GroupDocs.Signature provides ability to embed into QR-code signature standard entries like email, contact v-card, address etc, WiFi, contact MeCard. This feature supports standard QR-code representation of entries. At this moment following standard QR-code entries are supported

• Email entry that allows to specify in QR-code standard email information with recipient, subject and body.
• Address entry contains address information.
• V-Card entry implements standard of visit card 3.0 specification. More details could be found here.
• Me-Card entry implements similar to V-Card contact details standard. More details could be found here.
• EPC implements standard of the European Payments Council guidelines define the content of a QR code that can be used to initiate SEPA credit transfer. More details could be found here.
• Event entry implements event standard.
• WiFi entry implements WiFI settings standard.
• SMS entry implements sms properties.
• CryptoCurrencyTransfer entry implements event standard.

Here are the steps to extract standard entry frmo the QR-code signature with GroupDocs.Signature:

• Create new instance of  Signature class and pass source document path as a constructor parameter.
• Call the generic Search method of Signature with the QrCodeSignature generic type and pass SignatureType.QRCode to it.
• Enumarate the response with the list of the [QrCodeSignature] (https://reference.groupdocs.com/signature/net/groupdocs.signature.domain/qrcodesignature/) signatures and call generic [GetData] (https://reference.groupdocs.com/signature/net/groupdocs.signature.domain/qrcodesignature/getdata/#getdata) method to retrieve the required instance of the object

Following example shows how to search for QR-code Address object in the PDF document.

using (Signature signature = new Signature("sample.pdf"))
{
    var signatures = signature.Search<QrCodeSignature>(SignatureType.QrCode);
    foreach (var qrSignature in signatures)
    {
        var address = qrSignature.GetData<Address>();
        if (address != null)
        {
            Console.WriteLine($"Found Address: {Address.Country} {Address.State} {Address.City} {Address.ZIP}");
        }
    }
}

Following example shows how to search for QR-code Email object in the PDF document.

using (Signature signature = new Signature("sample.pdf"))
{
    var signatures = signature.Search<QrCodeSignature>(SignatureType.QrCode);
    foreach (var qrSignature in signatures)
    {
        var email = qrSignature.GetData<Email>();
        if (email != null)
        {
            Console.WriteLine($"Found Email signature: {email.Address}: [{email.Subject}] : {email.Body}");
        }
    }
}

Following example shows how to retrieve contact VCard object from the QR Code signature.

using (Signature signature = new Signature("sample.pdf"))
{
    var signatures = signature.Search<QrCodeSignature>(SignatureType.QrCode);
    foreach (var qrSignature in signatures)
    {
        var vCard = qrSignature.GetData<VCard>();
        if (vCard != null)
        {
            Console.WriteLine($"Found VCard signature: {vcard.FirstName} {vcard.LastName} from {vcard.Company}. Tel: {vcard.CellPhone}");
        }
    }
}

Following example shows to find the EPC (The European Payments Council Quick Response Code) data in the QR Code from image or document.

using (Signature signature = new Signature("sample.pdf"))
{
    var signatures = signature.Search<QrCodeSignature>(SignatureType.QrCode);
    foreach (var qrSignature in signatures)
    {
        var payment = qrSignature.GetData<EPC>();
        if (payment != null)
        {
            Console.WriteLine($"EPC: {payment.Name}, IBAN {payment.IBAN}. Amount {payment.Amount}. Ref: {payment.Reference} / {payment.Remittance}");
        }
    }
}
