One Card System Increases Bank Security Level Function
One card system to increase bank security level features - fingerprint login. Fingerprint identification technology is currently a convenient, reliable, non-invasive biometric technology solution and has great potential for large-scale application. Fingerprints are rare features of the human body, and their complexity is sufficient to provide enough features for identification; scanning fingerprints is fast and easy to use; when reading a fingerprint, the user must contact the finger and the fingerprint collector head with each other. The fingerprint acquisition head is direct; contact is a reliable way to read human biometrics.
