The retail, industrial, and healthcare landscape is shifting. Retail customers look for hyper-personalised experiences and omnichannel purchase journeys, while brands grapple with agile supply chains and the looming Digital Product Passport.
The Market Landscape
The move for the “smart” industry is optimising production flows, digitalising data and regulatory compliance documents, and ease of access to these documents. Healthcare faces similar crossroads while compiling patient safety, personalised care, operational efficiency, and proposing remote therapies for chronic diseases, all while battling staff shortages.
The Technology
RFID technology, which stands for Radio Frequency Identification, has seen an increased adoption in those markets, with retail leading the way. RFID uses radio waves to wirelessly identify objects by accurately reading multiple tags simultaneously, eliminating the need for line-of-sight scanning, contrary to the barcode or QR code technology.
Two RFID technologies are used for different objectives based on the operating frequency.
RAIN RFID technology operates in Ultra High Frequency (UHF) at 860-960 MHz, allowing for longer read ranges using printers or readers. RAIN RFID technology excels in supply chain management due to its long-read range using UHF frequencies. This enables accurate stock tracking, agile supply chain operations, and error prevention through automation. The market figures confirm that:
However, dedicated readers limit RAIN RFID use in direct customer interactions.
NFC technology, operating in the High Frequency (HF) range at 13.56 MHz, leverages the ubiquity of smartphones for a shorter but highly accessible read range. This makes it ideal for B2C applications and allows for a shorter reading range, typically just a few centimetres, with high smartphone accessibility. This makes it ideal for customer- or patient-centric services, maintaining a direct dialogue between customers and brands or patients for remote therapy.
RAIN RFID-based labels register B2B product interactions. NFC-based labels register customer engagement with products. However, there is no correlation between RAIN and NFC-registered product interactions, resulting in a gap between product traceability and customer engagement. This is where the holistic product view breaks. As the date and place of product purchase are not associated with NFC “taps,” the brands cannot easily identify the specific product that sparked the customer’s interest in their supply chain.
A Transformative Approach to RFID
Imagine a world where product supply data is seamlessly associated with customer requests.
Brands have a holistic view of their product's journey to operate faster and engage smarter with customers. Customers connect to brands through products to make conscious and beneficial purchasing decisions. This is not a dream—this is a transformative approach enabled by unique RFID technology developed and produced by EM Microelectronic, a Swiss production entity.
This unique RFID technology is called RAINFC—a synergy from two abbreviations—as it uses the synergy of RAIN and NFC worlds. RAINFC merges the benefits of RAIN RFID and NFC into a single integrated circuit (IC) and allows the exchange of information between two interfaces through a shared IC memory. The heart of RAINFC is the IC branded by EM Microelectronic em|echo-V.
em|echo-V integrated into product labels allows holistic 360° product journey visibility and correlates product data gained from RAIN RFID and NFC interfaces. It unlocks a world of possibilities in retail, industrial, and healthcare. Streamlined operations and automated data flow, agile supply chains, personalized customer experiences, or remote patient services are now accessible with a single product label.
The shared IC memory encodes product labels using RAIN RFID, HF printers, readers, or even smartphones for small tag batches.
The role of SATO printers in activating the em|echo-V-based labels
Printers play a vital role in enabling RFID technology directly in healthcare and retail production facilities (“source tagging”). RFID printers streamline the source tagging process by integrating printing and encoding, eliminating the need for separate encoding steps. This improves efficiency and reduces the risk of errors that might disrupt the production process.
SATO offers a range of RAIN RFID and HF printers specifically designed for retail, healthcare, and smart industrial applications. EM and SATO are delighted to announce that the CL4NX and CL6NX Plus RFID printers now fully support the printing and encoding of RAINFC labels.
Printers will encode the tags with em|echo-V at high speed using the UHF interface and print them in a factory or warehouse. When it comes to limited volumes or specific orders, the compact CT4-LX desktop printer will be an ideal solution. SATO offers a print-and-verify solution for its printer line to ensure printed tags are properly read.
When deploying RFID, businesses can choose to introduce a new management system or integrate it into their existing supply chain systems. With SATO printers, native support for Loftware Cloud and NiceLabel allows for tag printing and encoding that integrates easily into existing barcode printing workflows. It is highly scalable for global deployment and has the highest level of security, SOC 2 Type II.
With the SATO labelling solution, businesses can easily define the data that needs to be written to the RAIN memory and the data meant for the IC's NFC memory. This covers Electronic Product Code (EPC) conversion and the generation of the NDEF message. EPC is used in inventory control and real-time product traceability, while the NDEF format stores and exchanges information like URLs and plain text, which can be used for consumer engagement.
