Pharma Company Cuts Relabeling Time from 2 Months to 1 Day with Digital Display Labels

We began with component selection to ensure every part met pharmaceutical regulations and tolerated sharp temperature swings.

First, we chose e-ink displays (as in e-readers) for energy efficiency and readable text.

We then selected compliant components: battery, chip, and electromagnetic shielding materials that meet both EU and US standards.

Finally, we built functional prototypes and successfully tested them in real-world conditions.

Next, we developed firmware that connects directly with provisioned mobile devices via NFC.

When the device scans the label, the firmware authenticates the connection, writes the updated expiry or batch data, verifies integrity with checksums, and refreshes the e-ink screen in a few seconds.

To make on-site relabeling simple and auditable, we developed a mobile app that communicates with each label through NFC.

Clinical staff can update hundreds of IMP kits in minutes, and every action is automatically logged for traceability.

We connected the labeling system with the client’s clinical inventory management system, so every label update is synchronized with the central database in real time.

This integration ensures that all label changes, expiry extensions, and site actions are fully visible to quality and supply chain teams.

Finally, we validated the entire system under GxP and data integrity standards, ensuring alignment with FDA 21 CFR Part 11 and EU GMP Annex 11.

We conducted internal audits and passed verification reviews, confirming that every component met regulatory expectations.

After successful prototype testing, we connected the client with a trusted manufacturing partner. Now, our client is actively scaling production for wider use across trial sites.

The results are already promising: relabeling time has reduced from 8 weeks to around 24 hours with our custom digital labels, and there are no additional costs for logistics or product replacements.
