Biometric Technology empowers recognizable proof of individual dependent on inborn physical qualities. There are a few body parts which are normally utilized for biometric distinguishing proof, for example, fingerprint, face, iris, and palm. Fingerprint is the one that most broadly utilized for distinguishing proof framework. Other than demonstrating interesting example for every individual, fingerprint likewise have different characteristics that make it famous biometric item, for example, simple to catch, reliable all through human life expectancy and empower fast check. Today, fingerprint machine has been generally utilized as standard office types of gear. Its utilization includes assortment of purposes. It is utilized for controlling the physical security get to, validating benefit for specific business process, and furthermore recording time attendance. This article basically talks about the last issue, which is to assist you with choosing fingerprint machine as a time attendance recorder. Here are a few highlights that you should consider when picking fingerprint machine.
- Type of Sensor: Sensor is the most significant piece of may cham cong van tay. It catches the picture of fingerprint before being changed over into one of a kind recognizable proof number. There are two most regular sorts of sensors: optical sensor and silicon sensor.
- Optical Sensor is the most seasoned sort of sensor. It is simpler to execute and moderately progressively stable in different room temperature. Anyway its presentation will be exceptionally reliant on the clearness of the optical surface. Consequently, when picking fingerprint machine with optical sensor, you ought to think about the covered optical sensor. The coat keeps the sensor from being contacted straightforwardly and keeps up the clearness of optical surface.
- Silicon Sensor is more up to date innovation, it builds fingerprint picture by mapping weight or capacitance contrasts between the skin and the silicon chip. This innovation offers a few preferences like creating an increasingly exact fingerprint picture, consuming littler space, and requiring littler to spending actualize. Be that as it may, unprotected silicon sensor won’t be strong for visit use. Therefore, Silicon Sensor isn’t usually utilized for open use, for example, time attendance machine that will be gotten to many times regular.
Limit of fingerprint format is most extreme number of fingerprint picture that can be put away inside the Fingerprint Machine. It is prudent to pick a fingerprint machine that has fingerprint format at any rate double the greatest measure of worker. By having number of fingerprint format double the measure of representative, every worker can enrol a reinforcement finger if the machine has an issue for ID. Limit of log support is the most extreme number of log exchanges that can be put away incidentally inside the Fingerprint Machine. Time attendance exchange log is typically put away for a few days before being downloaded into database cut off. Along these lines, the limit of log support must be a few times normally in excess of five times greater than measure of representative.
