CopQuest's secured PIN-enabled 16GB flash drive is designed to offer great access control for sensitive files. Enter your PIN and the files are unlocked for read/write access while the device is plugged in to a PC. When the drive is removed the files are automatically locked. The drive incorporates a processor and rechargeable battery and works independently from the PC. If the drive is lost or stolen, it will erase all files if an incorrect PIN is entered 10 or more times. The PIN is user programmable from 4 to 16 digits.
