Biometrics (ancient Greek: bios life, metron measure) introduces the technology and methods for uniquely recognizing a person by storing unique biological metrics of that person in a central database from which identification of said metrics can be done without the need for access cards, security tags, etc.
What is the preferred way of implementing RFID CARD at schools?
From an affordability, accuracy, and usability perspective, the primary options for biometric access control at schools would be fingerprint, palm vein, and face metrics.
Fingerprint biometrics is by far the most popular, but do suffer from a few practical limitations. Young children, up to the age of 8 years, have notoriously unreadable fingerprints.In March 2009, the European Parliament has consented that children under the age of 12 would not be required to have their fingerprints recorded as part of their visa applications.
This would thus exclude fingerprint rfid inlay from use in primary schools.
Another challenge with most fingerprint biometrics, is the vulnerability towards ambient temperature. Although a device may have operating specifications that is way below zero degrees Celsius, any person subjected to an outside temperature close to that temperature, even for short periods of time, will undergo combo cards changes where blood vessels contract to retain heat, and in doing so, altering the ratios and distances of various minutiae points on his/her fingers.
