Mounted metal RFID tag performance higher floor

Beijing, China, October 12: Radio frequency identification (RFID) technology for ultra-high frequency (UHF) applications is always difficult to match with metal products or metal environments, like the relationship between oil and water, which makes it possible to manage RFID technology. The retail supply chain (RSC) of metal products faces severe challenges. In response to these challenges, Sontec, the leading developer and manufacturer of RFID component and middleware products in South Korea, has announced the launch of several RFID tags and metal-mounted RFID transponders using Texas Instruments’ EPC Gen 2 IC chip.

According to the current agreement between TI and Sontec, TI will provide 10 million radio frequency identification (RFID) Gen 2 chips to Sontec. The first shipments have been delivered and the rest will be delivered before the first half of 2007. Sontec's new RFID transponder achieves higher read range performance, which in turn helps suppliers optimize a variety of consumer product supply chains, including home appliances, electronics, and products with high metal content. Sontec's target customers for this primary product are limited to Asian home appliance and electronic equipment manufacturers, but its final product will be sold to the global retail market including Japan and the United States.

Generally speaking, radio waves emitted by RFID tags are reflected by metal at the UHF frequency band, and the eddy current effect generated by metal products also causes attenuation of the radio waves, which reduces the reading distance performance. For retails that require a reading distance of 10 to 30 feet. For supply chain applications, this will affect the use of tags.

Sontec's CEO Dong-Jin Lee pointed out: "The Sontec tag with TI Gen 2 technology is based on UHF Gen 2's first practical RSC management solution for metal applications. Usually, the metal application environment will cause Difficult technical issues.With our new products, retailers can easily dispatch appliances and electronic devices throughout the supply chain without the need for additional handheld or labor-intensive solutions to transport high-metal content materials. The process also enables regular tracking of the retail supply chain."

Mikael Ahlund, Director of asset tracking at TI's RFID Systems Division, pointed out: "When a UHF transponder is near metal, the read range will be greatly affected because the UHF signal will be greatly attenuated on the metal surface. With Sontec, the metal is mounted (Mount -on-metal packaging technology, even if it is attached to the metal surface, UHF Gen 2 tag can also work efficiently, and maintain an excellent reading distance, which helps us to provide a variety of supply chain solutions, so that we On the basis of the standards, an important step has been taken to achieve further performance improvement."

The Sontec tag uses TI’s latest Gen 2 UHF IC chip certified by EPCglobal(TM). TI's Gen 2 silicon chips, which are available in wafer and strip chips, were developed from the most advanced 130-nm analog process node. The built-in Schottky diodes increase the conversion efficiency of RF signal energy, and thus the chip achieves low power. Consumes higher sensitivity from the chip to the reader.
