Toshiba has announced an SD card like you have never seen before. It allows users to store up to 1GB of content, but the content can not be erased or modified in any way. Write once and that’s it. It also can not be formatted. It looks like any other SD card and can be used just like a normal card.
What you store on it stays on it. Toshiba is targeting “governmental offices” and businesses with the Write-Once Card and they have already started selling them in Japan. The company is probably testing the waters with this low capacity card, hoping to deliver media on them eventually.
