This feature is not possible with BioStar SW and is only possible with SDK. Only FaceStation2 supports the feature but A2, L2, BS2 don't support the feature currently. It might be added to the BioStar SW or SDK in the future for all devices having LCD, but there is no plan yet. If your customer wants to use the feature with A2 or L2 or BS2, please proceed with customization. 


You can send personal message to FaceStation2 for each user if you pre-define the message. The message will be shown when the user authenticate successfully. 

You can define the message at BS2_USER-PHRASE in BS2UserBlobEx structure.
