VFS301 FINGERPRINT SENSOR PRODUCT BRIEF Durable Swipe Sensor Featuring LiveFlex® Technology
PRODUCT DESCRIPTION VFS301 is a durable high performance pe rformance dual-line-imaging (DLI) fingerprint sensor with a small exposed form factor and low power consumption. The cost effective VFS301 is designed for optimal integration into notebook computers, tablet PCs, and PC peripherals, and can be colorized to to satisfy OEMs’ increasing requirements for customization and end consumers’ desire for improved aesthetics on notebook PCs. The product consists of custom custom silicon chip bonded to a Kapton® plastics flex circuit, known as Chip-On-Flex (COF). The sensor captures the unique features of a 3-D fingerprint image using a patented technique to detect and measure the ridges and valleys of a live finger. finger. The product uses an industry
VFS301 Chip-On-Flex Fingerprint Sensor
leading, patented image reconstruction algorithm from Cogent Systems to acquire a high quality fingerprint image. Users swipe their finger over a durable Kapton® plastic surface for authentication, identification, securing data, and more.

VFS301 Fingerprint Sensor Module: VFS301 COF fingerprint sensor attached to printed circuit board. Typical T ypical dimensions: 22.8mm (l) x 9.97mm (w) x 4.5mm (h) (with mount tabs)
TECHNOLOGY Validity’s patented LiveFlex® Technology is the foundation for developing fingerprint sensors with the highest levels of performance, durability, cost-effectiveness, and flexibility. SOLVES DURABILITY ISSUES
• Real COF Technology: Fingerprint sensing area and silicon die are sepera ted • Finger touches plastic, never silicon • RF sensing penetrates deep into living tissue of a finger through robust Kapton® film. • Plastic surface provides industry leading resistance to impact, abrasion, liquids, chemicals
VFS301 integrated into USB Fingerprint Reader Peripheral
• High resistantance to Electrostatic Discharge (ESD) SUPERIOR IMAGE QUALITY
• Superior raw image quality allows sensor to work with any 3rd Party Matche r • High Frequency (16MHz) RF retrieves stronger signal from finger • Differential pickup performs “noise cancellation” • Multiplexing transmitters allows focus on ‘World Class’ RF Receiver with full 8 bit images • 9 bit A to D internally allows more dynamic range • LiveFlex provides the best Images, which provide best FAR/FRR performance statistics ALLOWS CUSTOMIZATIONS
• Bi-color back-lit LED Ilumination options • Color Options (any Pantone® color) • Small footprint with flush mount capability and multiple z-height options
