Question about Lupusec RFID Tag - 57199

Hmm, even if it were possible, it would still be interesting to know how SBB sees it :-/ (have you clarified this? Would be interesting to know at this point)?

I think they don't see your picture in the DB or on their mobile phone (control device), then you could feed in any subscription.

This would probably be possible. But the SBB will probably not play along. You could lend your Swisspass to your brother (or someone else) during this time and then they would have sold one less GA.
