OPTOELECTRONIC FINGERPRINT SENSOR FOR MOBILE PHONES

摘要

An optoelectronic fingerprint ID solution has been developed for mobile phones. This rugged, ultra-miniaturized optical sensor can be configured to be installed in the corner of the cell phone case. Biometric fingerprint sensing will reduce cell phone theft, and allow user identity verification for financial transactions and database access. Multifunctionality is supported to allow cursor control, scanning of bar codes or scanning of URL addresses (for OCR reading). The proprietary sensor chip interfaces directly to the DSP microprocessor bus in the mobile phone.
