Radio Frequency Locking USB Flash Drive

This flash drive also includes a RF transmitter. What is this transmitter for? I'm glad you asked! Once the transmitter is 2 meters out of range the drive will lock, rendering the data on the USB drive inaccessible. If you forget or manage to damage the transmitter, a password can unlock the flash drive. There is also a timer that can lock the flash drive anywhere from 1 minute to 8 hours.

No word on the size of the flash drive, but this "peace of mind" is available for a mere $29.
