SanDisk Corporation has introduced the SanDisk(r) SD(tm) WORM card, a Write Once Read Many (WORM) digital memory card intended for uses such as police investigations, court testimony, electronic voting and other applications where data files must be protected from alteration or deletion.
Digital data written to SanDisk SD WORM cards is effectively locked as soon as it is recorded; there is no physical way to alter or delete individual recorded files. Viewing the data is simple, because the cards are readable in any standard SD slot attached to a computer or other SD-compatible device.
