Increasing adoption has helped bring down the cost of biometric devices. Factors like an economy of scale, increasing production and electronic components getting cheaper, have helped biometric systems to become affordable for small business and even for individual applications. Slashing prices are particularly evident in the case of fingerprint scanners. Earlier, only high end or flagship mobile phones were equipped with fingerprint sensors, but now even a $100 smartphone offers a capacitive fingerprint sensor. Fingerprint recognition systems, which were earlier used only in high-security facilities or restricted areas, are now commonly seen everywhere. Let it be office doors, server rooms, schools, banks, POS, etc., fingerprint scanners have made their way to everyday life. Due to mass production, building blocks of biometric systems are getting cheaper and new entrants are offering very competitive prices. Technological enhancements and the introduction of new hardware also slash prices of previous iterations.
There are various elements to consider before choosing any modality to employ for a biometric application. Level of security required, cost of the biometric system, return on investment, etc., are some of the elements that may become deciding factor in employing a biometric recognition method.
