Enhanced support for Reva Systems' tag acquisition processor (TAP) is also provided. TAP was designed to act as a central command post for numerous networks of RFID interrogators (readers). The TAP is a rack-mountable device that plugs into networks of interrogators and the user's local area network (LAN). It filters and aggregates tag reads before sending the tag data to software applications running at the enterprise level.

High-capacity memory RFID tags revealed

Three new RFID tags based on the RFID Gen 2 chip from NXP Semiconductors are available from RSI ID Technologies (www.rsiidtech.com). Each tag offers additional user memory that allows companies to add a wide range of additional information to RFID tags above and beyond EPC numbers. To create the new RFID tags, RSI ID Technologies used its rapid antenna design process. The process enabled the antenna design and production to begin within just four weeks. By leveraging this proprietary development process, RSI has been able to significantly improve on the industry's typical antenna design turnaround, which can take months.

The OAT tag@source from OATsystems (www.oatsystems.com) is a complete, automated, in-line tagging solution that enables manufacturers to efficiently apply RFID tags to products within production and packaging facilities. This new solution, based on more than 700 months worth of automated RFID-tagging experience across numerous industries, is built on the SOA-based OAT foundation suite that provides proven integration into existing systems such as WMS, MES and PLCs, and is validated on IBM's Premises server. The OAT tag@source comprises all the necessary process steps including encoding, applying, verifying, pallet building, shipping and any necessary rework, and is available in a variety of open configuration options.

Reusable tag lowers cost of ownership

The RFID small rigid tag from Intermec (www.intermec.com/rfid) is a compact, reusable RFID tag that is ideal for harsh industrial applications where ruggedness, chemical resistance or extreme temperatures are a factor. Because it can be used thousands of times, it is even more economical to use than disposable tags. As a companion to Intermec's EPCglobal interoperability-certified RFID large rigid tag, the RFID small rigid tag is available in EPCglobal Gen 2 and ISO 18000-6B protocols. Measuring 1.22 in. × 3.11 in., it is equipped with a wideband antenna design that allows the tag to be used practically anywhere in the world on virtually any surface, including metal, plastic and wood. Its rugged design can withstand extreme temperatures from -40 °F to 250 °F (-40 °C to 121 °C) and long-term exposure to chemicals such as machining oil, methyl ethyl ketone, isopropyl alcohol, acetone and kerosene.
