Fingerprint security is definitely a better alternative to passwords.
When using passwords it’s not easy to memorize them, as the strongest ones are using small and capitalized letters, numbers and symbols, plus that even so they are not impossible to break.
Your fingerprint never changes, this offering you the possibility to have your “password” with you wherever you go, without worrying about losing it, or that someone might see it.
If you are looking for an affordable device that provides fingerprint-based access to your computer data, there is the USB Fingerprint Security Lock Flash Disk (16GB) from Chinavasion. It is available for EUR 39.47 and provides 16GB of portable storage, as well as file encryption and the option of setting password-based access instead of fingerprint-based access.
It is compatible with Windows operating systems up to Vista and features USB 2.0 connectivity, 16GB flash memory, the Atrua Wings ATW310 scratch-resistant fingerprint sensor, 8MBs reading speed, 7MBs writing speed, and a size of 11 x 26 x 76 mm.
The drive comes in white with silver.
