5. Fingerprint Template Description (ISO standard/ private standard)
The default is the private standard format. However, our devices support multiple data formats. such as ISO/ANSI standard. The device provides both hardware and software. Use the SetTool tool to set the standard, as the following:
 
or you can use our SDK to convert fingerprint data format.
Whether you use SetTool or SDK conversions, you need to be aware of the direction of the fingerprint image. Only the right direction can be compatible
 
6.Description for Related Problem
Currently, we offer comparison library on Android and Windows. Android only supports 32-bit, ARM chip (ARMV7). 32-bit and 64-bit systems are supported on Windows. Other systems or chips can be used in-device comparison.
Special tip: We do not guarantee that all Android devices can operation Comparison Library successfully.
