Modum System


The regulations outlined by the European Commission for the Good Distribution Practice of medicinal products for human use (GDP 2013/C 343/01) were published on November 5, 2013. Chapter nine of this regulation requires proof that shipped medicines have not been exposed to conditions, particularly temperatures, that may compromise their quality. These regulations are now enforceable across Europe. offers an alternative supply-chain solution, ensuring GDP compliance and auditability by using blockchain and IoT technology. modum’s passive temperature-monitoring strategy offers significant cost savings over the active-cooling methods currently used.  Additionally, through the use of cutting-edge technology, valuable data can be created to drive continuous improvement in supply-chain logistics.


The modum sensors record environmental conditions during shipments. When shipped goods change ownership, the collected data is checked against a specific smart contract in the blockchain. The contract validates that the transaction meets all of the standards set out by the customer, their clients or the regulator and triggers various actions: notifications to sender and receiver, payment, or release of goods, etc.


Using the data collected by modum’s services, the opportunities for improving the supply chain in any sector in terms of efficiency, cost reduction, environmental impact, customer service, and regulatory compliance are limitless.


1. Smart contracts

Smart contracts are a verified set of parameters that are publicly accessible on the blockchain. Instructions within the smart contract can prompt actions within a supply chain. Currently, our clientele in pharma and pharma logistics use our smart contracts to store temperature alarm criteria for the pharmaceuticals in transport. If temperatures beyond the thresholds are registered, a notification is sent to the sender and receiver.

2. IoT sensor devices

These are fully programmable devices which allow a range of environmental factors to be measured for a parcel or package. Sensor devices can easily be activated and connected to a shipment and can be programmed in advance. So far, modum’s sensors have measured over 500,000 data points for pharma pilot customers.

3. Smart phone application

Our application allows an easy integration into regular operations. By scanning the sensor’s QR code and the package’s tracking number the sensor can be easily connected to a parcel with alarm criteria set remotely. The application also allows the receiver (end user or logistics provider) to retrieve environmental data and subsequent notifications without opening the package.

4. Dashboard

The dashboard provides back-end analytics for all shipments carried out with the modum system. It allows pre-configuring settings for specific products. Additionally the dashboard enables filtering and bulk analysis of shipments and can automate further actions such as notifications, product return, or reshipment in case of deviations.


The modum system can be easily integrated into existing logistics processes: In advance of shipping, quality assurance managers set the approved temperature ranges for each product. This initial step can be done remotely, using the dashboard.


In the warehouse, a unique shipping ID for each parcel is paired with a modum temperature logger. The combined temperature range for the shipment, shipping ID and sensor ID are used to create a specific smart contract for each shipment.


During shipment, the sensor tracks the temperatures. When the shipment changes ownership the data can be readout using Bluetooth, enabling a compliance check without opening the parcel.


The modum system has been validated through pilot programs throughout Europe and the Middle East. These programs have served 43 companies in tracking almost 1,000 shipments with over 500,000 data points.

Pilot 1.0 monitored shipments between the Swiss companies Schaer Pharma and Voigt AG for a duration of six weeks whereby 17 sensors tracked 10,000 data points. The results of the pilot lead to improvements of the sensor device, an increase of the transfer speed, and the development of a web client.

Pilot 2.0 included partnerships with pharmacies and clinics in order to scale shipment volume and to test our service in different distribution networks. used the TI Sensor Tag for the pilots. monitored international shipments between Europe and the Middle East, testing an adapted value proposition: the provision of data for improving the quality assurance aspect of the supply chain.

The final pilot involved a logistics service provider market leader and a mail order pharmacy to prove the suitability of the modum system for large-scale use. The achieved sensor read-out time was less than 8 seconds on average. Players recommended the integration of the modum system into the offering of the logistics service provider. Sensor read-outs were attained in less than 8 seconds on average.
