Understanding Blockchain QR Code Locking in iTraceiT: Why It Matters & How to Proceed
In the world of traceability and supply chain security, immutability is key. iTraceiT leverages blockchain technology to ensure absolute data integrity by making QR codes permanent and tamper-proof once exported
If you’ve encountered a “Parcel is Locked” message, this article will help you understand why and guide you on the best approach to move forward.
While this guarantees trust and compliance, it also means that modifications, such as merging or splitting parcels, are no longer possible after export.
Why is My QR Code Locked?
A QR Code in iTraceiT becomes locked when it is exported to the blockchain. This is not an error, it is a security feature designed to protect your parcel’s traceability. Once recorded, the blockchain ensures:
- Authenticity – No unauthorized modifications can occur.
- Regulatory Compliance – Meets industry standards for secure data storage.
- Supply Chain Transparency – Ensures all stakeholders have access to verified, unaltered records.
What You Can Do Before Exporting
Before exporting a QR Code to the blockchain, you can:
✅ Edit parcel details
✅ Split or merge parcels
✅ Make corrections or adjustments
However, after export, no modifications are possible. Any attempt to alter the QR Code will result in a “Parcel is Locked” message.
How to Proceed If You Need Changes
If you require modifications after export, consider the following options:
- Verify Status in iTraceiT – If the QR Code is still being processed and has not yet been written to the blockchain, you may be able to recall it and correct the data.
- Contact Support Immediately – If the QR Code is in transit but not yet finalized, our team might be able to intercept and cancel the blockchain export.
- Generate a New QR Code – If the QR Code has already been exported, the only solution is to create a new one with the correct information.
To avoid complications, we strongly recommend verifying all data before initiating the blockchain export.
Blockchain-powered QR codes in iTraceiT provide unmatched security and transparency, ensuring that parcel records remain unchangeable and verifiable. While this means that edits are impossible after export, planning ahead and leveraging iTraceiT’s pre-export features allow for seamless and error-free traceability. By understanding and applying these principles, you can maximize the benefits of blockchain traceability while ensuring compliance and efficiency in your supply chain.
