Interview – “Mr. RFID”, Henrik Granau (Part 2)

Welcome to Part 2 of my interview with Henrik Granau, or more correctly, Mr. RFID. If you haven’t read Part 1, I urge you to do that, to get a good understanding of Henrik, RFID and its challenges. Simply click here!

If you already have read Part 1, I love that you did, then you know that this part is going to focus on the opportunities with RFID within food traceability/transparency. No more small talk, let’s dive into it!

And then turning from the challenges, what are the general opportunities with RFID?

There are a lot of application areas and certain Industries where there are still obvious opportunities, but in general I believe it is in the combination with other technologies we see the huge potential;

By using RFID you create a transparency on how goods, assets etc. are flowing through your operation and if you add to this detailed information on how the workflow is actually being performed, you have established the foundation of making better decisions in your organization.

When combining these operational data with other data (‘Big Data’) and Software Robots (Artificial Intelligence), you can create new services and business models (‘disruption’).

Almost everything within the area of ‘Internet of Things’ involve wireless communication with a device which has to be uniquely identified to make sense – hence “RFID” will be ‘pervasive’.   

Building on that, from your knowledge, what are the potential of RFID tags to create greater traceability of food products and why?

Internationally we already have a number of good cases in food traceability (Fish, livestock, vegetables) with RFID and combined with temperature sensors, we have established better cold-chain management. I believe that traceability within the supply chain can still be improved, but in general the technology is in place and we have the good cases with documented results.

The challenge is that we want the consumers to be able to have the complete history of each item available on their smartphone with one scan. If it’s RFID (NFC) or 2D barcode doesn’t matter so much – the challenge is to capture all the information during the product’s lifetime automatically which is achieved by using RFID on the transportation unit. For this to work, the unique item numbers which are packed has to be associated with the unique identifier of the transportation unit, and in some areas you will then have to add some evidence that the goods hasn’t been tampered with during transportation.

So creating greater traceability is possible with RFID, but you have other issues depending on the objectives; 1) for manufacturers to issue effective recalls, 2) for consumers to check the goods before consumption, 3) for protecting against fraud, etc.  

What potential do you see in a RFID/Blockchain combination to create greater traceability of food products, from your knowledge?

I am not a blockchain specialist, but I understand that what blockchain can add is a bulletproof distributed verification mechanism. So, when the issue is to have verification that a specific organization is guaranteeing that their part of the traceability data are valid, then you could use blockchain to lock a certain ‘hand-over’ transaction with some associated data. If RFID is used then this process could be done automatically at choke points. As an anti-counterfeit method.

I believe I can learn more about the potential with RFID/Blockchain by being kept updated on your progress.

If someone was interested in RFID, what would be a few things you would suggest to investigate further?

I will start with recommending to vist This is RFID I Danmark’s website where we have tried to give a good introduction to RFID – especially through cases and slides from presentations held at our conferences.

As a special service the RFID I Danmark Association is offering that anyone for free can contact me with initial questions. You can mail me at or you can call me at +45 21 832 835.

Thank you to Henrik, for his great insights into RFID and the opportunities. From this and what I learned from the RFID in Denmark conference, I see great potential for a RFID/Blockchain solution in supply chains. RFID will secure correct data inputs, which can’t be tampered or adulterated, which then are data inputs for the immutable blocks in the blockchain application.

One of the key takeaways from the conference, was the lack of adoption and their one-sided focus on RFID being a inventory solution, and not grasping a more holistic picture of what the tech can do. And I feel that, that is a general thing when investigating new technologies, that it is very one-sided and not trying to connect all the dots.

Thank you reading, have a great day!
