    if (signature != null) signature.dispose();
}

Practical Applications

  1. Pharmaceutical Compliance: Streamline compliance with regulatory standards using this integration.
  2. Supply Chain Management: Enhance traceability of pharmaceutical products through QR codes in documents.
  3. Healthcare Systems Integration: Embed comprehensive product data within healthcare records for better patient safety.

Performance Considerations

  • Optimize Resource Usage: Ensure efficient memory management by disposing of the Signature object post-operation.
  • Best Practices: Regularly update to the latest GroupDocs.Signature version for performance improvements and bug fixes.

Conclusion

By following this guide, you have learned how to create HIBC LIC primary and secondary data objects, combine them into a single entity, and sign documents with QR codes using GroupDocs.Signature for Java. These skills enhance document security and ensure compliance in the pharmaceutical industry.
