A In general, there are two types, the sensor itself has a sleep wake-up function and is realized by an external touch chip. Different fingerprint module implementations will be different.
-
A According to the customer's specific situation, it can generally be set to 3 or 2. The higher the security level, the more matching feature points, and the higher the recognition rate.
-
A Generally, after purchasing the fingerprint module, refer to the communication protocol of the module user manual to write commands to achieve the required functions. Please be sure to carefully check the user manual. If there are technical problems during use, we will provide technical support.

A In principle the power consumption of the optical module is higher, the power consumption of the semiconductor module is lower. Our fingerprint modules have a touch wake function and the power consumption in standby is only at the microampere (ΜA) level and only at the milliampere (MA) level when making registration comparisons. As long as the touch wake function is used effectively, the power consumption problem will be greatly reduced.
-
A When purchasing our modules, you can go to the download centre on the official website or get the supporting test software, specification book and other information from the sales manager. Modules using the serial port for testing need to connect the serial port to the computer via a TTL to USB adapter board. Modules using the USB port for testing are directly connected to the computer and can test their basic functions by opening the test software.
