datastorage package contains applet for personas data storage.
This Link used for VirtualCard implementation for data storage functionality - let’s call it Virtual Data Storage Card (VDSC) (see VirtualCard interface)
DataStorage Applet instance stores VirtualCards for all personas, registered in Auth Applet instance.
Each persona has their own Private VirtualCard, accessible ONLY after this persona authenticated in Auth Applet instance.
All personas registered in Auth Applet instance has Common VirtualCard (for such common services like Household).
After a persona authenticated in Auth applet instance - common VDSC must be activated.
Off-card entity (POS) is able to switch between Common and Private personas VDSC during authenticated session via SWITCH VIRTUAL CARD APDU command.
