Small RFID tag targeted at healthcare applications

Murata introduces the small RAIN RFID Tag at Pharmapack Europe. Created to provide a unique identifier, the tag allows RFID readers to determine the item's identity and authenticity in healthcare applications. The small and robust RFID Tags can be fitted to metallic and non-metallic surfaces, which is ideal for use on small items. To evade any risk of contamination through the drug filling operations, they can also be embedded into the product, including pre-filled syringes, vials and cartridges.

The company integrated antenna in multilayer ceramic substrates to produce a small and robust RFID tag capable of automatic identification and bulk reading of over 400units/min for high throughput efficiency. This capability enables real-time identification at full production speeds, preventing any mix-up during drug filling operations. The RFID tags also provide item-level serialisation, limiting batch segregation should a defect be found in the aftermarket.

"New regulations for product traceability and quality control in the production line from health authorities like the FDA (Food and Drug Administration) and USP (US Pharmacopeia) are driving the healthcare industry to identify and authenticate individual products from the cradle to the grave," says Teppei Miura, general manager, Murata ID Solutions. "The small RAIN RFID tag is perfect for identifying products, such as pre-filled vials and syringes and single-use injectors, during high-speed production processes as well as providing traceability for authentication in the aftermarket."

Conventional tracking of pre-filled vials and syringes needs a QR code as an applied label or printed straight onto the product's surface. Unlike RFID tags, which support bulk reading, QR codes are read individually, slowing down production. As these biochemical products need strict temperature control, condensation can also make it difficult to scan the QR code. Retrofit labels also pose a possible risk of contamination through the filling processes.

Embedding the tag directly into the component of the vial and syringe overcomes these challenges with no risk of contamination or impact on visual inspection; it also removes the process step of applying the QR code. And, as all the pertinent information remains with the item, manual input errors are eradicated.

In the aftermarket, benefits of using the tags include navigation by users, including instruction for use, and third-party drug and counterfeit drug prevention. The RFID tags can also be employed as part of the connected ecosystem to send usage data to the cloud for patient monitoring purposes for rechargeable insulin injectors.
