CORSAIR Flash Padlock 3 32GB Secure USB 3.0 Flash Drive with Keypad (CMFPLA3B-32GB)

The Corsair Flash Padlock 3 is a 32GB USB flash drive with a numeric keypad built into the body: you enter a PIN on the drive itself, and until you do, a computer does not see the contents at all. It is a straightforward answer to the ordinary problem of carrying files that would cause real trouble in the wrong hands. Security is handled in hardware, with 256-bit AES encryption on the drive meeting the FIPS 197 standard, so there is nothing to install, no drivers and no reliance on the host machine's software. That also means it behaves identically on Windows, macOS and Linux, including on a computer you do not control, such as a print shop counter or a client's desk. The interface is USB 3.0 and backward compatible with USB 2.0, and the ruggedised rubber housing is water-resistant and shockproof, which matters for something that lives in a pocket or a bag. It carries a five-year limited manufacturer warranty. It suits anyone who moves sensitive material between places: contracts and client records travelling between offices, accounts data, medical or academic files, a photographer's shoot going out to a client. If the drive is left behind in a rickshaw or forgotten in a machine at a print shop, the files stay locked behind the keypad rather than open to whoever picks it up next.
