Problems solved by technology

However, there is a certain failure rate in fingerprint unlocking, and fingerprint unlocking is subject to the user's fingerprint. When the user is injured or the finger sheds the skin, there will be problems in fingerprint unlocking, and fingerprint unlocking requires a fingerprint recognition device, and the production cost and battery life of the device will increase. affected
The password unlocking and pattern unlocking are too simple, if they are peeped by others, they are easy to be copied, which is not conducive to the information security of the device
