In each step, take close-up photography of each element of the surface after removing the cast. At NEC, were proud to be the provenmarket leader infingerprint recognitiontechnology; ranking first for accuracy and speed in two successive National Institute of Standards and Technology (NIST) benchmarking tests. [9] Since this study was controlled, it is known that the use of this further application with the MALDI/TOF MS would be effective. The pattern can then be visualized and rest on the surface for months without alterations. This makes it extremely difficult for anyone to forge someone elses identity.
