biometric fingerprint scanners, microorganisms, microbial colonies, morphological characteristics, Biometric identification


This study was done by swabbing the devices’ surfaces and inoculating the samples onto Nutrient Agar plates then incubated at 37°C for 24 hours. Microbial colonies on each plate were then classified based on their morphological characteristics. Results show that all biometric surfaces sampled had thriving microbial colonies, in which six classes of morphological variants were identified. Regular decontamination of the biometric fingerprint scanners and other hygiene practices should be strictly adapted. Key.
