Hitachi 's new e-credit system uses an increasingly common biometric technique to verify an individual's identity by scanning the veins in their finger. The finger vein authentication technology isn't new and is in use in cash machines in many Japanese banks , but the key is in linking it to a central database accessible by retailers.
In spite of speculation that any such finger-based system will lead to criminals lopping off people's fingers, Hitachi assures users that any digits devoid of pumping blood simply won't fool the scanners.
