How do we test our fingerprint modules?
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.
What interface do fingerprint modules use to communicate?
Our fingerprint modules ID1028/ID1020/ID1011 support both UART and USB interfaces, the rest of the models only support UART interface for communication, UART is TTL logic level. Please pay attention to this when selecting a module.
What happens to the finger will affect the recognition effect?
Generally, when the fingers are severely damaged, extremely dry, and extremely wet. There are also oil stains, water stains, a lot of sweat or a lot of dust on the finger or fingerprint collection area, which will cause the fingerprint to fail. It is recommended to take corresponding measures when using the fingerprint device in this situation.
Which one is more durable, optical or capacitive fingerprint module?
In terms of durability, the contact surface of the capacitive fingerprint is relatively fragile, and it is easy to cause aging and damage due to time issues. The optical fingerprint recognition has passed the test of time, and even the glass plate on the recognition head does not need to be covered with coating. Optical fingerprints are also much more adaptable to the environment, and are more suitable for use in the humid south.
