Sometimes, when we refer to a group of devices, Suprema agents may say a 1st generation device, entry-level device, 2nd generation device, or On-Device AI device. 

If you are not familiar with them, they mean the following. 

1st generation device:

BioLite Solo, BioLiteNet, BioEntry W, BioEntry Plus, BioStation, BioStation T2, FaceStation, D-Station, Xpass, Xpass S2

1st generation entry-level (blackfin) device:

BioLite Solo, BioLiteNet, BioEntry W, BioEntry Plus, Xpass, Xpass S2

* These devices do not have an OS.

2nd generation device: 

BioEntry W2, BioStation L2, BioStation A2, BioStation 2, FaceStation 2, BioEntry P2, BioEntry R2, CoreStation, BioLite N2, FaceLite, XPass 2, XPass D2, X-Station 2

On-Device AI device:

FaceStation F2, BioStation 3, BioStation 2a

2nd generation devices are also sometimes referred to as BioStar 2 devices. They were designed for BioStar 2 and introduced after BioStar 2 was released. 

They can only use limited features in BioStar 1 v1.92 or above because these devices were not initially designed for BioStar 1.
