Virtual Shielding

Virtual Shielding™ (patent pending)

RFID is a proven technology to raise the stock accuracy and quickly get insights on the available items in a retail store…but RFID also has its challenges when it comes to determining the correct (sub-)location of an item within the store. That is because RFID can read through walls and floors – especially those thin walls that are often used in retail stores.

That means that retailers need to apply shielding to prevent ‘leakage’ and to ensure reliable insights regarding what is available on the sales floor and which items are in the stock room. As a solution, Nedap has developed the patent-pending ‘Virtual Shielding’ technology, which significantly lowers the RFID deployment & investment costs and ensures accurate sub-location information without the need to apply ‘Physical Shielding’ like aluminum foil and shielding paint in store.

How does virtual shielding work?

Virtual shielding

The smart allocation algorithm in the !D Cloud software prevents leakage and reliably determines the location of an item. Virtual shielding eliminates the high costs for physical shielding and makes it possible to easily provide actionable data to the store staff. Sub-location information is vital to be able to do refill effectively.

Physcial shielding

Metal layers can physically block the RFID signals. For this, typically aluminum foil or metallic paint is used in retail stores, resulting in material and labor of $3,000-5,000 per store. Care should be taken to apply them: even a small seam can cause a tag being read through the wall. Even if applied with the highest precision, retailers still often experience a leakage of 15 – 20% resulting in unreliable sub-location data.

During the recorded webinar, we will discuss the new Virtual Shielding algorithm (patent pending) in the !D Cloud RFID software. We will explain why shielding is necessary in RFID deployments, how Virtual Shielding works and explain why it is a great alternative to the traditional physical shielding methods.
