In the meantime, the still hosts pages and press releases that refer to iSDIO as a standard. A page in the site's "SD Standard Overview" section , and the is also available on the SDA's site.

"The SDA made an announcement itself that made it seem like the standard was ratified," Koren says. "There's still a misconception ... people believe the standard exists. That sort of misinformation is still out there."

The confusion over the proposed specification's status may have caused a few companies to bill their own wireless-card products as iSDIO-compliant. When and were announced last year, both products' makers described them as conforming to SD Association standards for wireless cards. The official product pages for and do not mention the iSDIO spec, although Toshiba's FlashAir page does refer to embedded wireless LAN technology that "meet[s] the SD Memory Card standard."

If it doesn't infringe on Eye-Fi's patents, the proposed iSDIO standard would offer benefits to consumers. Unlike Eye-Fi's technology, Toshiba's FlashAir card supports two-way transfers of files between a camera and another compatible device, and Toshiba says its card may be more versatile in terms of development and device compatibility.

"FlashAir is the first card that addresses the new standard set forth by the SDA," says Brian Kumagai, Toshiba America Electronic Components' senior business development manager for NAND flash-memory products. "All SD Card-enabled cameras will work with Toshiba's FlashAir ... in the future, camera [manufacturers] will be able to incorporate additional [wireless] features."
