The main reader hardware management methods in the XReader class are:
Function Description
Open Open a device and return the device capabilities. This method establishes an
exclusive link to the device; no other processes will be able to use the device
until you close it. The application must open the device before use.
GetStatus Get the status for a device. You would normally check the device status before
captures to ensure that the device is functioning and there are no error
conditions.
Returns an object of type
ReaderStatus which describes the current status
of the reader.
Calibrate Calibrate a device. Some devices are self-calibrating. Ambient light or
temperature can affect calibration, for some devices. Calibration can take
several seconds.
Reset Do a hardware reset on the reader. Hardware resets are typically needed only
after a hardware problem (e.g., the device is unplugged or receives an
electrostatic shock). Hardware resets typically only take a few milliseconds.
Dispose Close device, release memory, remove child objects.
