Mr. Li Lin, General Manager of R&D department, explains: The Voyantic Tagformance systems with anechoic chambers are used in the design lab for evaluating the inlay designs. The Tagformance systems are also used in sample testing the tag performance and quality of manufactured tags. With the systems, we can verify all the essential parameters such as tag sensitivity.

The Voyantic systems are precise and easy to use. Their quality is excellent. We have had the Tagformance lite system for a long time already, and there have been no failures, it is still working very well. Mr. Li Lin tells.

Mr. Zhou Senmao, Manager of QC department, continues: The Voyantic Tagsurance systems are used in quality control during production, in-line at the production machines. In the quality testing, the tag performance is checked at a few critical frequencies, this procedure assures that each tag works as specified. The Tagsurance systems are also used in separate off-line QC tests.

Voyantic Tagsurance UHF systems have been used for verifying the consistency of the UHF tag quality. The systems are fast. They are used in manufacturing lines running at high speeds without any misjudgments. And all the data is saved in real-time.

The systems have helped to improve the quality inspection accuracy, and at the same time greatly improved the efficiency of the QC. Now our quality is excellent and also our production yields have increased. Mr. Zhou Senmao describes.

Xindeco IOT teams are continuously developing manufacturing and quality control activities. The latest developments include improvements in HF RFID quality testing, and combining Tagsurance based RF-testing with Automatic Optical Inspection (AOI) equipment.

We hope that in the future Voyantic would be even more involved in training us, and together we could find still new ways to improve our manufacturing and quality control. Mr. Li Lin visions the future.

Cooperation between Voyantic and Xindeco IOT will continue strongly.


Since its establishment in 2004, RFCAMP Ltd. has been the leading Korean RFID specialty tag provider with a 50% market share in on-metal applications. The company has exported tags branded “Titan” to more than 40 countries.

“Annually, we are engaged in more than 200 RFID projects all over the world, and each project – or each customer – needs tags that are best fit for their environment. We, therefore, strongly feel that the specialty tag business is rather of service, not production” says Jerry Ryu, the Founder and CEO of RFCAMP. “In order to satisfy our clients, we must prove that the tag we suggest truly is best fit for the required environment, and we believe the use of Voyantic’s Tagsurance is the most reliable and persuasive way”.

“When we get a call from a customer concerning tag performance, we set up a similar environment internally, measure the tag sensitivity with the Tagsurance and send our report to our customer. At that time most customers become convinced.” “If the issue is more serious, we pack the Tagsurance and visit the RFID site to measure and test the tags in front of our customers, which has helped RFCAMP become a more reliable supplier”.

“For the tag business, Voyantic’s products are needed for the tag development and production. However, they are needed the most when interfacing with a customer” says Jerry Ryu.

SAG – Ensuring Efficiency in R&D and Quality in Production

During the past two decades, SAG has positioned itself from an RFID transponder manufacturer to the solution provider. “Back in 2017, we became an alliance member at RAIN RFID, which advocates UHF technology. Seeing the growing demand for RFID transponder targeting at the theme of IoT and Industry 4.0, we are proud to bring our know-how and expertise for customization and end-to-end production capability for realization. Our breakthroughs happen in many applications from different sectors. We came up with the hard tag which goes to the dense metal environment for industrial purpose. We introduced a label which ignores water interference for health care consumables. We brought card and wristband that sees no reading distance drop on the human body to realize hands-free applications for gateway passing. And we customized one tag for both metal and non-metal asset management to benefit the logistic world. We are capable of taking out the hiccups people face when they plan to implement RFID but the environmental challenges just don’t agree”, says Mr. Terry Chiang, General Manager.

“We use Tagformance during product development and Tagsurance for quality assurance in mass production because Voyantic is the most trusted and reliable equipment for RAIN RFID product inspection. Tagsurance is used to inspect the electric performance for HF and RAIN RFID product while Tagformance is to check the reading distance of RAIN RFID product.”

“Tagformance assists our antenna design job with great efficiency and this is very important for product development. On the other hand, Tagsurance plays an important role in quality assurance because it detects a tag’s electrical performance by providing multiple frequency points. This is different from the traditional Go/No-Go test which relies on a single frequency value. “, explains Mr. Terry Chiang, General Manager of SAG.

“We are happy with the excellent service such as onsite training and prompt response to our questions when we operate the systems. Voyantic system facilitates our product development and mass production. The obtained data has great value in guiding us to correct and improve a product’s performance so as to satisfy our customers”, continues Mr. Terry Chiang, General Manager of SAG.

SAG Technical Manager Mr. Kevin Kuo is happy about the efficiency improvement that Tagsurance HF has brought into SAG production line. He says:

“Tagsurance HF testing speed is much faster than normal commercial HF reader. The UPH has been increased over 200% after Tagsurance HF replaced the commercial reader in our converting line. Tagsurance HF can sort out those weak performance tags that a normal reader is unable to achieve. More importantly, Tagsurance can also record each tag minimum turn-on power which is very useful information for our engineers to adjust the machine manufacturing parameters and to enhance the tag quality control.”

