Biometric data found in the fingerprint develops with the individual. Prints are naturally unique and provide reliable recognition points for identification. Once an individual develops a fingerprint that can provide enough biometric data (usually around 12 years of age), they should be able to enrol on a biometric system.
One of the core reasons fingerprints are a popular form of biometric security is that once fully formed, a fingerprint tends not to change until later in life. Most changes that do occur tend to be abrasions to the skin, distorting skin conditions, or loss of a digit. As a person ages, the skin on the fingerprint naturally starts to lose collagen, which results in a degradation of fingerprint definition. This can decrease the number of data points required for identification in an ievo template. While some ievo products offer a solution that can combat some of these instances, our sensors rely on data to be able to be fully effective.
Occasionally, there are some individuals who naturally have ‘problem fingerprints’ (meaning not enough data points are present for positive identification). In these cases, download our Problem Fingerprints guide for help and advice.
