WJ Provides Open Source Software for MPR Series RFID Cards

1 January 1970

WJ Communications, Inc (NASDAQ:WJCI), a leading designer and supplier of RF semiconductors and RF modules, today announced that it is offering the dynamic link library (DLL) for its innovative MPR Series RFID Card products to the public on an open source basis. The DLL will be provided along with projects (code call examples) and documentation sufficient to enable customers to rapidly develop custom reader control software.

"Providing our software DLL on an open source basis is another customer focused move by WJ to promote and facilitate the use of the MPR Series RFID cards in handheld, printer, portal or other reader applications," said Dr. Michael Farese, Ph.D., chief executive officer and president of WJ Communications. "We have been providing a host control program with each reader sold, and providing the open source DLL will make it faster and easier for our customers to build on our code to create value-added host applications. Offering the open source DLL exemplifies the strong steps WJ is taking to support our MPR Series RFID Card products, simplify product evaluation and use, and reduce customer application development time, enabling OEM reader end-products based on reader solutions provided by WJ."

WJ's MPR Series PC Card(TM) Products, the MPR5000 and MPR6000, operate in the UHF frequency band and are based on the PCMCIA Type II standard. Each MPR can read EPC Class 0, 0+ and EPC Class 1 tags and program/write 0+ and EPC Class 1 tags. The MPR 5000 includes a single integral antenna while the MPR6000 includes two separate antenna ports. Operational control is performed via high-speed parallel communications over the PCMCIA bus or via serial communications through the standard 68-pin PCMCIA connector.

The MPR Series units operate on only 5 volts, and the PC Card(TM) format greatly simplifies RFID reader installation, setup and operation. The compact PCMCIA type II form factor is realized using highly integrated WJ semiconductors, and the RF architecture forms the basis of WJ's recently announced UHF Integrated RFID Transceiver ASIC -- The WTX1000.
