Working principle1, a fingerprint algorithm fingerprint feature extracted from a fingerprint image acquired feature, information representative of the fingerprint.Fingerprint storage, comparison and search features are accomplished by the operation of the fingerprint.2, two fingerprint processing procedure comprising: a fingerprint and the fingerprint matching process login process [wherein the ratio of the fingerprint into the fingerprint matching (1: 1) and the search fingerprint (1: N) in two ways].When the fingerprint logon, a fingerprint for each entry twice, and twice entered image processing, synthetic templates stored in the module.When fingerprint matching, fingerprint sensor, to verify fingerprint image input and processing, comparison and matching with the fingerprint template module (if matched with a template specified in the module, called the fingerprint matching method, i.e., 1: 1mode; if matched with a plurality of templates, called fingerprint search methods, i.e., 1: N mode), the module gives the matching result (pass or fail).technical parameterDimensions (23.3 * 20.3 * 48.1)Supply voltage: DC 3.3VSupply current: Operating Current: <;;60mAPeak current: <;;60mAFingerprint image input time: <;;1.0 secondsWindow area: 15.3╳ 18.2 mmResolution: 500dpiAny issue at all, just let us know and we'll fully refund your order.
