The Law Department of the City of New York uses “hand geometry” scanners known as CityTime. The website of CityLimits.org #629, March 3, 2007, explains that the Ingersoll-Rand Hand Punch 4000 units clock workers in by reading the specific geometry of their hand.
At least a dozen city agencies, comprising some 13,000 workers, are now using biometric time clocks, and another five agencies will do so by summer 2008. The program will eventually include 80 agencies and 160,000 city employees. For non-exempt employees of the law department, this new technology holds out promise of greater accuracy and reliability (See my post of June 6, 2006: Cargill’s law department and fingerprint identification.).
