SanDisk Corporation has announced that it is shipping, in volume, 1GB SD WORM cards to Japan's police force.
A WORM card (write once, read many) differs from a normal memory card in that it secures data at the moment of capture and the data cannot be altered or erased. The data can be copied to a computer, but the original information will be archived on the card for as long as 100 years. Further, each card has a unique serial number. This makes it ideal for use in law enforcement, as the digital evidence collected for a case, photos or other data, is preserved with a clear and unimpeachable chain-of-custody.
Japan's police force is one of the first major agencies to adopt WORM cards as a means to secure digital evidence. Other law enforcement organizations are considering it as well.
Any SD-compatible device can read SD WORM cards, but only data collection devices, such as digital cameras, audio recorders or video recorders, that have SD WORM-compatible interfaces can write to the card. SanDisk is working with manufacturers of imaging, audio and video recording devices to implement SD WORM compatibility.
The SanDisk SD WORM card is available worldwide in a 1GB capacity, with pricing dependent upon the quantity ordered. For additional information see SanDisk's website.
