South Korea's LG Innotek, an affiliate of the country's major tech manufacturer, has revealed a new fingerprint sensor that can slot into a space cut into the underside of smartphone cover glass.For the sensor, LG Innotek cut a shallow furrow of 0.01inches (0.3mm) thick on the lower backside of cover glass and installed a fingerprint sensor inside of it.The new module has a false acceptance rate (FAR) of 0.002%, the firm confirmed in a press release.LG Innotek developed a proprietary adhesive to be used to attach the sensor to the glass, securing the commercialization scale of the durability including high impact absorption.The adherent side of the sensor and glass is only 0.0098inches (0.25mm) thick, but it endures impact of 4.6 oz (130grams) of a steel ball dropped from 7.9inch (20cm).LG Innotek expects that demand for fingerprint recognition technology will dramatically increase due to the expansion of the mobile payment market. It notes that market research firm, IHS, reports approximately 499 million fingerprint sensors have been sold globally in 2015 and expects that number will increase to 1600 million units in 2020.Changhwan Kim, Head of the company's R&D Center said, “We are concentrating on all our resources to the development of the differentiated technology based on the creation of customer values.” “We will continue to provide convenient, safe, and pleasant user experiences by launching innovative product.”
