In the existing BioStar 2, even if the 3rd party controller used the Smart Card in LSB format, the Suprema device could only transmit data in MSB format. From BioStar 2.8.16, Suprema supports the option to send the Smart Card in the LSB format from the Suprema device for the convenience of customers.

* This function is available only when you match the version of BioStar 2 and the firmware version of each device.
