• DIVOC certificates are natively digital, verifiable, digitally signed, and also printable with a secure and tamper-proof QR code.

• The QR payload structure is based on the W3C verifiable credentials data model.

• Previously, any changes in the QR payload required changing it in the certificate-signer service and subsequent deployment.

• With DIVOC 2.0, QR payload changes can now be made by changing it in etcd without any deployments.

• Currently, only the optional fields that already exist can be removed. New fields cannot be added as of now.

• Note: Do not remove the mandatory fields.

Steps to remove an optional field:

• Go to DDCC_TEMPLATE. Click on the Edit key if you want to remove an optional field.

• Click on Save. A popup will appear as “operation successful.” Click on Close.

Run the command: vim DDCC_TEMPLATE.template.

To reflect the change, run the command: ./updateConfigs.sh. It shows "OK OK OK...." This means that etcd has been updated with the new QR Code template successfully.
