set
Sets the data groups to read from the chip.
Reading fewer files is worthwhile because DG2 holds the face image and takes most of the reading time. See DataGroupSet for the available selections and for what a selection does not influence.
Return
This instance of the builder for easier chaining.
Parameters
files
The data groups to read, for example MINIMAL_KYC for the MRZ and the face image. null restores the default STANDARD.
