U20-ASF-BT2 Fingerprint Recognition System
The U20-ASF-BT2 is a sophisticated, standalone fingerprint recognition system that captures, stores, and verifies fingerprint data for registered users. As the wireless variant of SecuGen’s Unity OEM Modules, it is a self-contained, all-in-one fingerprint system designed to operate independently without the need for an external PC.
U20-ASF-BT2 Fingerprint Recognition System Description
The U20-ASF-BT2 is an advanced, stand-alone fingerprint recognition system developed by SecuGen, designed to provide reliable, secure biometric verification without the need for an external PC. Ideal for applications in access control, ATMs, handheld devices, point-of-sale systems, industrial equipment, and more, the U20-ASF-BT2 offers a compact and rugged design that ensures durability in a wide range of environments.
At the heart of this system is the SecuGen U20-A, an FBI-certified FAP 20 fingerprint sensor, known for its high accuracy and performance. The device is integrated with a programmable Single-Board Computer (SBC) that includes a powerful CPU, SDRAM, flash memory, and a Bluetooth module, allowing seamless wireless communication with external devices.
The U20-ASF-BT2 can easily communicate via Bluetooth, making it highly versatile for various installations and allowing integration with SecuGen’s USB fingerprint readers for even broader implementation. This makes it ideal for industries where biometric authentication is critical, offering a streamlined solution that doesn’t require a connection to an external computer.
Whether used in access control units, door locks, handheld devices, or other embedded solutions, the U20-ASF-BT2 delivers fast, accurate fingerprint identification and verification, ensuring secure and efficient user authentication in any environment. With its small form factor, long-lasting durability, and Bluetooth compatibility, it provides a complete, self-contained biometric solution that meets the needs of modern security applications.
