# Payload Changes in the QR Code * DIVOC certificates are natively digital, verifiable, digitally signed, and also printable with a secure and tamper-proof [**QR code**](/platform/divocs-verifiable-certificate-features-2.0/what-information-goes-into-a-qr-code.md)**.** * The QR [**payload**](/platform/divocs-verifiable-certificate-features-2.0/divocs-native-covid-19-certificate-specification.md) structure is based on the [**W3C verifiable credentials data model**](https://www.w3.org/TR/vc-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**](/platform/divocs-verifiable-certificate-features-2.0/what-information-goes-into-a-qr-code.md) 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. ![](/files/zQcjXurJYtPQYh5tJPBa) [![Creative Commons License](https://i.creativecommons.org/l/by/4.0/80x15.png)](http://creativecommons.org/licenses/by/4.0/)*All content on this page by* [*eGov Foundation*](https://egov.org.in/) *is licensed under a* [*Creative Commons Attribution 4.0 International License*](http://creativecommons.org/licenses/by/4.0/)*.* --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
