This would really help in situations where you meet someone who claims to be working for company X and yet you have no way of verifying this outside of trying to get an NPC to respond. To me this is creates a gap in the RP.
Naturally these things could be stolen, and would have to be replaced. But they don't give any real security clearance, which is naturally based on the far more reliable SIC chip.
But a SIC chip doesn't help in player-to-player RP situations.
P.S. On a side note, which I'll just mention briefly, e-note's should get some kind of generic 'Report' format to print out! Everythings ends up as a 'flyer'. This would also help corpie RP...
Thanks.
