Problems solved by technology

[0014] At present, fingerprint-based security chip authentication is limited by chip development technology and biometric technology. It can pre-store fingerprint identification codes inside the chip and compare fingerprints inside the chip. Other fingerprint operations, such as fingerprint collection and fingerprint processing There is an external auxiliary chipset or an upper-layer operating system and application, which achieves a higher level of security authentication, but there are still certain security risks
