How To Choose a Fingerprint Reader

The fingerprint is used to identify and verify the identity of an individual. The fingerprint reader is now a widely used piece of equipment in varied business establishments to monitor the punctuality of their employees as well as to make use of the fingerprint instead of a security password. Gone are the days that the fingerprint reader was an exclusive device for the use of the police and military sector to track down criminals. In choosing a fingerprint reader that would suit your needs, the following factors may be considered:

  1. Your first step is to be familiar with the different fingerprint reader designs. There is a wide array of fingerprint readers available on the market, manufactured by different companies. Features would differ according to the manufacturer, but each would function in the same manner. The four types of fingerprint reader according to sensor design are optical, ultrasonic, passive capacitance and active capacitance. Another fingerprint reader that is widely used for outdoors purposes is the weatherproof fingerprint reader.
  2. Choose a fingerprint reader with the capability to capture the fingerprint image. The fingerprint reader using an optical sensor is not susceptible to electrostatic discharge damage like the capacitive sensor. The downside of this sensor, however, is that the imaging capability is affected by the quality of the skin on the finger. With a scratched or dirty finger, it will be difficult to image its print properly. The ultrasonic sensor has the capability to capture the image even if the skin of the finger and the sensing surface are not clean. The passive capacitance fingerprint scanner, on the other hand, is like the optical sensor. It requires that the skin of the finger be clean.
  3. Optical sensor fingerprint scanners work like a digital camera, while passive capacitance works through the electrical value registered in the fingerprint pattern of the finger. The active capacitance system is like the ultrasonic fingerprint reader. It measures the ridge patterns of the dermal layer of the skin. It does not require that the skin be clean nor its sensing surface. The active capacitance fingerprint reader could capture the image even if the epidermal skin is damaged.
  4. Consider the reliability of the fingerprint reader through its identity solution provider. Readers to be chosen must be those that are used by millions of people around the world. Its software solutions should support the industry’s variety of security devices. It should function to its purpose, help the business to reduce costs, eliminate security risk, and maintain compliance.
  5. Evaluate the manufacturer’s technical support. Another important factor to consider in buying a fingerprint reader is the manufacturer’s technical support. It is a given fact that 100% reliability of any product is not reachable. In cases that problems arise in the use of the product, the consumer relies on the technical support that the manufacturer could offer.

For the fingerprint reader used to log on to different websites, compatibility with the various web browsers is an important consideration. If you were a user of different web browsers, installing a fingerprint reader on your computer that is compatible with only one web browser would be disadvantageous.