AML Research Laboratory Uses Tagformance to Test and Verify UHF RFID Tag Designs

Founded in 2000, AML is a research laboratory of Electronic Communication Engineering at the National Kaohsiung University of Science and Technology in Taiwan. Over the years AML has specialized in antenna design applied to consumer electronics such as mobile phones and notebook computers.

In 2009 AML came across Voyantic’s solutions when focusing on high-quality RFID tag and reader antenna designs.

Before 2009, AML measured tag antennas in a chamber and was able to only measure the antenna gain and efficiency. The challenge was that AML could not provide the tag dynamic characteristics to commissioning company. To solve the problem, AML started using the Voyantic equipment for RFID testing and measurement to achieve the next big milestone in RFID tag design.

AML uses Voyantic Tagformance hardware and software to measure if their UHF tag designs meet the specifications provided by the commissioning company and to gain visibility into the quality of each tag.

AML also uses Tagformance for research and development when designing a new tag.

“Tagformance is extremely fast, reliable, and accurate in the operating process. Apart from laboratory measurement, it is also very useful for testing RFID tags in a real operational environment. We are fully satisfied with the service, long-term support and assistance offered by the Voyantic team”, noted Jui-Han Lu, Professor at the University

Smartres — Production of High Performance RFID with High Efficiency

Smartres is a well-known Italian RFID tag R&D center and manufacturer. The company has developed its own patented solution to create inlay-less products using technology with chip-on-strap coupled with copper wire antenna. The process provides eco-friendlier products compared to traditional processes, with best in class RF performance. After ten years of experience in manufacturing, utilizing their own designed machinery, Smartres decided to take a step forward. A4IS was commissioned to build a new manufacturing line based on the Smartres process, design, and previously built know-how.

Automation 4 Industrial Solutions (A4IS) is a new company dedicated to the creation of automatic manufacturing lines for various industries and specifically for the RFID world. Smartres have now started to use this new machine called FTL6000 in their own production, where they are producing both HF/NFC and UHF tags.

RFID Tag Variety and Selection

Amongst the various types of tags offered to the market, UHF RFID tags are widely used in various market segments and applications such as Fashion, Logistics, Waste Management, Tires Tracking, and many more. Various antenna form factors and technics, as well as several chips, are used to tailor the best suitable solution for each application.

“For designing the antennas for our tags, the Voyantic Tagformance has been a priceless tool, which has saved us time and given our engineers the chance to get things done efficiently and with high confidence.” says Luigi Radaelli, CEO at Smartres.

“Easy to use and effective in validating the selected antenna profile to get the desired performance, Tagformance is the ideal device for the RFID designer”* confirms Davide Bergamini, Smartres CTO.

How to Provide “100% Performance Tested RFID” Efficiently?

Being able to tailor the best tag for each application purpose is one thing. What becomes at least as an important factor for guaranteeing a faultless RFID system, is that each delivered tag meets the designed performance. The only way to assure this is to verify the performance level of the produced RFID tags by 100%. With a wide banded component like a UHF tag, this cannot be done by checking the tag functionality on one frequency only, but accurately measuring the required wake-up power on multiple frequencies throughout the tag’s frequency band.

The most efficient way of monitoring product quality in a reel to reel manufacturing line is to produce RFID tags and have them tested in the same process. This allows reacting immediately to any changes in the RF performance of the process outcome. Having the testing inline instead of having it offline as a separate testing process, not only avoids large scale rework but also enables one process less. This means less machinery, fewer work hours, and less handling of the reels and having the risk of accidentally damaging the tags. In the end, this all comes down to delivering high-quality tags, with 100% measured and proven RF performance, efficiently.

This Is How to Do It!

As said before, RFID tag quality is mandatory, and the 100% supply of UHF RFID products performing within the specifications tolerances is specifically what the market looks for. To be able to grant this, on top of having the most efficient and reliable tag assembly operations, Smartres and A4IS decided to put in line the measurement of the response curve of the tags by adopting the Voyantic Tagsurance Tester, a state of the art device. With Tagsurance, each UHF RFID tag produced is checked against specifications and validated whether it’s good or not and instead of just marking the failed tags, also the performance level measured is recorded for each tag. These recorded log files give true traceability to the production quality data also afterward.

“Having the Voyantic Tagsurance in our manufacturing for some years already has given us a great advantage for process development and helped us to achieve a world-class high precision production process. We are delivering over 30 million UHF tags yearly with measured quality, yet produced with the best efficiency and minimum labor cost.” says Federico Chiesa , Smartres Operations Manager, going on with: “The in-line adoption of the Tagsurance allows avoiding any additional off-line operations. This minimizes the extent of damage caused by any errors and mistakes like poor raw material quality, process parameters or parts wearing, as any fault can be spotted immediately. It’s a valid support for the machine operator who has the live visibility of the machinery performance, allowing immediate action for any adjustment, resulting in the best possible efficiency. With a highly automated process as ours, part of the efficiency comes from the fact that only one operator is required to run two machines.”
