NEC has won a $4.7 million contract to supply NSW Police with up to 1000 smartphone-compatible portable fingerprint scanners.The scanners will allow officers to register and verify identities on the go, removing the need to return to their stations. The scanners will also alert them to outstanding warrants and other information on suspects.They will enable almost instantaneous searching and enrolment of biometric data on national databases by officers in the field, a spokesperson said. Such databases include the national automated fingerprint identification system (NAFIS) and – when complete – Australia's biometrics identification services platform.The roll out comes more than two years after NSW Police approached vendors seeking such a system.
