On April 18, 2017, the leading semiconductor components distributors dedicated to the Asia-Pacific market - Dachang Capital Holdings announced that their friendlife launched Betterlife BF3290 fingerprint identification chip solution, can be applied to smartphones , Tablet and computer peripheral equipment, GPS navigator, etc.
The smartphone's fingerprint recognition is hot, and the reason is that the extensive popularity of smartphones and related applications based on smartphone certification are explosive growth. On the other hand, as the global mobile payment market has spawned, the fingerprint recognition chip solution has set a boom in the fingerprint payment field. Undoubtedly, fingerprint recognition has become a standard for smartphones.
The Betterlife BF3290 / BF3291 fingerprint recognition chip scheme for Dabin Dad is a press-based fingerprint recognition sensor based on RF detection technology. Its detection sensitivity is high, and high quality fingerprint images are obtained by detecting a pattern of finger layers. BF3290 / BF3291 adopts surface planarized injection packaging technology, which can be cut at 9.0-11.5 mm sizes, with superior antistatic, abrasion resistance, corrosion resistance and other characteristics. The built-in oscillator circuit of the chip, power-on reset circuitry, supports surface coating process, support 360 ° any direction touch identification, in line with mobile terminal requirements, and enhance user experience.
