Sony has finally delivered on its Mofiria
promise with what it claims is the world's smallest and lightest finger vein reader. That assertion may be challenged by Hitachi
, whose 3mm-thick scanner
promises to be even smaller, but the critical difference here is that the FVA-U1 is about to go on sale in Japan come December 18, whereas Hitachi's hardware is nowhere to be found. The Sony scanner weighs a measly 33 grams, hooks up via USB, and adds an extra layer of biometric protection for your most precious data. Whether carrying around an extra dongle just to protect some Excel spreadsheets and your Outlook account is worth it, we leave up to you.
